As someone who is actually hiring (not on the HN thread), has actually hired people in the last few weeks, is actively interviewing new people, and has had the "you're not actually hiring" accusation leveled at them,
please consider that maybe they
are really hiring, but:
- are swamped with people applying in addition to trying to build a product,
- may actually have hired someone, and that person may actually be a better hire.
I'm sorry you had a bad experience. I really am. That doesn't mean there's malice at play. Also, please try not to kill the messenger; it is entirely possible that even if malice is at play, the person you're talking to isn't the perpetrator. It would not be the first time that a hiring manager believes there's an open rec until they try to fill it.
I don't know what you are referring to with "SV pedigree nonsense", but I'm assuming you mean that people aren't willing to hire you because you haven't been in the right SV scene. That's certainly possible. I can also tell you that my team currently has zero people in SV, people across the US and outside of it (as in transatlantic), and we still had the issue I described above. That doesn't mean that isn't what happened in your case, of course.
