The tech questions are very generic about software development principles: recursion vs iteration, heap vs stack, DI, TDD, time & space complexity, concurrency and multithreading, ... The home test is an absolute waste of time. Can't give much info but it was simple, it was more about the quality of the tests, handling highly concurrent scenarios and whatnot, but the funny thing is that the feedback they provided was not even about what I submitted. Is like they reviewed someone else's code. Asked for a second review or at least to double check they didn't mix reviews and didn't hear back from them. Very disrespectful and unprofessional.
