Average Interview

Application

I applied online. The process took 6 weeks. I interviewed at Bloomberg L.P. (New York, NY) in March 2017.

Interview

I applied online back in Feb 2017. Received an email to provide availability for phone interview after a week. The phone interview was scheduled for 2 weeks later. It went well but didn't receive any email for a week. Contacted the recruiter and was told that I was invited for the in house interview. Due to weather conditions, my onsite interview got postponed by another week. The experience was good, like everyone else describes. Great office, lovely reception. First interview was with only one interviewer. It went pretty well. Didn't really expect me to code in any specific language. After first interview, was told to wait for 15-20 minutes. Second interview was with 2 interviewers. They were less friendlier but still polite and helpful. Could have done better but came up with solution for both problems. Was told to wait another 15-20 mins and was provided a sandwich for lunch. The weird part was having to sit in a conference room for the entire duration of the interview process. After the wait, was escorted out by another HR. That was when I realized that I would be rejected.

Even though I was happy with my performance, I probably could have done better. The interview process was good overall.

Interview Questions

  • 1) Given two integer arrays A and B, where A is larger in size than B, find the intersection of the two arrays, i.e. the elements that are present in both A and B.
    2) Given an unordered list of tasks, where a task is a class that has an id and a parent id, implement a function called killBranch. killBranch would be passed the task id that is to be killed and the unordered list. The function should kill all the children tasks of the parent task needed to be killed and return the updated list. (No brute force solution, or topological sort)
    3) Given a set, return the power set.
    4) Design question.

    Application

    I applied online. The process took 1 day. I interviewed at Bloomberg L.P. (New York, NY) in March 2017.

    Interview

    Applied online sometime in Nov 2016. Received a mail from them in March 2017 that they want to schedule a phone interview. The phone interview was exactly as expected with the same questions:
    The only unexpected part was that the interviewer was NOT friendly, neither was he encouraging. The interviewer was one of those who seemed disinterested and instead of understanding my logic, kept asking "Why does this test case fails". I made a silly mistake but I could have nailed it had the interviewer been at least little encouraging. Within 2 minutes of the end of the interview, I could run all the test cases - the error was so minor! I accept minor mistakes do cost jobs and take full responsibility, however,the interviewer was pretty disinterested which added to my problems. I provided a O(n) solution whereas the interview told me he does not think there is a solution better than O(n^2) which was , again, discouraging. Because, there definitely was a O(n) solution.
    Overall - my experience was bad.

    Interview Questions

    • 1. Tell me about yourself
      2. Why Bloomberg
      3. Tell me about your internship experience
      4. Coding question: given a array and a number k, find a contiguous longest subarray having sum <=k.

    Application

    I applied online. The process took 5 weeks. I interviewed at Bloomberg L.P. (New York, NY) in March 2017.

    Interview

    This is for the 2017 Software Engineer position. 45 minutes technical phone interview and then an in-person interview. Interviewer failed to call me twice which caused the process to take longer. Recruiter did everything via email which was bad. I wish I had an initial call to understand what the job entails and how the program is setup and ask question before the technical phone screen. Wouldn't interview with this company again because the entire interview process was messy and I was disappointed because I like the company. I found out that the first 3 months of the job is all training(getting to know the company, learning some languages and technologies), then there's a presentation from different teams, you later have to select one which you'd like to join after training.

    Interview Questions

    • Why Bloomberg? Tell me about yourself and what you do? Given 11000111, output how far each 0 is from the current index. So output should be 21000123   5 Answers

    I applied online. I interviewed at Bloomberg L.P. in March 2017.

    Interview

    I got an email from the recruiter a couple of weeks ago. The recruiter was friendly and she scheduled a call with a senior software engineer after a week.

    The interviewer called me on time and he asked me following questions.

    1) Why Bloomberg
    2) Explain a project that you are proud of

    Next, we proceeded towards the technical interview questions (Please see below). The interviewer was not nice nor rude. He has a different accent. I felt that he didn't pay much attention towards the interview. I have solved all the problems, I dont know why he did not select me. Anyways, overall it was a good interview.
