I have an internship offer from a good tech company (A) that is about to expire and I cannot ask for an extension. However I am still interviewing with a better company that I really want to work for (B).
I don't want to decline the offer since I am not totally confident in my ability to get the offer from B.
However the terms of the offer from A states that "[this] is at the mutual consent of you and A, and is at-will in nature and can be terminated at anytime for any reason or no reason ... can only be modified in a writing signed by A's Vice President of Human Resources."
The internship from A starts in six months, so should I accept it and later cancel it if I get an offer from B? Will I get a bad reputation that will affect my later career?
