I applied online. The process took 3 weeks. I interviewed at Bloomberg in Sep 2010
Interview
I had an online C++ test, followed by a telephonic interview. Online test had lots of multiple choice questions , almost all C++ syntax and pointer related. Telephonic interview was good again mostly about C++, quiet interesting questions about V-tables, polymorphism etc. During the in person interview I was asked a couple of algorithm questions not too difficult.
The process took 2 weeks. I interviewed at Bloomberg (New York, NY) in Feb 2012
Interview
I applied to the position online, thinking it would go nowhere like all my other online applications. I got an email a couple days later asking me to take an assessment test (it was basically an IQ test). The test was about 30 questions, 3 minutes per question (it was timed per question) and the questions ranged in difficulty. I certainly didn't get all of them right, far from it. After that, I got an email asking me to set up a time for a phone interview. I responded, and then 1 week later they came to campus for a career fair. I went up to them and mentioned that I'd already begun the process online, and they took over the process from there. I interviewed 4 times within a week of approaching them at the career fair, and got my offer the following week. 3 interviews were technical, the last one was HR. The first two were knock-out rounds, and the last 2 were actually back to back, I went from the 3rd interview right to the 4th.
Interview questions [4]
Question 1
Say I have a deck of 52 cards, regular deck of cards. I put a joker in the deck somewhere and shuffle it up. Now I start dealing you cards until the joker shows up. Once it shows up, I stop dealing you cards. What is the probability that you have, in your set of cards, all 4 aces?
Can you cover an 8x8 chess board with dominos if two corner squares are removed (not two from the same side, 2 diagonal from each other). A domino covers 2 squares and no dominos can hang over the side of the board.
There is a panel containing 3 light switches in front of you. Each switch controls a light in a room somewhere. Doesn't really matter where. You can play with the switches as much as you like, but you're only allowed to enter the room once. How do you tell which switch controls which light? Again, you can only enter the room once, so you cannot play with the switches after you enter the room, but you can play with them as much as you want before you enter the room. One entry is all it takes to determine which switch controls which light.
