Easy Interview

Application

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

Interview

A recruiter got in touch with me shortly after online application (around 2 weeks). First step scheduled for the following week, technical interview on HackerRankX. The interviewer was very nice and (seemed) happy with my solutions, as I was getting positive feedback along the way. I got cut off and they didn't provide any feedback. Disappointing.

    I applied through an employee referral. The process took 4 weeks. I interviewed at Bloomberg L.P. (New York, NY) in May 2017.

    Interview

    Applied through employee referral . Got an email back in a week asking to schedule a phone interview. Had a one hour phone interview, talked about resume, why Bloomberg, basic algo/datastructures. The next day got an invitation onsite. Onsite spent first 30 mins touring, then split up into individual interviewers. Two technical rounds about an hour each. Then waited 45 minutes for the next interviewer to show up. Senior Engineer, system design question. Then a 30 min HR interview afterwards. Got email back one and a half weeks later telling me I had been rejected.

    I applied through an employee referral. I interviewed at Bloomberg L.P. (New York, NY) in May 2017.

    Interview

    The nearest interview date was about 3-4 weeks from after I got the interview date. Recruiter was 15-20 minutes late. I was led into a room and interviewed by two more senior engineers for an hour long round of standard interview questions. I had lunch in this room, and some time later two different senior engineers came for the design round. One interviewer (Tom A.) did all the talking, and the other interviewer sat in silence and watched. Tom would ask 3 different questions and then ask you to respond, which I found annoying. Further, Tom asked very basic questions about every little technical detail and asked me to speak to him like he didn't have a technical background (What data structure would you use? What's a hashmap? What's a bucket? What's a hashcode?). This made solving the problem slower, but maybe it was a test for my ability to explain basic things effectively. Didn't get invited to further rounds, which as I understand means you didn't get the job.

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

    Interview

    Pretty smooth but kind of long interview process. Quick phone interview followed by an invitation to an onsite interview. The phone interview was pretty easy---I'm not a CS major and the interviewer knew this and asked questions tailored to my background. I had less luck at the onsite and the interviewers seemed to be expecting a solution that I hadn't encountered before. It's not their fault though, the question was still relatively easy with good interview prep and should be very doable with a solid CS background. Had two rounds at the onsite and was sent out, which meant I didn't get an offer as I expected. Still, it's a well-ran and not too difficult process
