Rippling Software Engineer interview questions

First there was a coding round of 90 minutes consisting of 3 questions 1 was easy 1 was medium and the last one was on segment tree if we go for optimal solution. Then there were Interviews round.

It was an on campus oppurtunity with 6m+FTE. First round was an online coding test with easy to medium difficulty. Questions were mostly graph based. Next the interview had 2 rounds, both eliminatory. The first round was completely DSA based. I was not able to memoize my answer correctly and thus I was out. The interviewer was not very interactive and I had to force the interaction. What I heard from others, second round was mostly object oriented design(eg LFU) and basic DSA.
