Hi Guys, I recently got an offer too- it was my first interview and the PhD I really wanted, so I'm dead chuffed. This website and comments certainly helped. Looking forward to October now! (I'm sure I will hate the PhD sometimes too in the future though). I think the research environment you will be in and how you interact with people there, and how their fields relate to your interests, are almost as important as the PhD topic!
p.s. I haven't posted on here before, by the way. And good luck to all those waiting for offers and interviews! Will certainly continue to use this site.
