Hi, if you do atpl theory and you have completed it, can you join the intergrated course halfway to do your flying training?
No, of course you can't. If you have already completed the modular ATPL theory then the rest of the training is, by definition, modular as well.
how do you get Cpl,
By completing the relevant theoretical knowledge exams (at either CPL or ATPL level) and completing the modular CPL course and passing the relevant skill test.
Do you need a type rating course to also get a job as a pilot?
Depending on what you want to fly, you will need either a type rating or a class rating.
if you get a sposorship from an airline and you enter the integreted course and fail the atpl theory do you still have to pay for all the course or just for the bits you have done then get kicked out?
If you really need an answer to this question then you have probably picked the wrong career.
