This is probably just a "public resume". He obfruscates company names ("social network company in 2008" huh...) and admits his timelines for technologies is a bit fuzzy. Probably a mix of ageism shielding and privacy despite being a very publicly spoken person.

That or he truly did work at a "nepo company", as he phrases it. Not many people can just travel the world for 5 years, let alone boast about it on their resume.
