After you send your resume, you will get a email to do some coding and send back the result in 1 hour. The question is about sorted linked list merge and merge sort linked list. After that you might have 1~2 Skype interview. Each one you should answer 2 coding question and discuss your background. For me the coding question are convert sorted linked list to BST, recover the linked list which has loop in it, regular expression for IP, array implementation of queue. Nothing to tricky. After that I went to the onsite interview. And I meet 8 people that day, including 2 co founders. The question are in a very wild range that you cannot expected. Compression Unicode, UDP TCP comparison, Linux kernel .... I realize there might now be NCG position, unless you are a rockstar. GGGL.
