It already is a black mark since years if it was your only relevant employment.

Not because they are bad employees, but because they to used/focused/conditioned on Big Tech work. Which has often very different requirements and processes. Or in other words for such employees it can be especially challenging to onboard them. Which historically seem often is combined with an increased risk of them leaving your company not to long after on-boarding, weather that is for a different startup which now takes them or for founding their own company because they have the money reserves to risk it.

Or in other words, it's in general a risk you don't want to take when hiring.

Exceptions include: You have problems to hire anyone qualified. The person can somehow show through other qualifications that this isn't really a risk (pre "big tech" work, sometimes open source contributions but not always, etc).
