Had an initial phone interview with the manager. He asked a lot of networking, synchronization, C questions
Had a call for on site interview within a couple of days.
There was a technical test to start with.
After that had an 1-1 interview with 4 interviewers.
All the interviews involved coding on data structures. The other parts of the interviews consisted of questions on synchronization, networking, past projects etc.
Overall a very good experience.
