Tripadvisor Intern Software Engineer interview questions

Had on-campus interview, dove straight into technical question: Find duplicates in a binary search tree Had phone interview, straight to technical question as well given array of integers, implement class with array as member and function next() to return the next even integer in the array.

Started with an on-campus interview, had a phone interview second round, and went on-site for 3 questions. Interview process was highly technical.
