I've faced 6 months of no job offers and now I am getting ready to move to UW in Seattle to start my full time graduate position, and I have just been offered the two part-time jobs I applied for there. When it rains, it pours.
The first job I got offered 2 days ago, I accepted because I just assumed I wasn't getting the other one since it had been about 2 months since I had heard anything, and I was so used to rejection. The job I just accepted is a one year long, casual part time position working on a career blog and a career fair with the school I will be attending. It's a year long position and fits my outreach work experience.
Then what! 2 days later, I actually DID get the 2nd job. The thing is--this one is a research assistant with a professor doing EXACTLY the kind of academic work I am interested in. It pays $2/hour more than the former, but only goes for 6 months (with the possibility to extend.) It would obviously be way more prestigious, but both are fitting to my interests in different ways. The professor would also be my advisor and help with my classes/thesis prospects.
Since it's only been 2 days since I accepted the job offer, I'm sure it's not too late to back down. I just really don't know how to phrase that.
Looking back, I KNOW I should of waited but what's done is done.
TL/DR: How would you phrase the refusal of a job offer you've already accepted? Would you take program assistant or research assistant? Have any of you had similar situations?
