Lol. Never jump straight to a LCC flying Cessna 172's. You will have a bad, bad time. And potentially wash out. If you don't wash out, you're looking at a line check failure down the road, or recurrent failure. Go to a regional first with a proven great training department (endeavor, Mesa, republic). Finish IOE, get 500 hours, and THEN think about the big boy jet LCC's.
Failures weren't so common because in the past, you'd have 1000 regional jet hour guys, or RJ captains come on with great jet experience. When you hire a 1500 piston cfi, it's a whole other story. Sure some can succeed, but failure is still on the horizon and it's not a walk in the park.
