Yes you do ;-)
If you think it's even possible to get a Learjet Captain position out of flight school, you might want to do some more research.
Also you said ATPL in one of your post. You have to understand that you don't get any ATPL out a flight school. To make it simple, the ATPL written exams is the theory you need in order to get your CPL licence. If you don't write those ATPL theory exams, you need to write the CPL and IR theory instead, which is almost the same. Nobody get out from a flight school with an ATPL licence. It's a CPL licence you'll get. An ATPL licence will come after a few years of real experience flying with your CPL licence.
