On campus Career fair - submitted resume. got a call the next day for on campus interview. There were 4 technical rounds. all on campus. after 5 days got a call with an offer.

Interview Questions
  • mostly all questions were based on data structures and algorithms. expect atleast on brain teaser if you clear the first round of the interviews.
    Questions to me were- sorting an arraylist containing 1's and 0's. how to implement LRU cache. How would you implement an auto-complete feature. encoding a word file to save space- any ideas?

    Interview Details

    Got a first round interview through school career fair. First round interview was technical from the start, asked for a brief introduction about myself and then went straight to coding. Given a piece of paper and asked to code live. Mostly data structures questions and anything you said to have known on your resume. So hopped from topic to topic based on what you had down as knowing. Second round also very technical was almost 3 hours in nature and very intensive.

    Applied online on their website. The process is pretty streamlined and straightforward. I got a response within a week asking for open slots for a phone interview. The 1-1 interview started with an introduction, talking about one of the challenges from the activities on your resume. Then a couple of theoretical questions about data structures (differences between them, implementation etc). The interviewer was friendly and kept prompting towards a possible solution. I felt that they want to guage how you communicate your ideas since that's what you'l be doing on their team. This was followed by a small coding question, not a lot of emphasis on the 'include's etc. rather they want the code. You should discuss your ideas with them, ask questions, use examples and write the code. It probably won't be perfect so they'l prompt you to find the bugs. That was followed by a couple of other questions on algorithms and then a section for your questions. Feel free to ask them good questions.

    I applied through college or university – interviewed at Bloomberg L.P..

    Interview Details

    Got a phone interview after speaking with a recruiter at school career fair. The interviewer called 20 minutes earlier than the scheduled time. I did not have my laptop ready with me (I was told in the email that the interview would be done using codepair.com), so I politely asked him to call me at the scheduled time. And then he called 20 minutes later than the scheduled time. OK. that's fine with me. BUT, the entire interview was full of random easy questions. He asked me to write code on the paper and read it to him. And when I showed him my solution, he said "Why don't you use XXX? Have you not learned it?" But that problem can be solved using same time complexity in my way. :< It sounded that he was in a rush because he was super impatient and interrupted me several times when I was talking. It is by far the most negative interview experience I've ever had. And the moment I felt I was treated unfairly, I stopped anticipating the result because I don't think I'll take the offer even if I get in.

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

    Interview Details

    Had a phone interview and was contacted the next day to come onsite 3 weeks later.
    Phone Interview
    Basic questions on C. (Stack, Heap, Memory management, pointers)
    Algorithm questions(Hashtable vs Binary trees, Linked lists), how to implement hashtable

    Onsite Interview
    Interview One
    Q1 Josephus problem
    Q2 Find all anagrams of a given word in quickest way possible

    Interview Two
    Reverse a linked list

    I think the 2nd interviewer had already made up his mind even before interviewing me. I solved the problem corrected. He took a quick glance at my solution and said "thats all for now. Your recruiter will contact you in about a week"

    I knew it was over because the onsite is usually 3 to 4 interviews.

    I applied in-person – interviewed at Bloomberg L.P. in October 2014.

    Interview Details

    I submitted my resume on a campus event and got an interview opportunity very soon. The whole interview took 1 hour. Most questions are technique questions about algorithm. The questions were not difficult. They were basically related to data structure or OOP. I needed to write the working code on paper. This was a bit difficult to me, because I needed to ensure everything was organized before I wrote them down. The interviewers are patient and nice.

    Phone Interview was simple. He asked me about the my projects and questions on Linked List. I believe that he did not have any idea on that. And few questions on arrays which I screwed up.

    I applied online. The process took a weekinterviewed at Bloomberg L.P. in October 2014.

    Interview Details

    Applied online. 3 one hour on-campus interviews in successive days. Questions not too hard, but mainly technical. Started with a pair of recruiters giving questions together. The next day, there was only a single recruiter, but similar to the first day. The third day was a little similar, but with a project manager for the first half. The second half was mainly HR related questions with the R&D recruiter.

    • Assume you have a large file with lines of timestamps and IP addresses. Timestamps are ordered, but may repeat and may skip. How do you determine whether there is a time window that has a certain IP address appearing more than k times? How would you solve this if instead you received a stream.   View Answer

    I applied online – interviewed at Bloomberg L.P. in October 2014.

    Interview Details

    I applied online and they contacted me after 3-4 weeks asking me to give various available time slots for the phone interview. They scheduled a 45 minutes phone interview.
    Choosing a programming language of your choice:
    How do you implement a Polynomial?
    After I told them Array list, he showed me a very big polynomial and asked me what will you do if you have very big polynomial that needs to be handled? (Using an array list 'll consume hell a lot of memory for polynomials of higher degree)
    I answered him that i 'll use a hashmap to store the degrees and coefficients. He seemed to be impressed with that.

    How will you implement the following four functions using the hashmap/arraylist:
    1. Constructor which details how your polynomial is stored
    2. Adding two polynomials.
    3. Printing polynomial.
    4. Finding the derivative of the polynomial.

    He also asked me about my prior work experience and also about my current Master's thesis project which I thought I answered well. But I was able to implement only the first two functions(using arraylist) with in the time limit. Got a rejection email with in 3 days.
