I interviewed at Cognex 15 years ago. They eliminated their EE department down to one H-1B who broke down in tears as I tried to figure out why I was being interviewed by people with no knowledge about the job. They were solely interested in the ability to reverse engineer something without any documentation. It was clear they were just repackaging cheap SZ camera modules in overpriced yellow boxes. Everyone was glowing about their "legacy" product line from before they canned their engineers. Nothing but crickets when asked about the new stuff. The founders had constructed this weird personality cult around themselves. Glad I dodged that bullet.
