Transcripts

hi pram welcome to the

interview as you know this this

interview will be recorded it might be

posted on social media uh but we can

start so I understand that you are

applying for one of the large

organizations now and here we are trying

to prepare a mock interview for that

yeah why don't you start up with

yourself your background your

career yeah so my name is pritam salun

uh I have completed my bachelor's in

engineering from information technology

background from Pune University so I

recently graduated in 2023 so uh after

graduating I started working with uh one

of large mnc's uh so I'm working at TCS

uh I'm working there as a Java developer

in a banking project so we are we are

implementing a banking uh teller

solution for Middle East Bank so yeah uh

yeah that's it about me I'm Ed about and

I'm interested in cloud and devops I'm

passionate about it so I'm learning it

on my

own right uh did you have any cloud and

devops experience while you're working

in your organization at the

moment uh we cannot say completely cloud

and devops like full-fledged experience

as my role is mainly mainly revolves

around uh Java Java development but uh I

have done few things uh in uh in Linux

like automating automating the like V

send patches so automating that patching

process like using bash scripts uh yeah

I've done few things and I I've done

projects on on my own related to cloud

and Dev okay

right and now this particular job

description as I understand it's mostly

Linux focused it's networking

Focus yeah how in depth are you

comfortable with these topics

yeah I have uh the basic understanding

of uh Linux operating system and uh

networking all the basics of it and I've

also did some like used Linux for some

projects and used it for a little while

so I have like uh few commands and that

I have experience of that okay all right

so let's start with the easy questions

first and let's see how in depth we can

go into it yeah so first can you explain

me the concept of user and group

permissions in

Linux yeah so user and groups they are

like uh different entities made in Linux

uh to separate the uh different

permissions for a file or like file so

uh users are there are different users

like root users uh system users and uh

to users we can uh Define uh different

uh permissions so there are three kinds

of permission read write and execute so

so in Linux we can give permissions to

user uh then groups then there is one

others so to all these three entities we

can uh give permissions in users a

single a single uh like user will get a

permission group would be a group of

users which will Define in Linux and

will once the permission is given to the

group suppose I give read and write

permission to a specific group so all

the users in that group will uh will

will be having that permission to access

the file yeah so yeah got that all right

so in terms of creating and mounting uh

new file system can you describe the

process on how it is

done yeah creating and mounting new file

system yeah

so

uh we can create new file system in

Linux uh using like first checking our

disk with uh S command and then creating

uh like new new new Partition using f

disk command so it will uh it will uh

create new Partition for us we can

specify uh like what what kind of

partition we need then after creating

the partition we'll need to format that

partition so that we can uh use it and

then once the partition is created we

can mount it uh using like uh Mount

command and then we can create

directories on it like mkdr we can

create directories on it and use it in

our system y that's correct so I was

looking for the two words Fisk and mount

so yeah you you covered them

both what's the difference between the

system package managers like yum and

apt okay so uh in different uh different

Linux uh distributions use different uh

different system package managers uh

like uh in uh in I think in UB 2 it's

yum uh uh and in red Linux there is app

so both package managers uh they are

they used to uh they are used to like uh

do package management for the system so

installing new packages uh so uh we can

install different dependencies uh we can

get uh repositories uh install plugins

uh we can uh install multiple packages

at once like group installation

so uh to use uh package manager like y

we can use sud sudo Y and just install

and the name of the package and it will

install that package

okay can you tell me what these two

commands are used for VM stat and net

stat okay so these both are used for uh

like uh getting the statistics of our uh

Network info and about like system info

of our our our Linux system so vmat is

used for like the virtual memory

statistics so and VM is used for virtu

virtual memory statistics the size of

the memory CPU it is using the paging

blog iio uh so vmat once the command and

there are some Flags so after entering

that it will show information related to

it and network statistics like net stat

is used for Network statistics so it

will display different network

connections routing tables and uh all

the information related to uh

Network

okay so let's let's assume that you

running a Linux based Cloud instance and

there is a service

outage how would you start approaching

that

problem yeah so first I'll check if I am

able to connect to that uh system or not

so I'll first SSH uh into

it uh then after connecting uh so there

is service outage means like we are not

able to connect to that

system yeah yeah so uh I'll try to check

if we first I'll do SSH from my system

if I'm able to access it then I'll check

uh which device are we trying to access

it where issue is getting caused then

I'll check the security groups if it is

allowing like firewall rules uh so for

