Interview Details

Standard software engineering interview. Data structures, algorithms, problem solving. Try to tell good engaging stories of how you solved a difficult problem using a technical solution - I think this is what they were impressed with the most.
Offer was very good, overall stable company with a lot of work in the R&D department. Highly recommended.

    I applied online – interviewed at Bloomberg L.P..

    Interview Details

    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.

    Interview Details

    Had one technical phone interview. We also used HackerRank to share an IDE screen. I was asked a series of questions about bash and c++. I was given some example code or an example dataset and was asked to implement a solution or algorithm. I had no experience in bash so this interview did not go well.

    Application Details

    I applied through a recruiter. The process took 6 weeksinterviewed at Bloomberg L.P. in August 2013.

    Interview Details

    Bloomberg has a pretty intensive interview process. Met with two groups and both interviews lasted 3-4 hours. Met with teams of two developers at a time. Generally they probed for insights about different architectural issues and had you solve programming tasks. Interviewers looked for code to be written with pen and paper. The questions were challenging but reasonable and they were encouraging if you got stuck or missed something.

    Interview Questions
    • They asked for insights on architectures common to their environment and dealing a lot with scalability issues.   Answer Question

    Interview Details

    Had interview with them few weeks back

    My first round was simple DS/C++ problems
    1. How to get top 10 most traded stocks from continous feed of stock trade
    2. Implement a function so that it will not proceed with its operations if it is called more than 100 times per minute

    Second Round
    1. Implement Shared pointer
    2. Design a Web Service, where multiple feeds are input and they are trying to modify a common database

    Third Round
    They showed me Bloomberg Terminal. Asked very generic questions what were the most challenging moments in your career. How do you plan your work? Few questions around the background.

    After this I met with HR and he said entire team is really positive about me.

    Fourth Round
    Interview with the senior manager. Showed me Bloomberg Terminal again, I kept asking him all the queries I had around the terminal. In the end he said you asked really good questions

    HR Round
    He said people are very positive. Discussed salary expectation and all the benefits Bloomberg provides.

    Round with Head of the Business unit
    He was not sure that I had all the technical rounds before and asked me very basic programming questions
    1. Error in the code
    2. Difference between 32 bit and 64 bit systems

    Few behavioral questions, Why Bloomberg? Why we should hire you?

    After this HR told me that people were really positive and he will send me salary breakup next day. I didn't received any confirmation from them for a week and later found out that I was not selected. This is really unusual of Bloomberg as they respond within 2 days. I answered their each and every technical question, I really don't know what they expect.

    Overall a good company with weird people.

    Interview Details

    Phone screen followed by onsite interview with couple of FOB types. Asked all kinds of minutia about C and C++. Interviewers were very rude. I had more experience then them in various areas so they seemed to be trying to take me down a peg. Didn't get any time to ask about the role.

    Interview Questions
    • Dig up the C++ faq and memorize. That's the only way to please these types. Even then look to be disqualified if the think you might potentially get into a lead position.   View Answer

    Couple telephone interviews - first with HR and then a tech screening. Pretty strong interview for finance technology company. Know your CS basics - even if you've been out of college for 10+ years. Big O of sorting algos, data structures (how they are implemented, etc.), what is the vtable in c++, etc.

    Interview Questions

      Picture a restaurant kitchen with tickets of customer’s orders which has a start time, end time of when the order was completed, and price. How would you find the longest contiguous time that tickets were processed within a given day?

      Input is an unordered vector.
      First sort the vector - which sort? What is different between quick/insertion/merge/etc.?
      What would be your algorithm? Do you loop through the vector?
      What would be the variables you store?

      (2)
      How would you build an index for a given book?
      What data structures would you use?
      What algorithms would you use?
