Interview Details

Company came to school career fair. Was contacted a few weeks after and was called for an on-campus interview. After the first interview, I was invited for another on-campus interview the next day (they flew from NY). Then I was flown to interview at HQ in NY and quickly thereafter got an offer.

    I applied online. The process took 5 weeksinterviewed at Bloomberg L.P. in November 2014.

    Interview Details

    I met the Bloomberg team at a YHack 2014, and was immediately impressed by the product. I applied that year, and received a phone interview, which contained mostly algorithmic questions. This year, I applied again, received a phone interview, and was asked questions questions of the same variety (difference between C++ and Java, difference between a BST and a hash table). They also covered some aspects of my resume, and asked me to describe a project I had worked on, some challenges I faced, and how I overcame them. I heard back that same week that I'd received a campus interview with them in New York, which I've yet to attend.

    Interview Details

    Had four on-campus interviews following a career fair--three technical and one with an HR guy. I was allowed to use any language. There were six questions. Two were about implementing some common function, such as a String class constructor. One required partitioning a list around a given element. One required merging two schedules that might overlap in some parts into one schedule. The last two are described below.

    Interview Questions
    • You're given a binary tree--not necessarily complete or proper--and you need to give each node a "friend" pointer that points to the node to its right in the tree. This node is on the same level but is not necessarily a sibling, which makes the problem a little tricky. The friend pointer of the node farthest to the right on each level should be null.   View Answer
    • You're given two arrays of the same size filled with positive integers, and an integer 0 <= N <= 255. You need to determine whether N can be written as the sum of some number from the first array and some number from the second array.   View Answers (3)

    I applied online. The process took 3 weeksinterviewed at Bloomberg L.P..

    Interview Details

    One 45 min phone interview followed by on site interview with three team members.

    The phone interview was quite easy. Standard technical C++ questions related to exceptions (what happens when a destructor or constructor throw one, what are virtual functions, etc). Nothing very difficult. He also asked what books about C++ and which important C++ people/blogs I follow.

    In person interview went well I thought. The first interviewer asked me to implement merge sort. The other question was to find k largest values in a very big vector efficiently. The second interviewer asked me to design an interface to a function (or a class) that finds a zero of a give function and he wanted to see the most general interface possible. The third interviewer, the guy who I had the phone interview with asked me about smart pointers and writing an exception safe assignment operator. All three were very nice and guided me through the process. I did stumble on few of the questions but eventually ended up answering all of them.

    Interview Questions
    • C++ template metaprogramming (that team was into functional programming and compile time computations). Standard, find nth Fibonacci number using recursive templates.   View Answer

    Application Details

    I applied online. The process took 4 weeksinterviewed at Bloomberg L.P. in October 2014.

    Interview Details

    Applied Online. Scheduled 1st phone interview within two weeks of applying. Scheduled on-site a week later. Heard back about an offer two days after the on-site.

    Very satisfied with the entire process. HR was fast and competent.

    Phone screen consisted of two questions on HackerRank. First question was coding a typical technical question. Second question was a design question, no code.

    Onsite was an onsite-day so there were many applicants interviewing at the same time (you still interview by yourself though). Four rounds in total. First two are 2:1 with engineers and very technical. You write code on pads of ~6x8 paper (wouldn't have been my medium of choice). 3rd round is a 1:1 with a senior engineer/engineer manager(?); no coding. 4th round is with HR.

    Interviewers were very friendly and willing to nudge you if it looked like you were getting stuck. They all seemed very intelligent which was a bit intimidating. The questions were also interesting and fun. First round was more algorithms and second round more data structures but that may have just been a coincidence.

    I applied online. The process took 6 weeksinterviewed at Bloomberg L.P. in October 2014.

    Interview Details

    I applied online near the end of August and they got back to me about 2 weeks later to schedule a phone interview. The phone interview was scheduled for about a week later. He asked a pretty standard interview question, and I coded it up online where he could see (I think it was on a HackerRank page). I thought they prefered C++, but he asked me if I wanted to do it in Java and I said yes because I'm more comfortable with that. I don't actually think that hurt my chances in any way. That question went fine, and then he asked me a few follow ups about scalability and bugs to check for. Then he went into some very specific C++ questions, which I stumbled through since I had only taken a semester of C++. Somehow I passed that interview and made it to the in-house. About a week later, my recruiter asked me which of 3 days I preferred to come to NYC and interview. A few days later they made travel arrangements. During the in-house interview, they give you a little tour of the office first then you meet with your interviewers and go to a conference room. Again, questions were very standard. You have to do them on a sheet of paper. The first interview there were 2 engineers, and they asked me 3 technical questions. I blanked out especially on the first question even though it was pretty easy. The second interview was just one person, and he asked me a fairly easy question, which I got right away and he said that was all he had for me so we talked for a bit before he let me out. Interviews themselves took about 2 hours total (but there's a small break in between). A week later, I got rejected--not unexpected considering I didn't do well on the first interview.

    I applied through college or university. The process took 2 daysinterviewed at Bloomberg L.P. in October 2014.

    Interview Details

    I applied through my college - 3 rounds of technical interview
    1st round : They asked me to select a data structure for storing a dictionary that i have to use for searching words with given letters.It is similar to that of SCRABBLE game.
    Passing a multi-dimensional array in c89 and other variations.

    2nd round : Design a class that takes any length integer (memory is the limit) given as string and implement constructors , addition by operator overloading (as i've told them about my choice of C++).

    3rd round : Write a code to find the common letters in two strings. He was more interested in how his input will break my code and how will i overcome it and what will happen at OS level.

    HR round: You have done some electronics stuff - arduino & stuff then why financial software developer?
    What are you top 3 priorities?
    What other companies you have applied for?

    I applied online. The process took 2 weeksinterviewed at Bloomberg L.P. in October 2014.

    Interview Details

    I applied online on a whim and got an e-mail response a few weeks later to set up a phone/technical interview. They hold technical interviews online through HackerRank. The interview began with three or four standard interview questions (questions about my resume, why Bloomberg, etc) which took about 5-minutes. The rest of the 45-minutes was all technical / algorithm stuff through HackerRank (see included questions). I struggled with the first (never really got anywhere) and then he told me to move on to the next one. Came up with an okay solution to the second one, O(n*log(n)), but he kept asking me if I could do it better. Ended up telling me a solution and then asking me to implement it (super simple).

    Overall, I felt like I was being grilled the whole time and it seemed like he didn't care about what I was saying unless it was me getting the questions exactly right. I know I didn't do so great on the interview. Got an e-mail a few days later saying they weren't interested in moving forward.

    Interview Details

    Took 2 weeks for the recruiter to call me and then a week later the interview was scheduled. Questions were easy c/c++ based questions but tricky in the sense that they were not logic based but relied on your level of preparation in that area.
