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. He asked to write a function to detect loop in a linked list. He also asked about malloc return type and calloc v/s malloc.

3. Third manager asked about searching algorithms and their complexity.

The bubble sort algorithm is used.
