1. Screening Interview, the usual stuff, what's your background, where are you coming from and stuff like that. 2. They send you a take-home assignment, they wanted to test how well you did on Concurrency and Parallelism, they expected me to get it done in between 3-5 days. I did the assignment in 2 days, but I got rejected, because the code reviewer nitpicked something that in the instructions was badly phrased. i.e They "recommended" not to use Promise.all or similar, I used Promise.allSettled because it was confortable to use, got rejected cuz of it. So, please, make clearer instructions, and set clear restrictions on what do and not to do.
