With a traditional interview and job offer process, a new employee can ramp up without worrying their job is on the line. And I think this is important, because it can take awhile to ramp up to full productivity, which can be stressful if the new employee feels like they're being evaluated already.
Where I've worked, my new manager told me "Hey, welcome to the company. Please feel relaxed and take your time ramping up, you've already passed the interview and we're happy to have you here."
With your process, how do you deal with people getting stressed out during ramp up or feeling imposter syndrome?
