Process
1st round: HR interview. 2nd round: Online test. 3rd round: Phone interview, majorly on OS-related high-level questions. 4th round: Onsite interview.
For the onsite, it's basically easy data structures and algorithm problems. One relates to bug revision, and another relates to system design.
Get to know bit manipulation and iterators; this would help a lot.
