Mostly there were problem solving questions and questions depending on your resume. I recall the following questions: 1. Given a linked list containing 0s and 1s rearrange it so that all 0s come before 1s..... O(n) 2. Given a binary tree find the max diameter and the two end nodes of it. 3. Delete the kth node from end of a linked list (single pass) There were some more.. That I don't recall. I work in NLP and ML. So they asked a lot of questions regarding my project and internships. So prepare your resume well..
