I applied through a recruiter. I interviewed at Bloomberg (New York, NY) in Jun 2020
Interview
Typical coding interview, easy medium questions for both phone and onsite. Not sure about further rounds as I only made to onsite. Behavioral questions are also asked during each round.
This interview is with people from Asset Investment Manager (AIM) group and they are some of the rudest interviewers I ever met.
Onsite
Round 1: describe about favorite project and then bunch of trivia related to languages listed on my resume. The interviewer at some point was specifically looking for my answers to exactly match the answers in his head and looked disappointed when I did not answer it that way; it's not a Q and A session - they should learn to be more mature when asking such trivia questions.
Then a medium LC question related to scheduling - solved it and ran test cases
Then next question related to strings - could not code up completely because of time constraints
Round 2:
Another rapid round trivia session and favorite project
LC medium question on graphs
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.
