I had four rounds of technical interviews.

The first round involved writing code for a couple of problems. They weren't too tough. You were expected to walk the interviewer through your code.

The next two rounds focused on different areas of my technical domain: servers and request handling, and core Java concept questions.

The final round was with the Project Manager for whose team I was going to work. Apart from questions on previous work experience, I was asked only one technical question. I was expected to answer with the algorithmic approach to the solution, in a more language-agnostic manner.

There was at least one puzzle question asked in all the interview rounds. I had solved many puzzles in the past, so I already knew a couple of questions. The other two were completely new to me. The interviewers seemed quite affable and a bit lenient. They waited patiently as I solved the problems or puzzles.

First round interview question: Write a JAVA program to print a matrix as a spiral.
