Not only do they only want to hire those types, but I've been in plenty of rooms where the stereotypical young engineer outright refuses to acknowledge the older people in the room, as if they're beneath him/her. They have no respect for that person's opinion, and therefore show zero respect to that person.

We've all been in rooms where someone misses the point, or says something that proves they're not keeping up with the conversation -- it happens. What's unique about people in the bay is how unforgiving and judgmental they can be about those errors, and it's only heightened if the person is above a certain age.
