Block Software Engineer interview questions

Phone call with a recruiter - they give you the choice between a take home project that takes 2-4 hours of work or a phone screen. Then Typical on-site. I took the phone screen option because who the heck has 4 hours to do free work :( The interviewer was nice and I write the solution and ran it successfully. Everything seemed to be good. But I never got a response from Square after that phone screen. Not even a "We've decided to go with someone else". Very unprofessional.

Technical phone screen with an engineer was as far as I got. It's intended to be a "pair programming" session, but I'll just say it didn't feel very collaborative. The first layer of it was an LC easy/medium style problem. Once I got a working solution for that, he added a 2nd layer of complexity. I described my approach, but he seemed resistant to it, but did not clearly articulate what the problem was. I couldn't tell if he actually saw a flaw or was testing my ability to defend my decisions. Either way, his pushback threw me off, and maybe that was enough for a rejection. I tried to explore his reasons more to see if I should consider a different approach (trying to be collaborative) but maybe this came off as indecisive. I did not get any feedback on what I should do differently, and I couldn't think of anything on my own, so decided to go with my idea. Ran out of time implementing it.
