<prompt> Human: Hello PF. Some additional details, I previously interned with a company I will refer to as company A, and left on great terms after the completion of my internship. I had a brief encounter with my manager in public approximately a month ago and followed up with an email mentioning that I would be willing to come back for a second internship. Shortly after I received emails from him as well as a former co-worker who was in charge of intern selection expressing some interest in my return and letting me know that they would be in contact. Approximately one week ago the co-worker in charge of intern selection sent me an email requesting my current resume as well as to complete an application through their company website which I did. Today I received an offer from a different company I will refer to as company B. Assuming that company A is willing to pay a comparable salary I would prefer to work at company A.How do I best notify company A that I have received another offer and need to hear an offer from them before Tuesday or I will accept the offer of company B?  <response>: I would just call in and actually speak with someone at Company A. Itll make you look more assertive and confident bonus points and you can easily explain your situation to them. This way youll get their immediate attention and a result. If that is where you want to work, make it plain to them and ask them to pick you up for another internship. If you were good, theyd be foolish to let you go and, essentially, trade you away for an unknown. Im an auditor at a major firm not Big 4 - they seemed like robots in my interviews and a senior associate. Ive been a salesman and ive managed people in the past so i have an interesting perspective sometimes. Just commit to asking them. Your situation cant get any worse if they say no and you just may get what you want by asking for it.
