By the time you realize someone is a fraud you've disrupted your progress for months compared to where you should have been, and firing people is not free in terms of culture and the psychological health of your other employees and their families. If you have to fire someone because they don't fit the profile you actually want you have severely fucked up. That's IF you can tell. Most people can't tell who is talented and who is not even after hiring them. For every highly skilled / talented person there are 500 that think they are and have a resume that is consistent with that, but they are still trash. If you are hiring/firing this much of the time your company culture will become a stalinist purge mentality where people have no trust or loyalty in each other and act primarily out of survival. That means they will withhold help from each other and even sabotage things to ensure they aren't the one the bear catches that month. Maybe you have only ever worked at terrible giant tech companies or come from a culture where this is normal, but it's literally death. The culture you really really want to have is a group of genius misfits on a mission from god, very hard to join but steadfastly loyal to each other, and willing to pour their entire life into achieving their mission. I think this is a theoretical exercise for you, you should revisit this after you have some experience.
