I haven't used Hackerrank specifically, but some other similar tools, and yeah, those were my exact feelings. Self-taught, been doing software professionally for more than 25 years, and have rarely ever needed anything close to the types of math/compsci problems these services test you on. The 'sit with someone for an hour' are far more indicative of how you'd work with someone because... you're working with them. 2 years ago I did a "remote pair code test" with the team lead for about 30 minutes. I think I got most of the 'test' done in half the expected time, and we talked about where/why I cut corners, how you'd test it, what sorts of things you need to keep in mind to address edge cases, etc. I got to see what working with the team lead was like in that case, and... ultimately, it wasn't much different after I got the gig. Good luck to you in your hunting!
