Round 1:  

Round 1 was an online test on Cocubes platform.It consisted of 30 aptitude questions to be done in 30 minutes. The aptitude questions were mostly data interpretation based and we were extremely short of time . You have to be selective because solving all questions was not possible. There were 10 quantitative questions too which were moderate in difficulty, mostly from permutations, speed distance time, trains etc.. Part 2 of online round consisted of 2 coding questions to be done in 30 mins. They were different for everyone. They were of easy to moderate difficulty level. My questions were:

1.Reverse a linked list in groups of size k
