There's almost no firm with a bar to entry as high as Rentec when it comes to hiring, and almost certainly none with the amount of people who have cleared such a bar. Some smaller firms still hire similar quality, but RenTec has been around for so long and always has attracted the best candidates. It's not as simple as saying "they hire smart candidates" it's that they've hired the outright best in the market when possible.
