> Give everyone a long probation period, and allowing them to seek feedback frequently as to how they can influence the decision to hire them on a more permanent basis so that the final decision will not be a surprise binary event.
Hypothetically, let's assume every company follows this method and around 30% of the employees who went through long probation period didn't make it through. Wouldn't that leave the employees in an even worse situation than getting rejected immediately, since they resigned their current job and now everyone in his professional circle knows that he or she didn't make it through company X's probation period? In addition to that, the employer will also accrue a lot more negative publicity from the employees who didn't make it through.
