Fortunately not every company is like that. I’d suggest finding the good ones.
I think you've found the core idea.
Some profession include situations with actual stress and mortal danger. Doing good programming should be more like solving high school math problems in solitude than a high pressure social interaction.
Or: if your development environment has high stress interaction get a consultant to settle the issue, you likely have multiple issues that need to be dealt with.
Performance anxiety is real though. One mark of a good interviewer is how well they can get a candidate to relax and perform at their best. I’ve done over 400 interviews and I still worry I don’t quite have that skill down.
You don't understand the problem, and are doubling down on the solution. Sadly common.
Like how? Honestly. What answer are you immediately looking for if there's a bug? You're looking for a fix, not an answer. And it takes time, a bug fix for a non trivial production system is almost always 10+ minutes unless it's some silly html/css bug.
