i was hiring for a senior devops role a few years ago. part of the interview was ssh into a machine and debug some web server configs we purposely broke. step one was email an ssh public key to me. now, i dont remember the command cause i do it so rarely, i dont expect them to, but for a senior role we expect you can google this, its not supposed to be hard. the number of people that could not generate an ssh key was crazy. i had people emailing me their current company private key. and if we did spend half the interview on the key, they never could pass the trivial part of how we broke it, which effictively just required reading the log file.
