Blueface Senior Python Engineer interview questions

A recruitment agency approached me with this role. Soon after applying for this role, I got a take home test from company recruiter(which took me approximately 3-4 hrs. to complete). After submitting it on given time, I waited for more than 2 weeks for their reply. The reason I didn't get any reply was probably, they were talking to other people. I got rejection after almost 3 weeks and when I asked for their feedback, they had none. This was a bit frustrating, as I invested my time in the process for no reason and had to wait for them to find more suitable candidate.
