You'll never know.
Speaking from personal experience, it's not that you didn't get it. It's that you'll never know whether you should have gotten it, because no one's going to review your specific case. I can take losing in a fair fight. But losing because it was rigged against you? It just diminishes all the fighting that it took to get yourself to the decision.
It just always sits as a nagging thought in the back of your head, in the pile of "shoulda, woulda, coulda"s, even if you end up just fine or better off without it.
Right. I can take being beaten out by someone more qualified or, hell, even someone who just had a better interview. But this is terrible.
I would have preferred they just came out and said "we're not going to hire you because you're a liberal." I feel like an idiot for playing along with their dog and pony show.
