Material/links useful for interview

I faced quite a few interviews for summer internship and out of that experience I came up with some good material which is worth reading.

http://www.careercup.com This is good for any company interview. Its like forum where interviewees put thr qs. SO its like question bank for each company. You can sort by company and type of question also.
