Easy Interview

Application

I applied through a recruiter. The process took a week. I interviewed at Bloomberg L.P..

Interview

Contacted by a recruiter, then set up a phone interview, during the entire process I simply wanted to know that if they wanted to test me that they wouldn't be doing so on simple programming concepts that are just a waste of time considering the usual demands of such positions. Seriously if I've been working at large names as a programmer for over 6 years, I don't want to tell you how to program quicksort in c++ for the thousandth time, cut the useless filler and stop wasting peoples time and effort.

Interview Questions

  • All the normal stupid basic questions to make sure you have programmed at some point in your life, i.e. if you know how to do array/linked list, or any other basic structure you should be fine. Waste of time for me but might be worth it for someone else.   1 Answer

    Application

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

    Interview

    Had a 45-mins phone technical interview. There are 5 minutes of intro and 5 minutes Q&A at the end of the interview. Overall interview experience was okay, but it would be better if it was a video chat call instead because sometimes it's difficult to catch the interviewer's emotional signals over the phone.

    Interview Questions

    • Write a Stack class: push(),pop() methods without using built-in pop() method. Following questions was to write a MinStack class which contains a method that finds the minimal value of a stack using only push() and pop().   1 Answer

    Application

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

    Interview

    Applied online. HR quickly scheduled a phone screen.

    The interviewer asked me to solve a few standard interview problems. I solved the first one without any problems (even after he started imposing some random constraints to make it harder). He then described a second problem, even simpler than the first (remove odd elements from an array. I answered this in probably 10 seconds without any difficulty, but then he asked me to solve the problem in some other arbitrary way (which was neither faster nor more memory efficient). After making the problem as convoluted as possible, he clearly stopped paying attention to the interview. In fact, he asked me after 10 minutes "sorry, wasn't listening, what's your approach?" and then chided me for solving the problem exactly as he had asked!

    Overall I found the interviewer's behavior to be extremely disrespectful, and the entire process to be a waste of my time. I would have rather have been given a unit-tested HackerRank exam than an interviewer with a poor grasp of English and the attention span of a goldfish.

    Interview Questions

    • Solve the two-sum problem. Now solve it while minimizing amortized runtime. Now solve it again while minimizing amortized memory usage.   Answer Question
    • Remove odd numbers from a given array. Now remove them in place. Now solve it again, except solve it by partitioning even and odd elements to either side, then slicing the array (why???). After solving it exactly as described, the interviewer will chide you for not reading his mind and doing something else.   2 Answers

    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.