ec2 I can check the rules for inbound

SSS traffic for the IP assigned to that

ec2 uh then uh uh user account I'll

check if there are any issues with the

user

account so if I'm able to check if I

able to connect to that ec2 and some

other devic is not able to connect then

I'll check about that like specific uh

issues related to the device which we

are trying to connect it

from okay can you tell me that the few

commands that might help you in doing

all these

activities yeah few few commands uh

would be uh first uh we can check

security groups uh that we can check

from the AWS console then uh we can uh

we can use like uh status of SSH like

are we able like SSH Services running or

not that we can check like like status

and sshd so it will show us the like

status and if it is not working we can

start sshd then if there are some s key

issues we can check the permissions

using CH mod command for the key if that

Keys is like the private key pem keys is

accessible or not then for user account

issues we can check using uh like uh we

can check uh user accounts using Pudo

cat Etc password so it will like pass WD

it will show like uh usern names uh for

different uh users so we can

troubleshoot it in this way okay and if

the problem is that a Linux server

cannot access

Internet okay how would you go about

that so if Linux server is not able to

access Internet uh we can uh we can

check uh its uh

uh nackle groups I think so uh we can we

can check

if a Linux server is not able to access

Internet first we can uh check the IP IP

address uh like by running the command

IP addr so it will it will show first

our like our network interface our IP

address then we can check the route if

it uh if it is uh routing we can ping

like we can ping any site like uh if if

we are able to reach that site or

not so yeah we can check configuration

configuration files like DNS

configuration using resolve. config file

we can check in that okay so yeah if you

if you need to identify how many Network

Hops uh is your server making for

connection what command would you

use uh Network Ops I think we can use

trace route uh for that so we can get uh

the like how many Network Hops uh are uh

it is making um

so we can we can install like sudo AP

install we can install trace route and

then we can use like if trace route

google.com so it will display us uh like

the Hop number and uh

like uh details about about that

connection okay now in terms of users uh

can you explain me the concept of user

account with the Pudo access

and how is it different from a root

axis okay so uh root is root user is the

like highest privileges it is the root

user and super user is uh has lower

privileges than the uh root user so uh

Pudo Pudo user is like Pudo stands for

super do so it it is granted permissions

to execute command as the like the root

user but uh Pudo pseudo commands like

author Pudo sudo commands have few

limitations over to the root

user

okay now in terms of networking can you

explain me the difference between UDP

and

TCP yeah so UDP UDP stands for user

datagram protocol and TCP stands for

transmission control protocol so TCP is

for uh reliable uh communication for

reli Reliable transmiss so what TCP does

TCP first does a three-way handshake and

first make first make sure that the

connection is made properly and then

starts transmitting the data uh and UDP

is UDP doesn't make a doesn't starts

with the connection it starts sending

data as fast as possible and in TCP data

will be transmitted into an order and uh

in UDP data won't be transmitted like

there is no guarantee of order or

reliability so there are different use

cases for TCP and UDP so suppose we need

to send reliable like we need to have

sure shity that data will go like

suppose we need to send email so we need

to send the complete email so we like

protocols will be TCP like for https

like we want to load a website protocol

will be TCP but for like online gaming

and video calls uh and there will be

protocol UDP because uh we are not uh we

want uh to run to run it in real time

even if there is some lag that is okay

so that's uh that's when we'll use UD so

that is the major difference

okay so let's say you are a user just an

internet user and you go through you

want to reach a website

abc.com yeah so what happens once you

press abc.com in your browser what

happen in the

background yeah so one I I enter like

let's go with the example of google.com

so that would make it easier so suppose

I enter google.com in my browser so my

browser would first look uh for like it

will try to resolve this DNS so there

there would be there will be coming the

concept of DNS domain name system so uh

it will try to look for the google.com's

IP address so first it will find it in

the like try to search it in the browser

C if I have visited that site earlier

that it will find it in the browser cach

if it is it is not found in browser

cache then it will look up to the like

my internet providers cache or the

system cache so generally it is found in

one of these cache and it will establish

TCP connection with that IP address and

I'll get served the https like the HTML

pages of the content of the site but uh

let's suppose a case when it is not able

to resolve it then there will be a

recursive DNS query so there there are

two types of quer is recursive and

iterative so Suppose there will be a

recursive query so what it will do it

will request to the root root server so

after that google.com one more dot will

be there so that is the root server so

root server will say like I don't have

address for google.com but hey I have

address for that do at the top level

domain so it will return the server of

the top Lev domain.com then uh to it

will again Ask the IP address for

