First interview was a phone interview with the potential manager. Questions are mostly technical question like how does tcp work? what are two factors authentication? how does ping work? I was called for a second face to face interview and it the interview was 30min each with 5 people. All were techniacl interview and questions are mostly about penetration testing and malware in the wild.The downside is they did not account and give you time to take a break. I told one of the interviewer that i need water but i was ignored. the interview was one sided, they did not give you time to ask them questions so you will not get the feel of how they work.
