These are representative of what Hyderabad employers — from services firms to product companies — actually ask. For each, we give the question and a concise model answer.

Frequently Asked Questions

What are the fundamentals an interviewer expects for Generative AI?

Solid command of LLM fundamentals, Prompt engineering and RAG pipelines. Interviewers probe whether you understand the *why*, not just the syntax.

Explain a project where you used LangChain and LangGraph.

Use the STAR method: the situation, the task, the actions you took with LangChain, and the measurable result. Concrete numbers beat vague claims.

How do you debug a problem in production?

Reproduce, isolate, check logs and recent changes, form a hypothesis, then verify with the smallest possible test. Communicate clearly throughout.

What's a trade-off you made and why?

Pick a real one — speed vs accuracy, cost vs latency, simplicity vs flexibility — and explain the reasoning. Interviewers want to see judgement.

How to structure your preparation

  1. Revise fundamentals: LLM fundamentals, Prompt engineering and RAG pipelines.
  2. Build two projects you can discuss for ten minutes each.
  3. Do timed problem-solving and at least three mock interviews.
  4. Prepare your STAR stories before the interview, not during.

Common mistakes candidates make

  • Jumping to code before clarifying the question.
  • Memorised answers that fall apart under follow-ups.
  • Going silent — interviewers want to hear your reasoning.
  • No questions for the interviewer at the end.

Be ready to write clean, readable code on a shared screen — like this:

# Minimal RAG: embed, retrieve, then answer
from langchain_community.vectorstores import Chroma
from langchain_openai import OpenAIEmbeddings, ChatOpenAI

store = Chroma.from_documents(docs, OpenAIEmbeddings())
context = store.similarity_search(question, k=4)
prompt = f"Answer using only this context:\n{context}\n\nQ: {question}"
answer = ChatOpenAI(model="gpt-4o-mini").invoke(prompt)
print(answer.content)
