1. Looking for a non-full-time job I got told "but what if we need you on Wednesdays?", i.e. the day I was going to be taking care of my kid instead of working. Eventually found another part time job elsewhere (https://codewithoutrules.com/saneworkweek/ if you want some tips on how you can do that sort of thing).

Was reassuring insofar as it wasn't "you're not good enough".

2. Interviewed at startup, it goes well, then silence for weeks. I ping them, and eventually they said they're having some internal problems and if I have another offer I should probably take it. They apparently had "internal problems" for years, as in one review from 6 years later where it was still "it's a startup, don't know if I'll have job next week".

The job I did end up taking worked out very well.
