One thing to ask before is how often are you going to work. We have several drivers who only work a couple days a week. Or even once. They are working local sort and sometimes preload to get some hours.
Here, if you are hired before Oct. 1, you can still finish your 30 days during peak. That's not the same everywhere.
I was hired off the street almost two years ago. No regrets so far. I had health insurance after finishing my 30 day packet. I think I'm the number two unassigned/cover driver. Have like 14 drivers under me. The pay is adequate for now though waiting four years for top scale sucks.
If you can financially handle not working every day my vote is to go for it. Just don't burn any bridges. You have to get the job, like it, and qualify.
