I was given an access to a virtual machine that had a simplified copy of Balyasny work environment with various things broken. I was asked to fix things and add some implementations. This is a good approach in theory, but there were a few things that made it terrible. - There were simply too many things to do for 45 minutes - The tasks were linear. E.g. you could not move on to programming until you fix the Docker container, since their software does not run without docker. The container was broken in a non-trivial way, e.g. the main project run was part of the build step. It is hard to figure that out unless you know what the project is supposed to do. - You could Google things, but they insisted you do inside the virtual machine, which made scrolling PAINFULLY slow. I don't think it was intentional, but it slowed down things quite a bit So, the problem with the interview was not that it was difficult per se, but that it was trying to test too many things at once over a very short period of time, without even theoretical possibility to finish them all.

Pretty standard , 3-5 interviews that range from technical ability to culture fit. Meeting with global team members and cross team leaders. Very smooth process and very responsive interviewers. Well organised company.
