Was contacted online by the recruiter. Had to do a type of interview where you video-record yourself.
Got invited for a meeting a week later. However, they canceled an interview a day prior to it and sent me a technical task (without previous arrangements with me whatsoever, never bothered to check if I had free time to do it. )
They gave me 2-3 days timeline to finish it (In the middle of the week).
I did solve the tasks, however, the second task had an obvious error (They were modifying it, but forgot to update comments or test cases)
I finished the given tasks in time and fixed their errors. Noting in my own comments that their own tests will not work because I had to edit it.
A day after they just replied with copy-pasted text saying they were not interested. I politely asked for more info, just in case I had missed something and made an error myself. But they never answer.
My only conclusion is that they just ran the tests and never bothered to read my comments. So I guess that is not a good sign.
