In my case, the personality problem might be the ever-increasing paranoia that I'm being rejected on the basis of some outlawed or unethical criterion, and subsequently ignored upon orders from the corporate legal or PR department.
It's one of several plausible hypotheses I have for the observed behavior. Very few are compatible with a healthy future employer-employee relationship.
This is one reason why I hate the brainteaser questions. I was told for one such question that I was the only candidate to give the correct answer. Then the interviewer suggested that I must have encountered it previously, even after seeing me "showing my work" on a whiteboard. Can't win; if you didn't lose, you must have cheated. That company blackholed me after I flew in from another city to spend a day-long interview with them. They didn't even reimburse me for my personal travel expenses.
It was Spatial, owned by Dassault, near Denver, in case anyone cares. That was, in fact, the second Denver-based company to do exactly the same thing to me. The first flew me in, interviewed almost all day, then cut off all contact, didn't pay travel expenses, and even tried to stick me with the cost of the hotel stay by canceling their payment. That was Tyler Tech, Eagle Division.
Neither are unique in cutting off all contact, but they certainly are remarkable in waiting until after an in-person interview by a non-local candidate to do so.