google.com to the top level domain so it

will return the address for the

authoritative server of the like Google

and then the google.com that

authoritative server will return the IP

address so in this way the connection

will get

established okay can you explain me why

the concept of

firewalls concept of firewalls yeah so

firewalls are basically used to have

better control and security over our

Network so firewalls are like uh

essential essential network security

devices so they will uh control the

incoming and outgoing traffic they will

also monitor so there are different

firewalls like uh we can also say in AWS

there are security groups there

are network access control these are

also types of firewalls so they will

they they will inspect the incoming

traffic we can set different firewall

rules to like allow allow only from a

specific spefic IP address or from a

specific range of IP addresses uh or we

can set up like different conditions if

uh we are getting some kind of malicious

traffic then we can block it so this is

what firewalls are used for

okay explain me the purpose of a subnet

mask subnet mask

uh subnet I know subnet subnet mask uh

like like the after IP address we use

that slash and 32 for the cidr range

yeah so subnet mask we used to like uh

creates

uh uh create a specific number of IP

addresses in a subnet create a network

in a subnet so subnet mask is a like

32bit number so uh we for example we can

say there is some IP address and slash

there is 32 then if use like 31 there so

it will be the calculation will be like

32 minus 1 so there will be only one IP

address getting generated out of

it uh so yeah that's about subnet mask

do you know the computation of 32 and 28

24 so on what basis are the number of IP

addresses

calculated uh are based on the uh like

octed

uh the the capacity that that each uh

each can hold so they are calculated

based on that that the highest they can

hold from 0 to 255 so uh yeah so if it's

a sub mask of 16 how many IP

addresses yeah so it the calculation

will be like out of 32 minus 16 then the

uh number would be uh 16 and then 16 the

uh power of 16 power of two like 2 ra to

16 and the the number calculated uh will

be uh the number of IP addresses we'll

be able to get uh like a lot of like

something 65,000 something a lot of IP

addresses can be generated out of that

uh I all right one more networking

question uh can you how do you

troubleshoot a situation where two

devices on the same network they are not

able to communicate to each other

okay two devices are on same network but

they are not able to con uh so uh we can

we can check the both uh uh inbound and

outbound traffic rules Like knle rules

for both of them uh so if the we can

check if what what conditions are set

there like what are they allowing what

inbound traffic and outbound traffic are

they allowing we can set each other's IP

addresses as allowed in the inbound and

the outbound so that they can access

each

other we can ping one from the another

so ping IP address of the another device

from one and check if what's happening

or yeah okay all

right uh now coming back to your

profile you said that you have worked on

Java yeah how comfortable are you

working with python or go or any other

language yeah I'm comfortable uh because

uh like in college days also I have Lear

learned python as part of curriculum and

uh mostly programming languages will the

basics of programming will be similar

only there will be syntax different so

with help of like documentation and few

practice practicing for few days I think

I'll be comfortable in python or even go

okay now have you had any experience in

creating uh security uh in terms of

protecting against common attacks like

SQL injection cross-site

scripting uh yeah so uh for against SQL

injection and cross-site scripting I

haven't worked on but uh in my work

experience I worked on securing

applications against tampering so uh

suppose if application uh uh when a

client like client is sending something

to the like the request response client

is sending to the server and uh in

between uh if the network is

uh like if Network gets uh what we can

say tampered and someone tampers the uh

uh the response uh like the request

being sent to the server and if he

modifies that request Pampers that uh so

it can affect the application so the

approach Ive used uh I've used was to do

server side and client side hashing so

in that request uh first the client will

generate a hash and it will send that

hash to the server and if if the hash

gets matched only then the request will

get accepted otherwise like we can log

out or we can report that issue and

report that incident so in this way we

can handle security for

tempering okay now there are different

types of wireless network security

protocols so have you heard of we WPA

and

WPA2 uh yeah I have heard of uh w w web

like WP

so these are related to wireless this in

daytoday general like using Wi-Fi I have

used them so WP like WP is like old

older one and WPA is also I think now

older one like WPA was vulner vulnerable

to few few attacks so I have myself like

tried to hack into few Wi-Fi using like

like different tools so to get the

password so WPA was uh vulnerable like

there was one button uh on the routers

which was used to reset so it was uh

exploiting that uh and was able to

connect to the network and then the

latest one is I think WPA 2 uh which has

fixed that so it is using uh like Advan

encryption standards so WPA 2 WPA 3 have

come up and like they offer stronger so

nowadays you like newer routers you

won't be able to easily track into them

all right fre so I'm done with my

networking questions uh just on a few

behavioral questions where I want to

