I was recently interviewed for Virsec Bangalore. The initial interviews went great, the subsequent rounds were Data Structures and Algorithm questions as others have mentioned. The interviewer wasn't very professional when I wasn't able to come up with the solution he desired. Apparently the interview process here is them Googling top questions from leetcode and expecting you to solve it. Anyway, I still considered by experience as neutral and not negative but turns out these people will keep on calling you to schedule interview but they ghost you if you don't get selected. This is highly unprofessional, and looking at Glassdoor experiences , others have faced it too.
