I was told that they would conduct 4 or 5 rounds.

1. An initial round of HR - Your background, your expectations, etc.
2. Technical round - Algorithms and a few questions on Python concepts.
3. Technical round - Completely Python.
4. F2F - Which they said I was shortlisted for, but never happened.
5. HR/Behavioral, maybe.

1st Technical Round: Write a binary tree program in Python. Explain what decorators are, and the difference between generators and iterators.

2nd Technical Round: Write a Python program for Fibonacci, improving performance based on increasing input. Write a program for n^m, also improving performance based on increasing input.

3rd F2F: They said I was shortlisted and asked for my availability. I was not available the immediate week since I was traveling and offered to reschedule for a Skype call. However, they insisted on F2F, for which I was available a week later. The HR kept telling me she was working with the panel members on it, but after three days, I received an automated email stating the position had been filled.
