It's fine if you believe this is true for your environment, but that's really quite rare. I can see 'high pressure' particularly in Devops, but that's a different kind of problem solving. The headline speaks perfectly to my intuition after many years in the trade, and that we are 'measuring confidence'. Note that they assumed that interviews were set up to be fair - they are not - and that's actually ok. If a company has preferred candidates, it's perfectly within their right to do that (so long as 'preferred' doesn't just mean 'gender' or whatever). It's been a while since doing this for me, but when I do it again, the 'on site' will be a page with some neat problems, some Q&A and then they take basically as long as they want to go through them, the interviews start when they are ready and you just go over 'what they did' and then interview for the rest of the issues. 'Having someone watch you solve a problem' is very specific social condition.
