Entrevista
Bloomberg visited the career fair of my univ in Sept. I visited their booth and was asked some questions about resume and data structures like the intersection of two arrays. I was asked to give very specific description of how to solve the problem. I then was asked to apply on their website.
2 month later, I got an email for a phone interview. However, it was delayed by another month, because of Sandy. The phone interview is all tech questions about algorithm, data structures, and probability.
After a week, I was invited an in-house interview. Since I am in NY state, they refused to book me a flight to nyc and asked me to take bus.
The interview was in their headquater in manhattan. I faced 3 developers. And the questions were all technical. I failed in one brain teaser, so I didn't get inot the next round.

They had info session at school. I submitted my resume online and got the on-campus interview. The interview is 1 hour. Two engineers are the interviewer. Small talk at the beginning. Ask 1 or 2 questions about the resume. And then ask two technical questions. I finished the first one. But I did't have enough time to completed the second question. The first one is a string question. The second one is a tree question.

Entrevista
- There was one phone interview with a Bloomberg engineer.
- The onsite interview started with a so called tour of Bloomberg but abruptly ended with a museum of their colorful terminals. It was over in 5 minutes. The group of interviewees laughed a little when it ended.
- 2 rounds of technical interviews with a break of ~20 minutes. Found it easy. Mix of algorithm and design questions. All interviewers look satisfied when they left me.
- HR and recruiter forget that I exist. Forget to contact me for the next 40 minutes or so. I go to their front desk to inquire whether there are more rounds.
- HR appears slightly irritated but is polite. Next 30 minutes, HR tries to understand why after 6+ years of computer science education and working for a couple of years I "chose" to be a software engineer. Does not want to hear technical stuff. Had a hard time believing I could fit the role. I wondered whether I should have taken Psychology and then become a recruiter so I could judge potential candidates of a different discipline.
- At the end of the interview, was asked to "patiently" wait for the next round. Within 5 minutes, one more guy turns up and says the conference room is booked. Was once again asked to goto the front desk. Bloomberg office is huge and not all elevators goto front desk. :-( Reach somehow.
- Once again try telling the front desk people that I have an interview. Give the name of the host. Host appears after 15 minutes. Asks how the interviews are going.
I say "not that great". Asks whether - "Do you want to stay?". I lower my head and say "yes".
- In the conference room, realizes that the manager is out of office and the manager does not have my resume. Arranges a video conference. Asks the manager over conference to not keep him "busy" since he has a flight in flat 2.5 hours.
- Manager tries to understand how I ended up interviewing at Bloomberg and what role she could give me if I was chosen. It was nice but nothing productive. Interview ends in 30 minutes.
- Meet the so called organizer of the whole process. Asks whether the interview was awesome. I say it was "ok". Goes on a tirade on how people like me have a low attitude and should be happy to meet awesome people. After all, the process took only a day.
- Keeps repeating "Hope you get it". "Hope you get it" with a smirk while I collect my luggage and thank her for all the arrangements.
- Leave broken hearted and look tearfully at Lexington tower while I rush to the airport.
