Well, this is a function of lining up so many. Apply for 50, get interviews at 30, you end up with maybe 1 in 3 have aligning timelines, pass 1 in 3 of those, and you have 3 offers to choose from at the same time before they explode.

Lol. Offers don't really explode on timelines less than a few weeks. If you get pressure from a company to accept their offer in less than a week or 2, that's a red flag, especially if they want you to start right now.

Ah, interesting. I admit that I am often a schmuck that takes contracts at face value. I have always had it be 24-72 hours. I have even been asked if I would accept an offer immediately (without knowing the salary range or whether I would get permanent remote).
