>What kind of companies are these that their engineers need to write perfect code under severe (i.e. on the order of minutes) time constraints?
I, oddly, had to do that once in my career although I had an hour or so. Retail advertising, Cyber Monday, data pipeline is backing up severely, advertising budgets aren't updating, only other data person I can reach is drunk. Bottlenecking code is written in perl. I don't know perl. And no real testing environment. Very stressful hour of my life.
edit: Of course, such things happening often enough to note are generally a symptom of bad process and management, probably a lot of technical debt as well. So generally a workplace to avoid.
