2-3 Hour programming exercise in their office. The exercise included some debugging, some data structures knowledge and some bash scripting exercises.

Following that there was a face to face interview, where you are asked some programming questions, and then an HR interview

There were mostly 3 programming questions:

1. Populate an array with 1-n numbers, with no repeating instances.
2. Given an array of n-1 numbers, populated by 1-n numbers, find the number that is missing.
3. Given two linked lists that are connected, find the common link between the lists.
