I also went through something similar over the past month looking for work. My main problem was that a lot of startups tried to lure me into their teams by offering a really senior technical management role, then once I had passed all the technical tests, the role ended up being 'senior engineer' (or similar) even though they said they were extremely happy with my test results and interviews. It's clear to me that they had never intended to offer the senior position and just used it as bait. Other times, they said I would be interviewing with the CEO but when I got there, they put me through some standard recruitment process and I didn't even see the CEO. This destroys the startup's credibility in my eyes. I cannot work for liars. Making me do all these tests before telling me what I was really applying for shows that they completely disregarded the value of my time.
