Krishak also explores frameworks, databases, and project implementation, encouraging viewers to leverage his channel's resources for effective interview preparation.
Takeaways
- 😀 The speaker, Krishak, shares insights from a successful student who recently got hired as a generative AI engineer.
- 📊 Interview preparation should cover a range of topics including Python, statistics, machine learning, deep learning, and natural language processing (NLP).
- 🧪 Basic to intermediate Python skills are essential, with practical tasks assigned during interviews to assess proficiency.
- 📈 Candidates should be well-versed in inferential statistics, particularly hypothesis testing techniques like Z-tests, T-tests, and ANOVA.
- 🔍 A significant portion of the interview focused on large language models (LLMs) and their applications in generative AI roles.
- 💡 Key NLP techniques such as text embeddings, including Word2Vec, should be understood, including how they are trained from scratch.
- 🧠 Familiarity with deep learning concepts like activation functions, loss functions, and optimizers is crucial for interviews.
- 🚀 The Transformer architecture, especially models like BERT, is heavily emphasized, accounting for about 30% of the interview content.
- 🛠️ Understanding open-source versus paid LLMs and the relevant frameworks (e.g., LangChain, LlamaIndex) is important for candidates.
- 📅 Real-world project experience in generative AI is highly valued, so candidates should prepare to discuss their own projects and deployment strategies.
