A few days back I had a second interview with a European university on a project that I really liked. I have also another offer from a Canadian university and am still waiting for 5 other universities for a decision.
2 Hours after the interview I got the PhD job offer. The very next day I received another email from the department head asking me for a response for the offer I received less than 24 hours earlier.
While I really like the project and the people, I can not make a decision this quickly. I asked him to give me until the the beginning of next week and he agreed. Even by then, I cannot make an educated decisions because there are FIVE decisions that I didn't receive yet.
What would be a good thing to tell the professor by the the time I have to give my answer? I there anything that I can do to have more time before making this decisions ?
