Ultimate LLD and HLD Roadmap | System Design RoadMap | LLD & HLD Topics to be covered for Interview

Summary

In this video, Shreyash Jain outlines the roadmap for his 'Concept Encoding' playlist, focusing on low-level design (LLD) and high-level design (HLD) for system design interviews. He emphasizes the importance of understanding OOPs concepts and SOLID principles for LLD, covering 23 design patterns and their application to interview questions. Jain also discusses the future content, including 'Split Twice Simplify Algorithm' and various system design components like microservices and caching. He invites feedback for improvement and announces an upcoming Spring Boot playlist, promising comprehensive and free system design education.

Takeaways

• 😀 The video is aimed at both newcomers and regular followers of the channel, focusing on system design.

Q & A

What is the prerequisite for learning low level design according to the video?

The prerequisite for low level design is a solid understanding of OOPs concepts such as inheritance, polymorphism, and abstraction.

Why are SOLID principles important in the context of low level design?

SOLID principles are important as they provide a foundational understanding of object-oriented design, which is crucial for tackling low level design problems.

How does the video presenter approach teaching design patterns?

The presenter teaches design patterns by covering a few important ones and then solving related design problems, rather than covering all 23 patterns and then moving on to questions.

What is the significance of the green tick marks and question marks in the video?

The green tick marks indicate that the design patterns have been covered, while the question marks represent topics that are yet to be covered in the playlist.

Can you explain the teaching method the presenter uses for design patterns and interview questions?

The presenter uses a method where they cover important design patterns and then solve interview questions that can be directly addressed using those patterns.

What is the presenter's approach to selecting which interview questions to cover?

The presenter selects interview questions based on their frequency in top product-based companies and includes questions submitted by viewers, ensuring the content is relevant and practical.

Why is 'Splitwise Simplify Algorithm' considered important in the video?

'Splitwise Simplify Algorithm' is important because it is a common interview question that tests the candidate's ability to handle complex algorithmic problems from a low level design perspective.

What does the presenter mean by 'the sequencing of the videos' in the context of the playlist?

The presenter refers to the order in which the videos will be released, which may change depending on priority and viewer feedback, but the teaching pattern will remain consistent.

How does the presenter plan to handle the difference between low level design and high level design in terms of content delivery?

The presenter acknowledges the difference by structuring low level design content in a sequential manner without chapters, as there is no one correct answer, while high level design requires learning specific concepts before solving questions.

What is the presenter's stance on providing free system design education?

The presenter is committed to providing free, high-quality system design education, as evidenced by the depth and breadth of the content, with the goal of making system design knowledge accessible to all.

What new initiative is the presenter working on, as mentioned in the video?

The presenter is working on a Spring Boot playlist, which will be launched after outlining the sequential content, aiming to further assist viewers in their interviews.
