> Even one company where I seemed to be an almost 100% fit didn't get back to me.
What's wrong with these hiring managers? I mean, I thought software engineers were super-much in demand. Every founder interview I read includes a complaint about how hard it is to find good coders. These companies publish vacancies, and then don't even respond to well-fitting applicants (I'm just going to assume that the author is compentent). Is this typical? Among "startups between 20 and 100 employees"?
