Druva Pune Interview Experience

Recently I got a chance to give interview at druva Pune. They ask some decent interview questions. I am going to include all questions that were asked to me and my friends.

They follow the same interview process : 1 coding round + 1 telephonic + 3 Technical + 1 Hiring Manager + 1 HR

Questions asked in different rounds in random order ->
