Financial Software Developer Interview

Financial Software Developer
New York, NY

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

Interview Details – Drop resume at university career fair, schedule an one-week-later school campus interview right on the career fair after chatting with the representatives; the second week, 2 rounds interviews with 2 Bloomberg employees each in the same time, all technique questions; then got an invitation for an on-site interview with a technique manager, followed up by an HR representative. The onsite interview is technique too, they also ask why you want to work here and show you Bloomberg terminal. Got an offer a week later.

Interview Question – Seems there's a stress test during one of those interview in which they ask you an open ending question and pretend not satisfy with your first answer. Just keep calm and keep talking.   Answer Question

I applied through college or university and the process took 6 weeks - interviewed at Bloomberg L.P. in October 2012.

Interview Details – The process started with visiting the Bloomberg LP booth at my university. I gave them my resume and we discussed a project or two. I then asked if they were doing interviews on campus and they told me yes. Before I could get a campus interview, I had to answer a few questions at the booth. These questions were brain teasers and C++ specific language questions. Upon impressing the recruiters at the booth, I was offered the on-campus interview.

Next, I met with two campus recruiters about a week or two later when they were in town. It was a technical interview with a few HR undertones to see if I had done my research. Questions were mostly based on system architecture: "how would you design a stock tracking system...?" and data structures: "how would you implement a queue using only the stack data structure?"

A couple weeks later, I heard from an HR representative who invited me to an on-site interview. They flew me to New York and I stayed in a hotel the night before the interview. I got to Bloomberg Tower at 10:30 am and the interview was at 11:00 am. You will be asked to check in at the front desk 15 minutes before your interview. You will have your picture taken and they will print a visitors badge for you. Then you will go up to the sixth floor and wait for your host to come greet you. My host came for me a couple minutes later and took me to a conference room on the 23rd floor of the building. The view was phenomenal. I had a fantastic view of Manhattan and Central Park.

The first interview was 2-on-1. One of the interviewers was a project lead and the other was more fresh. They started with the some questions about me and my resume. I got to tell them about my favorite project and show some enthusiasm for my work. Next they asked some technical questions. Specifically the questions were algorithms and data structures questions.

The next interview was 1-on-1 with someone more senior. From what I gathered he was a team lead - mobile development if I recall correctly. His questions were very direct and he made it clear that he was not trying to trip me up or ask me trick questions. He was very blunt but it was one of the best interviews I have had because the pressure was on and I had to think on my toes. His questions were of an HR nature mostly. The toughest and most surprising question he asked was "There are many large companies with many of the same things to offer as Bloomberg LP in the city, eg Google. If a friend was there and mentioned they had opportunities available, would you pursue an opportunity there?" See the answer below. After the HR questions, the interviewer asked me a number of coding questions ie find the bug in this code.

The last interview was strictly HR stuff - including the dreaded "do you have any expectations with respect to compensation?" I used some of my knowledge from this website to answer with a range and tell her that I expect at least the average salary to be competitive. The HR interviewer said they routinely offer higher than the number I requested.

At the end of every interview I was given the opportunity to ask questions.

I heard from HR in only 3 business days with an offer.

Interview Question – There are many large companies with many of the same things to offer as Bloomberg LP in the city, eg Google. If a friend was there and mentioned they had opportunities available, would you pursue an opportunity there?   View Answer

Negotiation Details – They gave me more than a month and a half to accept their offer. I have yet to negotiate and I probably will not - given that their offer was better than I was hoping for.

The process took 2 weeks - interviewed at Bloomberg L.P. in February 2012.

Interview Details – 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.

  • 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.   View Answers (4)

The process took 4+ weeks - interviewed at Bloomberg L.P. in December 2011.

Interview Details – After applying through Bloomberg's website, I received an email about a week or two later saying that I had made it through a round of resume screening and I was asked to take an online skills assessment test. This test consisted of basic IQ sort of things (shape rotations/reflections), or things you might see on the LSAT exam (given 8 statements, what order did the horses place in a race?)

2-3 days after the IQ Test, I was asked to set up a phone interview which took place the following week. Because I don't have a computer science background, they asked "Get to know you" type questions about my past experience, and then asked targeted questions that are basically round-about ways to get you to consider computer science problems.

Within a week I had been asked for an on-site interview, which I went to a few weeks later. This interview consisted of three stages. In the first, I met with three interviewers who asked me questions to gauge my understanding of algorithms and high level design, and they asked me to write down a program in full syntax for the language I had the most experience in (Java). In the second round, I met with a senior member and he asked questions to gauge my interest and fit with the company, as well as to gauge my ability to transition into an IT position from an engineering background (What makes you think you would be happy doing this type of job every day when your experience is primarily in research?) The third and last round consisted of meeting with a man from HR and he asked very general questions, then gave me a super-brief tour around 2 floors of the building.

Interview Questions

  • How would you go about designing Facebook's "Suggest a friend" feature? How would you choose WHICH people to suggest as friends?   View Answer
  • Write a java program that can convert a string of numbers (e.g. "5387") into an integer (5387).   View Answers (4)
  • One question to see if I could understand Linked Lists and how to manipulate them, having never heard of them before.   Answer Question

Negotiation Details – I did not negotiate. I saw the salary range that had been posted on this website and thought it was fair, so I accepted it.
