Bloomberg Senior Developer interview questions

Lots of tedious online tests before even getting to a phone interview - which was itself another interacitve computer test. It seemed like a lot of trouble considering the job. I find it kind of funny companies like Bloomberg (& Google & M$ et al) go so crazy for difficult interviews for what are basically run-of-the-mill IT jobs.

Screening through a recruiting agency over the phone, then one phone interview and a visit to NYC to be interviewed by 2 different teams of 2 people each, 3 hours with groups of 2 people, for a total of 12 people, the interview lasted all day, they paid for my plane tickets and hotel. I learned that both teams wanted me when the recruiter called me next day with the job offer.