understand how you would react to

certain situations and if you have

handled any of

these because you have you don't have

much experience you're just a fresh grad

just a couple of years how much did you

say how many years of experience you

have one year right uh nine months I

think

Ned in August 2023 okay yep so 6 months

to an year so if you do not know the

answers or if you haven't dealt with any

of these scenarios just yeah you feel

free to say that you haven't but if you

have any ideas so I'm open for hearing

so tell me a situation if where you had

to explain a complex technical problem

to a customer with limited

knowledge have you had such a experience

yeah yeah yeah so uh similar experience

I have had was

uh uh a team member but he he didn't had

uh technical knowledge like he uh he uh

he was in the uh uh different different

sort of like we can say department so

business analysis so we had to explain

him so what uh things I did was uh I I

tried to uh break break down the I tried

to break down the solution whatever we

were implementing so I had to break down

that and I I tried to explain him using

like examples like uh uh giving

different

analogies uh so yeah and iy I I tried to

like uh give him different different

examples like different approaches so

yeah that's

how that's how I I encountered this all

right uh any time where you had to

collaborate with a developer to resolve

a technical

issue uh yeah this uh this happens like

usually this happens so if there is some

task assigned to me and I I do not have

like uh understanding of that uh I would

connect with uh like fellow developer

who has like I would ask in team like

who has worked on this module or

recently been working on this so I can I

I'll connect with him over teams or if

he's present in office then we can like

sit together in a meeting room and then

uh I I asked him like how did he

encounter we just go to through the

debugging mode so whatever he has

implemented we can just go like assign

like have some debugging points and uh

we can go through the whole flow and I

ask him different questions like uh like

in the way I need to uh Implement that

solution so what challenges would I face

and yeah we can have that uh sort of

discussion and then I I get a clear idea

of how like how can I Implement uh like

how can I like develop that

similar thing okay all right now because

the cloud develops all these

Technologies they keep on changing there

is always some new content coming up so

how do you stay informed on the latest

advancements which are happening in

these

fields so yeah I rely on mostly like

social media like on LinkedIn or on

YouTube you get to see lest things also

you can uh you can follow newsletters by

uh like few uh recognized people uh in

the industry who are working there so

they they post their own experiences you

can also there are like different

different uh organizations have their

own engineering pages so like hot star

has its own engineering page like blog

technical Blog then Netflix has its own

technical blog so there we can get the

whole white papers we can uh read them

like what problem they have uh

encountered what like business problem

they were trying to solve which

Technologies they leveraged for solving

it

so yeah also like if we want it less

like less serious we can also watch

podcasts and all to like yeah stay in

Trend okay so one last question in this

interview so describe a time where you

faced a high pressure situation at work

and how did you manage the stress and

ensure that the tasks

complete yeah so this was uh like uh

when I joined organization a few months

back uh like I was assigned on my first

project so the thing was that I was uh I

thought that I was told to Shadow the

project like it was assigned to one of

the senior member in my team and I was

just looped into that mail so there was

sort of miscommunication I thought that

it would be just shadowing me shadowing

and he'll be developing the project and

I just he'll be updating on and I'll be

asking him questions but the thing was

that it was actually expected that I

would be developing the project and he

would be just guiding me so there was

sort of miscommunication so it caused a

delay so and then I realized that whole

thing needs to be developed by me and

there was like short deadline so uh the

thing I did was like uh prioritize that

task so I I started focusing on the

single task like uh to deliver it uh

within the ETA uh so I took help of him

I like help in the way like I If I had

like I didn't understood the module like

what was the existing functionality

where like s where is the similar

functionality implemented so I can take

reference of it uh so he helped me in

that way like guided me and so I started

working on me so between I got into many

issues so at that time also I took his

help also I took like few other members

help to solve that issues like how can

this be done so asking lot of questions

that was my Approach and just not

stopping just I was just going on going

on so it was like a good experience I

would say because after handling that

stress uh during that stress it was like

painful I was thinking that what where I

have come but after completing that

project and after that project went into

production and all I like felt more

confident like if I can handle this like

I can do it in small time then I can do

like a lot more complex uh things so

even my lead started to assign me on

complex projects after that so yeah that

was my experience with uh like handling

stress cool all right thank you pram I'm

done with the interview and uh so I'll

be providing you a little bit of

feedback after I pause the recording but

thank you for your time today yeah thank

you sir thank you
