If you've worked in startups before and then go on to big companies, you will have learned those terms, so it just depends on where your fellow engineers are coming from.
Still doesn't match my experience. Even in the startups I've worked for, engineers did not concern themselves with those kinds of details. Maybe it's a factor of just how early in the lifecycle a startup is when engineers join. Perhaps somebody who is there "day 0", before the first round is even raised, or maybe just a seed round, has a different perspective than somebody who joins after a C round or what-have-you.
