I applied through a recruiter and the process took 3 weeks - interviewed at Bloomberg L.P. in January 2013.

Interview Details – Got the opportunity through recruiter, followed by 2 1-hour technical phone interviews with 2 person team each time. On site interview was setup in NYC. They have a mass interview setup with tiny glass cubes where everyone can see you , it was weird looking at other interview candidates in next 3-4 cubes and hearing them too. They have free food and a cool atmosphere right in manhattan.

Software Engineer Interview

Software Engineer
Binghamton, NY

I applied through college or university and the process took 5 weeks - interviewed at Bloomberg L.P. in October 2012.

Interview Details – Bloomberg came to my school's job fair, where I handed in my resume. From there, they contacted me for an on-campus interview, then a second interview the next day, then a third and final interview the following week. The first two were technical, and the last was with two HR ladies and lasted only 10 or 15 minutes. After that, I didn't hear for a few weeks, which could be explained by Hurricane Sandy messing things up, I suppose. I ended up not receiving an offer, which befuddles me since I had three rounds of interviews.

Interview Question – We're playing a game of Russian Roulette. I take 2 consecutive bullets out of the 6 bullet revolver and spin the chamber. I go first and shoot the bullet at my head, which misses. I then pass the gun to you, where you have the option of spinning the chamber, or shooting. Which would you do to maximize your probability of not dieing?   View Answers (5)

I applied through a recruiter and the process took a day - interviewed at Bloomberg L.P. in November 2011.

Interview Details – Had a phone interview set up by a recruiter. Worst interviewer I have ever experienced. Asked really basic questions like, 'What is a class?', and 'What is polymorphism?' and if I didn't give him the exact answer that he wanted in less then 10 words he would get haughty and short with me. I should have ended the interview myself he was so arrogant and ignorant. Will rate the interview as difficult because knowing the canned response to his basic questions was impossible.
