Interview Preparation Tips

Round: Test
Experience: Questions were based on C concepts, given piece of code, find error, output, etc then data structures, bit manipulation, a few aptitude questions were also there (around 5-7).
Tips: Practice aptitude, C, data structures (geeksforgeeks.org is a good source).
Duration: 1 hour
Total Questions: 30

Round: Technical + HR Interview
Experience: I was asked to explain project in detail, I had done projects on embedded, so was asked about that, details like what fields did you use in that structure, why this implementation and not some related other. Memory management, network communications, operating systems. Then questions on C concepts like memory allocation, function pointers, then data structures like linked lists, then bit manipulation in registers. Questions from electrical coursework. Then later, why higher studies, would you still go for higher studies if you had a good job at a company, why etc.
Tips: Be thorough with C (know your Kernighan & Ritchie) and be prepared to go into details about your projects.
