funny thing was he had other places on his linkedin under "active employment" but we never really dug into it (until we learned he was full-time there) because he just seemed like the kind of person who wouldn't keep his LinkedIn up to date.
He was a solid middle of the pack contributor on net, but it was clear he was way stronger than his net output just from interactions with him (he had great products ideas, clear technical understanding of many areas, etc).
he's a really talented engineer, crushed our interviews. the funny thing was that he actually had multiple companies on his linkedin at the same time, including ours. we just thought they must have been internships or something and he never updated them (he felt a bit chaotic). but then it turned out he was working at all of them simultaneously.
worked for us for almost a year and did a solid job (we also let him go when we discovered the multiple jobs)
