Ask HN: Onsite coding interview laptop and dev tools

A good workman never blames his tools. Today, I had my first and worst onsite coding "pair programming" interview experience. Note that I've done timed take-home exercises with no problems and really enjoyed them. It was a 45 minute task with a shitty dim lit 13" IT notebook on power saving mode. It took me about 15 minutes just to get the hang of the unfamiliar keyboard layout so all your shortcuts from Copy and Paste to comment/uncomment keep glitching and the pressure of making sure every keystroke is perfect with the interviewer you're paired with. It was quite dreadful, missing keystrokes, things falling apart, just zero "flow" and mounting pressure.

How common is this setup in interviewing? Am I being unreasonable in feeling it was a total waste of time?

We made some headway but it was clear I was not moving fast enough.
