rant about ineptitude and honesty but I also want the job
A few years ago I interviewed for a job (at least twice) for which I was absolutely the perfect candidate in every way, plus several lengthy phone conversations. And it was mostly commission pay for which there is very little risk to the employer.
They strung me along for over 2 months and finally had me take an online "psychological assessment" after which they told me that I would not be "a good fit" ....
A couple of years later I was working at another place and we hired an employee from the company that I had applied to. After a few weeks of casual conversations, I suddenly recognized why I didn't get the job. He told me that one of the owners was a good friend of someone that I had worked with a decade earlier (actually for many years ending a decade earlier). Long story short this bastard had left our (small-ish) company in a very damaging and cruel way (including wiping the primary construction computer (rarely backed up, as in most companies) and deleting executive email accounts) to start his own business in direct competition with us. He knew that I hated him and there is no doubt that it was he who torpedoed my application.
TL;DR - hiring is a difficult decision-making process, and most managers do it with great trepidation
