Nah, lots of places try to make interviews as unbearable as possible. It’s “how they judge your ability to work under pressure”. Like my previous employer would fly you in seemingly with as many layovers as possible so you’re exhausted by that night. Put you up in a crappy hotel and make you come in super early. Put you in a tiny room and make you stay there for about 9-10 hours of intensive back-to-back interviews with a 30 min box lunch break. Pretty similar tactics as the military. And it’s not uncommon in tech.
