The first interview is with an HR person. She asks a lot of basic CSC questions. Most of them can be found here, like how to delete a row from a table and the kill command for Linux. The next interview is a 45-minute to 1-hour phone interview. He asked me why Yelp, what is one thing I would change about Yelp, and how to go about implementing that change. My coding question was: You have a single linked list with two sorted parts. Each part could be a different size or be of size zero. Interchange the two sorted parts. He wanted a constant space solution: a1 -> a2 -> .... -> an -> b1 -> ..... -> bm would become a1 -> b1 -> a2 -> b2.....

Typical interview.
