Are there any jobs?
Yes. However...
A couple of UK/Irish jet operators have fallen in love with the idea of (self sponsored) cadets at the expense of experienced turbo prop pilots. Will this change? I don't know. So, unless you're on a structured/link full time course, the chances of getting a jet job soon after finishing training appears to be slim.
Although, if you do the reading, even the guys who have done the full time stuff are struggling to get a job.
Every thing changes. If you're lucky enough to finish when there's a hiring boom happening, you could walk into a decent job. When will this happen? Who knows?
So, caveat emptor applies here. If you accept that you may need to move cities/countries/hemispheres for your career then by all means, start. You may need to chase down the first job in a distant place. You may need to settle with the turboprop world.
Will that give you the return on your investment? Only you can answer that.
Like the lottery, you do have to be in it to win it. However, the lottery doesn't demand such an investment. Like the lottery, you may never win....
Good luck.
