I sent an application for a role at a startup. After a week or so I got an email from a recruiter and we scheduled a first interview. The recruiter was very enthusiastic, giving lots of good feedback about many of my answers and saying how it looks like I would be a great fit.
We scheduled 3 technical interviews in a week. They were all quite positive. The recruiter was in touch often giving me feedback and explaining the next steps. We made 6 calls in total, and I spent hours talking to people at the company during a couple of weeks. It all seemed quite positive and they were also open about my not so strong points and my willingness to consider different roles (for the same salary). After the interviews several people said I would be a great fit for the company.
My 7th or 8th conversation was with a VP. That was a friendly conversation but at the end the VP didn't seem convinced I was a good fit for the initial role. After a few days I got a call from the recruiter saying they wouldn't be progressing with me for that role but we would move ahead for the others and they would be in touch. A few days later I got a message saying they had a meeting to discuss this. The next week I got another saying they'd be in touch very soon, hopefully the same day or the day after. Then another nearly identical message the next week. I replied positively to all of them.
A week later I sent another message asking for an update on the situation and it was ignored even if it was read. Even if they contacted me again I would most likely reject an offer at this point, since I found their behaviour in the last few weeks very unprofessional and unkind, after so many hours spent together I think it's inappropriate to just ignore a person like that.
Now my question is: I kind of feel the need to send some feedback to the VP. Not about me not been selected, that's totally ok, but about repeated promises (unrequested by me!) to be in touch "today or tomorrow" and then just ignoring me. If this thing has happened with me I doubt I am the only one and the VP might not even be aware of it. It would also be a way to get this out of my chest. On the other way, I fear it could come across as condescending or vindictive and I don't like burning bridges even if I won't be working for this company.
