Not just strict, but their interview process is high-leetcode/old-Google-style.

I wouldn't bother unless you're an ex-FAANG engineer with a hefty resume and regularly practice hard-level algorithmic problems.

Yeah, because we are a remote-first company, we only hire mid-level & senior engineers. I think it does a disservice to early career engineers to work remote. There is a lot you can learn by working in a much higher bandwidth communication setting.

speaking of remote-first, you accept applications only from US and Canada, not Europe, right?
