I applied through a recruiter and the process took 3 weeks - interviewed at Bloomberg L.P. in December 2010.

Interview Details – Was contacted by phone. After initial phone screening having standard riddles and algo questions, I was invited to an on-site interview. There were many interviewers asking a lot of questions and didn't let you finish, constantly switching from one question to the other. Took about 7 hours. Overall it doesn't seem as a good place to work at.
