I have a friend who is unable to find a job in the industry. He's a fresh university graduate. He's now applying for a PhD position because he's found a supervisor. I have every reason to suspect that he wouldn't enjoy the degree because:

* He's very good at memorizing text-books and past-exams, but never able to come up with a solution independently.
* He doesn't enjoy reading unless it's required for exams.
* He plays and socializes a lot.
* He came up with this idea after failing some job interviews.

I think he just wants to go back to university because job interviews are tough.
