It's easy to hire anywhere. But is it easy to get hired? How much rigmarole does a company put you through to ensure they're not going to get stuck with dead weight? I'm guessing quite a bit, and the harder it is to fire you the harder they'll work to make sure you're worth hiring.
For me it was a 1 hour chat over coffee. For the staff I hired it was similar.
From the moment the decision was made (an hour or so after the coffee), it is usually
a month until they are working with me.
We do reference checks after picking a candidate.
The month delay is due to the notice period people are usually required to give their old employer. It could be more or less but is 4 weeks usually.
The process probably varies by industry a lot. If a profession requires a practicing certification you have a minimum standard already. If a profession is tiny, you have a fair idea about candidates before you interview.
