I applied through university. The process took 2 weeks. I interviewed at Tripadvisor (Amherst, MA) in Oct 2013
Interview
Phone interview with coding on online whiteboard. First he asked about hash table and hash function, then he ask if there is any other kind of data structure that can give the same index function. I gave the answer of prefix tree but he said any kind of tree is ok there.
Next question is about linked list: how to find the node that is odd, how to delete these nodes, providing the code in the online whiteboard. I gave him the code but he pointed out some corner cases that my code did not cover. Then he asked if I had any question. The whole process is about 30-40 minutes.
Interview questions [1]
Question 1
Not really sure about the index data structure. I thought only array or hashtable can give the direct index to access. Still don't know why tree can give the same kind of indexing as hashtable.

Interview
I applied for this company on our campus career fair, and in the next few days they scheduled me an on-campus interview. One person interviewed me for about 45 minutes. Only technical questions, didn't ask me about my project or something else. He asked me to write code in a white board and then asked me some question about the code.He also told me there would be 3 rounds of interviews.
Then I received an email telling me I passed the interview and then came up the 2nd round - telephone interview. It's a 30-minute interview asking a quite simple question and some extensions. Then he started to introduce the job and environment of their company.
And after maybe 2 weeks, there will be an on-site interview if you pass the previous one.
Interview questions [1]
Question 1
Nothing difficult. The first question is about combination of HashMap and ArrayList, which the best answer should be LinkedHashMap but it's OK if you didn't know about this class.
The second interview is to find the same element in two lists

Interview
Two phone interviews covering:
1. Find and remove all numeric characters in a singly linked list
2. Questions about basic data structures, trade offs, use case, access complexities
3. Given string A, B, return string A - (A intersect B)
4. implement basic hash table and collision handling
5. Discuss algorithmic complexity of solutions in all cases

Question 1
Nothing unexpected. Very standard cs101 data structures related questions.
