Tripadvisor Software Developer interview questions

I was submitted through a recruiter. First round was a technical phone screen over collabedit, focused on algorithms and SQL. Also many trivia questions on data structure, algorithmic, and database performance, as well as knowledge of statistics/ML. The next round was a take home assignment on a common machine learning/prediction problem, which can be completed in any open source language of your choice.

I had a phone interview so far, but am continuing to the second round interview. The interviewer was very nice, and understanding because I had gotten back from an all night bus ride from a hackathon just half an hour before the interview started (at 9 am!)
