They were not, but they were super, super nice about it. I was on all their email lists and they would reach out from time to time. In fact the founder took me out to lunch at least three years later just to catch up and see where I was.
He didn't have to do any of this. I've never had anyone but consultancy recruiters keep in touch for that long, and they often feel fake and exploitative.
There was an old saying in Seattle that 'Seattle is a small town'. From a software perspective, there are a ton of people in the city, but up until pretty recently you were virtually guaranteed to bump into old coworkers again, or at least work with people who also worked with them. It's no good pissing off people who aren't a fit for this job now but might be a great fit in three years. They may remember how you treated them... Google.
