I have only done whiteboard once, it was horrible, like peeing in front of a crowd. Did they try to find the worst way to asess talent and settle on this? Lol. What is wrong with pen and paper or typing on a large monitor everyone can see? I can hardly read my own handwriting.

I did see a lot of merit in practical+Quiz-format questions to filter out like 80% of applicants. The rest, just lock them in a room with the problem and see how long it takes them and the quality of their work. Infosec is broad so some roles you really just need to know the word cyber and say it a lot with powrpoints and other variations but on the other end you reverse new malware so you can develop day-1s but only for secret attacksim to test and develop defenses. I wouldn't use whiteboard or take home for either end but maybe for college grads and appsec type focused people that are still academically minded it takehome might make sense.
