When I was not employed, I paid for the gas to drive 90 minutes each way and spent an entire day not looking at other opportunities to be hired or other ways to improve my resume, only to be told by the director that although I did very well in the interviews, they would be getting back to me in 3 months when they found out if their hiring freeze was over then, because at the present time the opening was not yet truly open.
Have some respect for human beings, regardless of their employment status.
I don't study for their stupid whiteboards and I don't study their stupid leadership principals. I on purpose refuse to use them during behavioral interviews (also refuse use the STAR method). I've had at least 5 full onsites like this. By my calculations, the wasted time and effort from amazon on myself was worth at least 100K given the number of highly paid engineers/managers who wasted their time interviewing me.
But those emotions are dwarfed by Amazon-directed Schadenfreude. Well done, sir/madame.
This is basically public service work.
