There were 3 rounds in the process.

First round included some Python coding, concept checking about agents and RAG and their coding as well.

Second round was leaned towards my resume and also I was given a use-case to design at high level.

Third round was a direct communication round with manager where he wanted to understand my thought process and vision. We also discussed about some possible conflict scenarios and how I would solve them.

Some questions that I am able to recall:

1. Assume that you have a large number of PDF files present with you (around 10k-15k) locally. Write a program to parse the first line of all of these files and as output, provide a concatenated string of the first lines of all of these files separated by a comma.

The interviewer asked me to make the code extremely efficient.

Further asked me why I can/cannot use threads or process here

1. Suppose that you have two vector stores, given an input user query, write a code in LangGraph that uses the result of these two vector stores and generates the output.

Asked to add enhancement: Only retrieve from second vector store, when the first vector store returns < 5 documents

1. Suppose there is a family planning a trip to San Diego, how would you design a door-to-door service in this case.
