Capgemini Sr Software Engineer interview questions

Interview was scheduled in weekend for coding round. Was given one question to solve in coderpad. Interview asked Time complexity and space complexity for the solved question and asked me if i can solve the question using while loop instead of for loop.

I got a call from capgemini for interview in July. They asked for my current and expected salary. I cleared the interview. Then after the interview they asked for the salary expectation again. Then they didn’t reply for 1 week and after that when i tried to reach they said that the position is on hold. I got call again in August saying for interview again I cleared the interview again, now the position is again on hold. They are just wasting our time and efforts. Worst experience
