The entire process was well organized and very technically oriented. They were hiring Python developers. The first round was telephonic, and I was asked too many questions outside of my work areas. Though it went below par (according to me), I received a call for F2F interviews.

There were three more tech rounds.

• The first round covered the basics of Java, Python, programming skills, my experience, and work areas. I was given two to three sheets of paper with Python questions. Then, I was asked to write a program in Java on paper (not a coding round).
• The second round was purely a Java round. I was asked about stacks, queues, and their implementation under different conditions.
• The third round was to check my resume. They asked about each and every word on my resume.

After the tech rounds, there was one managerial and one HR round.

In the managerial round, I was asked to write a piece of code to implement threading, stacks, etc. The HR round was normal, asking "Why are you leaving your current employer?" etc.

Throughout the process, they made me feel comfortable, and the difficulty was above average.

Implementation of a thread-safe stack with memory constraints. (Managerial)

Discussed Big and Little Endian, prickling and unprickling, network topology, and reversing a linked list. (Telephonic)
