I got referred to my manager by my PhD advisor. I had only one phone interview. The interview was around 45 minutes and I was told that I will get the offer. The interview was more like an introduction to my job by my manager and a summary of my background by me.

The interview took 1 day. First a written round of programming was taken off 3 questions:- 1. Program to swap 2 numbers without 3rd Variable 2. Program to reverse the items of a Linked List. 3. Program for Inorder Traversal Then 3 interview Rounds with 3 different managers were held:- 1. First manager asked about family background. Then, he asked the algorithm for square root of a number. Another question was if a file changes on client side, what can be the ways to trigger something on server side. 2. Second Manager asked about sorting. Asked to write a function to detect loop in a Linked list. Malloc return type. Calloc v/s malloc . 3. Third Manager asked about searching algorithms and their complexity.
