Ya, standard is 2 weeks starting off, then it increases over the years. You also usually have to actually accrue those two weeks over an entire year. Usually caps out at around 5 weeks or so.

For me it isn't the PTO. Say I want to interview at 10 companies to see which is the best fit. That's 10 days of interviewing. If they are all 3 day interviews, that's an entire month.

I get tired of talking to people about nothing after an hour. If someone wants to bring 5 people for me to talk to about smalltalk and nothing really of substance, I won't do very well.

20 years ago, a friend who worked for a guy who would hire 10 people then after a few weeks, fire most of the ones leaving just the best. I live in an "at will" state. I guess most people just don't have the stomach for that sort of thing, so they try to make up for it with 3 days of doing nothing really relevant to the job.
