Getting offered a PhD and ither interviews now loom

S

Hi,
I was recently offered a very interesting project. One which I have a good mind to accept. But I have applications for projects still outstanding, and another interview now looms. Given that interviews are initially expensive (even though I can claim the money back) and not the most enjoyable experience, should I pull out from the interview, or go along, at least for a point of comparison?
Tis a dilema
