This makes no sense to me. Most candidates aren't unemployed; they're switching jobs. Leaving a job they don't like, or looking for an upgrade. Many have to be persuaded to leave their current employer. If I were thinking about switching, I'd want a lot more commitment from my future employer than "we'll hire you and four more guys for the same position, then we'll see which one of you will last 90 days". Regardless of my confidence in being able to do the job, who wants to compete for a job for 90 days? Interviews are horrible and stressful, but this is just replacing them with what is essentially a 90 day interview for which you have you quit your current job.
