My First Job Offer

I just had my phone interview with the EG Language Institute in Junggae-dong (that's in Northern Seoul). They offered me the job, and as of now, if I accept it, I need to leave no later than June 28th. I need to talk to my recruiter and make sure that this is really the school for me. If I do take the job, I'm gonna try to squeeze and extra day or two out of them so I don't have to leave quite so fast.
