Hey Sym, welcome.
I would think not. I don't think the courses themselves are the issue, but more the lack of a portfolio. You can build up a portfolio of theoretical projects which demonstrate your thinking, the process, and your ability to communicate. Have a read through some of the threads in the Careers sub-forum for more details on how to do that.
Not necessarily. If you have the ability to study part time while you work, and make sure you have some extra hours to put together a portfolio, I suspect you're just as likely to get a job.
I'll send a few other sets of eyes this way, to get some more solid advice around career paths.
