Wow, that's very bad, I don't think I've had one that bad. Outright insulting you in the interview is simply uncalled for. Cutting the interview short is fine for both sides, hey it's not a match, any questions? Then goodbye.

In tech we have some thing like that called the "Bar Raiser" interview. Typically it's the second to last interview, last one being with people/culture/HR. The bar raiser is to "See if the candidate raises the bar". It's a horseshit way to justify "Belittle them and make them question themselves so much to see if they crumple under pressure". Amazon did it to me, after 3 hours of straight interviews the 4th hour was the bar raiser. At that point I hadn't eaten since breakfast, I had shakey hands, and was asked to implement binary search from memory on a white board. The "manager" then berated my implementation for 30 minutes and questioned every detail. I was very close to just passing out because I was so hungry. I remember literally stumbling nextdoor to mcdonalds and eating 3 cheeseburgers in under 5 minutes. No one offered me coffee, water, or a snack.

I bring this up now because maybe they were trying to do that, but they did it very poorly. The one credit I give that shite manager was that he didn't belittle me, only everything I did. He never raised his voice either, only interrupted me constantly and rudely brushed off my answers. Granted, I hear that's standard at Amazon.

In both of our cases, they do a great job at showing their place is toxic as fuck, and it was good we moved on. (Fun thing, I was laid off a few years ago and had the opportunity to reapply at Amazon, but luckily got another offer last minute. I ended up turning down Amazon, and man they do not like when people do that. You can tell they have just reports on reports to figure out why someone wouldn't want to work there!)
