The company was Swedish, but was eventually acquired by an American corporation.
One of the projects we were working on started getting delayed due to endless discussions about which tech to use and how to architect things (the companies used completely different stacks) so we could integrate everything. One day, we had a video call with one big Manager from Florida. The guy just started shouting like a maniac and treated everyone, including us and his American team, like crap.
That was so incredibly surreal to everyone on our side, as even the tiniest raising of your voice in our office would've been extremely unusual, and Swedes are one of the most conflict-avoiding people you can find anywhere. After the call was over, everyone was all thinking like "what the fuck just happened" but no one said much at all... we just kind of pretended that did not happen and slowly went back to playing some ping pong and calmly sitting at our desks and doing some work with headphones on.
After a few months, only I was left on the team as everyone just found elsewhere to work.... I followed a couple of months after.
