In certain situations, you may be made a verbal offer. You may accept the offer over the phone; however, you must follow up with a written acceptance letter to the individual who has extended the offer. If you are made the offer during a second interview, you still must follow up in writing.
After accepting a co-op or internship — even if the acceptance has been only verbal — you may not consider other offers.
Once you accept a job offer, inform other employers with whom you have pending offers.
NOTE: You MUST cancel any other scheduled interviews or on-site visits once you have accepted your co-op or internship.
