Round one had two coding questions, one was based on hashmaps and matrices (30 minutes), and the other was about combinations (20 minutes). Both were not too difficult, but the time constraint was a problem. They were scenario based questions. There also were technical aptitude questions and quants, about 25 of them in total. Since they had negative marking, I did not attend a few questions, and was able to pass 3 test cases in the 20 minute question, and was able to complete the other question. Got selected to the next round, which was the technical interview. Questions were: Boundary traversal of a tree, Kth last node in a Linked list, Searching in a sorted, rotated array, heaps, and a bit about my projects on my resume. Didn't do well in this round because I panicked. But it was average overall. They expect you to know a lot beyond your curriculum.
