Failing any interview is a real kick in the balls, particularly if you happen to be out of work at the time. But somewhere down the road you're going to laugh at the fact that you failed telling them about yourself. Like they would know.

I used to think that, but then I got laid off. That was a real hit to the ego, let me tell you.
The fact is that the right job is a matching problem across so many dimensions that change over time (sometimes quickly, sometimes slowly) between many parties (employers are not monolithic!).
Pretty much, interviewer clicked more with other candidates I guess. That does sound extremely frustrating to go through the whole ordeal just to have some guy weed you out because you don't look or speak like he expects.
