No I don't think so. It sounds like he was fired for at the very least strange behavior, and all of his potential employers picked up on it. If he were technically good, it wouldn't matter what Chrysler said. But it seems like he's not technically good.
Maybe an awesome engineer in tech can get hired even if his past employers deny employing him. But what about a perfectly average engineer in something more traditional like automobiles? It's my understanding tech is pretty unique in being "less" sensitive about pedigree.
