I applied through an employee referral. I interviewed at Bloomberg in Sep 2019
Interview
Referred by a friend. Took about 1.5 months from application to offer and a total of about 8 rounds.
Had an initial call with the recruiter regarding the role, fit etc. This was followed by 2 phone interviews which were both coding + discussion, 1 hour each.
Then had an onsite in a few weeks. The first round was high level design + role specific questions. The second round was coding + low level design. Next 2 rounds were straightforward, one with an engineering manager and another with the HR. After the onsites, they scheduled 2 additional interviews with senior members of the team, both of them focused on past experiences, high level engineering and overall role + culture fit.
Got an offer within 3 days. Overall, I loved the interview process because what I realised was communication and collaboration skills mattered far more than mindlessly pumping out code. The interviews are geared towards checking these skills which I really appreciate.
Interviewers and HR were friendly. Overall, the process was extremely professional with minor to no hiccups.
I applied online. The process took 3 weeks. I interviewed at Bloomberg (New York, NY) in Jul 2020
Interview
45 Phone Technical Interview session was setup on Hacker Rank followed by HR phone screening. First 10-15 min introduction talking with interviewer and then, followed by 30 min coding session to solve the problem in Hacker Rank. Please watch time on introduction session, it is better to use more time for problem solving. Problem solving time was too short.
Interview questions [1]
Question 1
Solve the problem in HackerRank code live.
10-15 min introduction with interviewer and 30 min to solve the problem. Problem was CandyCrush problem, to write program such that for given string, if three or more repeating adjacent alphabets can be removed.
Initially, I was solving this without recursion approach, it got mess up after removing the substring of repeating string, then, when returned, it may be have again the repeating strings like "abbbaac" => "aaac" = "c".
I applied online. The process took 2 months. I interviewed at Bloomberg (London, England) in Aug 2020
Interview
After applying online, I had an initial call with a recruiter and arranged (via an online booking system) a 60 minute telephone / hackerrank tech screening.
The tech screen was with a member of the team that I applied to. I was asked one larger problem that was mostly a test of basic design & data structures. I received positive feedback within a week and arranged the virtual on-site.
In the next round were two more 60 minute coding interviews with a similar format but more members from the related teams (2 per interview), and of course via video conference. There were a total of three questions of different styles with different follow up questions. I did not find any of them specifically on leetcode but they were generally a chance to demonstrate the usual algorithm & data structures knowledge like arrays, graphs, time & space complexity etc plus some basic functional concepts.
The interviewers were welcoming and helpful - in the first interview, the interviewer could see I was taking a more complicated path, and I was given some guidance toward a better option, which I followed.
At this point there is a decision on whether to proceed to the afternoon. The result was positive so I then had:
- An interview with the hiring manager
- An HR interview
- An interview with the manager of the hiring manager
After the relative stress of the morning these were actually quite relaxed interviews / conversations without any focus on behavioural questions, more about interests and projects, and how they relate to the role - but this would probably vary depending on the team and role. I also learned a lot about the team and how everything works.
Finally within a couple of days I had a shorter call with a more senior manager in New York, which again was not so much an interview as a conversation.
Overall I was very impressed with the team, the culture and the obvious passion for technology, and I was actually quite sad to eventually have to decline the offer.
(Note that the process was long, but largely this was because of my pacing out the interviews a bit, I think they are often much faster)
