Candidatei-me por indicação de um funcionário. O processo levou 2 meses. Fui entrevistado pela Bloomberg em jul. de 2020
Entrevista
Got to three rounds, all phone in. First round HR, next 2 rounds were technical. The interviews were generally around my research experience, followed by some design/mathematical questions. You should expect leetcode medium level coding questions during each round.
Fiz uma entrevista na empresa Bloomberg (New York, NY).
Entrevista
(1) Recruiter phone screen
(2) Hiring manager 1 hr interview, with another group member shadowing
(3) 1 hr presentation of past work
(4) 4 hr virtual on-site with the team

Candidatei-me online. Fiz uma entrevista na empresa Bloomberg (Londres, Inglaterra).
Entrevista
I interviewed for Bloomberg AI, London, UK. Interviewed till the final rounds. The whole process was two rounds of 1-hour video interview (one round per day) + Full day interview with 4 rounds.
It's very gender imbalanced. All interviewers that I met (about 10 people from AI team) were all male.

Pergunta 1
Video interviews were LC coding + machine learning questions + previous research/projects technical questions (for example, you used X in a project. explain algorithms of X. what loss function did you use?)
Full day interviews were similar to the video interviews. But one of the rounds was very software engineering focused.
LC questions were medium level, parenthesis, data streaming, k-largest.

Entrevista
There were 3 rounds in total. Two phone screens and then one virtual onsite. The phone screens consisted of conceptual ML theory questions and a Leetcode type question. For onsite, there were 3 technical rounds (one focussing on leetcode + ML theory, one focussing on only leetcode, and one focussing on ML design + leetcode) + HR round + Manager interview.
