All the process was very smooth. Firstly I was asked to complete phone interview (about 30 minutes), quite easy algorithm interview. The second one - video interview with two engineers, as easy as the first one. Two questions related to data structures. After a week I was offered to go to London for the in-house interview. Bloomberg provided an invitation letter for a Visa Centre and paid for flights to London and a night in a hotel. Onsite they provided a quick tour of their great building and a breakfast with engineers. The first interview was a coding one, quite easy (binary search in matrix and data structures). The second one was about previous projects, experience, interests and software design. Was rejected after this one.

One hour technical interview conducted over Zoom for a python & c++ role. The interview focused on operating systems concepts and multithreading. Questions covered synchronization issues and required. The process was technical, clear, and well structured.
