First PR at my new job came back with 47 comments and I sat in the bathroom for ten minutes

Forty-seven. On a change that touched maybe 200 lines. Naming, an early return I'd missed, a pattern the team stopped using a year ago, tests I'd written in entirely the wrong file.

My honest first reaction was that they'd made a hiring mistake and this was the evidence.

What actually happened: I fixed all of them in an afternoon, and about forty of them are things I now do automatically. The reviewer told me later he leaves that many on everyone's first PR, because the alternative is you learning the same things one at a time over six months.

Still felt awful in the moment though. Did anyone else's first review look like this?
