Do we know what role Acton applied for? I saw the twitter posts about the rejection but never saw what job he was applying for. It's hard for me to generalize about the industry from this one specific case, without even knowing what job he was allegedly rejected from (his experience may have been undesirable for an entry level position where the hiring manager felt he was overqualified, or conversely he probably lacked the experience at the time to get the role of CTO).
