    Software Developer Interview

    Anonymous Employee in New York, NY

    Positive Experience
    Difficult Interview

    Application

    I applied through college or university. The process took 5+ weeks. I interviewed at Bloomberg L.P. (New York, NY) in June 2015.

    Interview

    Extremely smooth interview process.

    Start off with the application on their website. It was smooth and only a resume submission. After that I was emailed by Bloomberg to set up a phone interview which I did. The recruiter also shared a Hackerrank link for the interview. (if you are unfamiliar with Hackerrank I definitely recommend practicing on their website)

    Phone Screen (2 hrs):
    The interviewer called perfectly on time and was extremely nice. After testing the connection of the hackerrank session he asked about my experience which I had prepared and I described the tasks that I had worked on in my internships. Then he asked "Why Bloomberg". Definitely prepare a series of points for that as this is crucial to your interview. After that it was technical. Questions:
    - Given a set of arbitrary float numbers in an SQL table select only the ones that are exactly 4 decimal places
    - Remove arbitrary spaces from a sentence:
    eg: "The sky is blue " --> "The sky is blue"
    - Reverse an integer:
    eg: 3421 --> 1243

    I was then contacted within two days to schedule an interview onsite. The HR department is extremely efficient. They scheduled and paid for flights and hotel and they compensate you with a gift card as well.

    Onsite Interview (4 rounds):
    The onsite interview begins with the tour of the building. Its an amazing office. The tour ends in a room with the first set of interviewers who find you in the group of people and take you to your interview room where you will be for the rest of the day.

    Round 1 (2 hrs):
    2-on-1 interview. Interviewers are very very helpful. I feel like a struggled at times but they were encouraging and basically test you to your limit.
    First I was asked in great detail about my internship. Definitely prepare your background from your resume. They are extremely knowledgable and will delve into great details about past projects.
    The technical question was to design a stack with O(1) lookup for minimum element in the stack. They first make you optimize your design till they are satisfied and then you have to write code for push, pop.

    Round 2 (2 hrs):
    Again 2-on-1 interview. These interviewers were probably the ones who were supposed to be harsh. "Why Bloomberg". Be prepared! Then they asked about database management systems. Why is is better to have that over just creating text files? But he was never satisfied with my answer but I kept trying to resolve his questions without giving up. I think that is crucial. Then I was asked to design an address book which you can use to:
    a) Get the the info of a person from the name
    b) Get the info of a person from a number

    Numbers are unique but names are not. They will ask you to heavily optimize your design (most optimal design: use hash tables with key as the the name or number and value as a pointer to the location of info with binary trees to handle collisions)

    At this point I noticed people being escorted out. So basically if you don't pass your first two rounds then they walk you out of the building. If not then you have an HR and managerial interview.

    Round 3 (45 mins):
    An HR lady will interview you. At this point you've basically passed and they're just checking a personality fit for the job. This interview was mostly just HR related. Finding out status of visa etc. Expected salary? Where else have you applied? Do you have an offer? etc etc. Keep the answers to those to a minimum. Do not mention more than 1 or 2 companies.

    Round 4 (1 hr):
    Managerial interview was by far the most relaxed interview of all. It was basically just a conversation while delving into details about the past projects. I was also asked why I chose my internship and where I applied AND where I got accepted (that was definitely a little unexpected). We discussed my goals at Bloomberg and also extra curricular activities that I would like to get involved in. When were out of time she thanked me and walked with me till the entrance of the building.

    I was contacted within 3 days of the onsite interview with an offer over the phone. The official offer letter was sent by email a few days later.

    P.S. The interview process took around 40 days for me because I could not make it for the recommended onsite interview date for personal reasons and had to schedule for a later date.

    Database Administrator/Engineer Interview

    Anonymous Interview Candidate in New York, NY
    No Offer
    Negative Experience
    Average Interview

    Application

    I applied online. I interviewed at Bloomberg L.P. (New York, NY).

    Interview

    After resume submission, an immediate email from HR to setup a phone interview. Phone interview scheduled and HR claimed that this interview would be interactive with coding tests (so computer and Internet needed). The phone call was with a lone "young" manager/team lead (with probably others listening silently) who seemed in combination of being nervous/proud from the start. I felt more relaxed than him with database terminology. He wrote basic questions and most likely Googled exact answers for just a Q&A test - there was no live SQL testing at all (as HR claimed). I'm well verse in the SQL language and it was clear that the manager has weak skill in programming. He claimed 10 years experience at Bloomberg as an Oracle DBA, MS SQL DBA, etc but again, he needed to write down a list of basic questions and exact answers for himself. 10 years experience of repetitive DBA tasks (including replication methods, HA environments, 5-6petabyte database environment, 35,000 unique databases in clusters) within the various big RDBMSs in a prestigious company and he needs a piece of paper with basic database questions/answers in front of him - Amazing, just ridiculously amazing. As a mostly self-taught RDBMS professional with high credentials in other fields, it was easy to see that he is quite weak.

    In reality, he is just a database analyst who was invited to become a database manager due to politics (he told me at his proudest moment). His interviewing skills were definitely amateur at best (too friendly, too nitpicking). To be fair, I didn't prepare for Linux programming questions so those questions I couldn't answer swiftly. SQL answers were easy and spot on.

    Senior Software Engineer Interview

    Anonymous Interview Candidate in New York, NY
    No Offer
    Negative Experience
    Easy Interview

    Application

    I applied online. I interviewed at Bloomberg L.P. (New York, NY) in July 2017.

    Interview

    -2 Phone Screens, including coding and problem solving
    -F2F interview ( 2 rounds, 2 interviewer each)

    Sailed through 2 phone screens which were harder than in-person, was let go after 2nd round in-person. No courtesy of feedback, received automated response saying I am not being considered for position. The reason I am writing is I thought I excelled in in-person interview answering all questions to the fullest demonstrating my thinking process as well considering all edge cases and reached to the answers. May be I was not match for position or vice-versa but they needs to at least have courtesy of constructive feedback assuming time and effort we put in.
    Note for future candidate: If position is requires C++ and if you are Java person, DON"T APPLY!!! They do not understand JAVA API, as answering questions in Java backfires!
