I'm still working at my current job and will be done in one week. I'm wondering what is the typical way to go about asking someone to be listed as a reference on my future resumes while I'm still at my current job.
I'm working as a summer intern at a job to build up my resume; I've got about a week left of my job and I would like to ask my supervisor to be a reference on my future resumes. Is it typical to ask someone to be a reference by email, or should it be done in person?
I'm mostly wondering because it seems to me to be of bad form to ask him at work since it would be in front of other people whom I didn't ask/it kind of puts him on the spot.
Also, is it considered poor form to ask for the reference a week before I'm actually done? am I supposed to ask after I've already left?
