How would you even go by looking people to do this? Especially someone familiar with the tech field for example? "hiring manager technology" doesn't return the best results in trying to find someone.
Gonna have to talk to friends and coworkers. I've done this (mock interviews for people who are bad at interviewing) for friends and even friend-of-a-friends, but I wouldn't want to be on a searchable directory of such people.
Yeah that seems to be the common theme, "Ask friends and coworkers" I guess I need to do a bit more networking at meetups at such. Its been word of mouth from previous clients for all these years so I never bother to reach out to build a network.
