Before jumping to "Duplicate" as found here:
I really thought this was an appropriate question given my circumstances. I have recently accepted an intern position with my first choice company. Key point here is that this internship is clearly stated to be temporary only.
Earlier this week I had a phone-screen interview with another small company that seemed really enthusiastic to bring me in for a face to face interview. Of course I must halt this interview process, but I am actually quite interested in the possibility of either applying to this job after graduation (in 2 years) or interning with them next summer. Of course I never explicitly received an offer, but should my "Thanks for your consideration, but I'd like to withdraw my application" email look any different than a "standard" no-nonsense withdrawal email?
