The first interview is with an hr person. She asks alot of basic csc question. Most of them can be found here. Like how to delete a row from a table, kill command for linux. The next interview is 45 min to 1 hour phone interview. He asked my 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 question: a1 -> a2-> .... ->an -> b1-> .....->bm would become a1->b1->a2->b2.....
