No. They just wont hire you after the internship – maybe they'll put the offer but they'd likely let you show up since they were preparing for it already. Exceptions being a family or personal event causing it. Or you literally walk on water during the internship. When you go back into recruitment everyone will wonder what was wrong since everyone gets offers after their internships. They'll think you did nothing or pee'd on a partner's desk.
Quite frankly, you'll be worse off had you not gotten the offer to start with. Sorry..
I heard just a week ago about a person getting sent home. Wasn't an intern even – he had graduated and was starting full time. Believe he interned as well. He flew into town and was in his full time training class – they pulled him aside and handed him his ticket home…
Regarding your decision to drop. That should be based on how high you can get your grades considering you work your hardest – and if that grade would look better than a “W”
Some of us took 19 credit hours in semesters, such as myself…if you are in that boat they'd probably be more forgiving on a drop. But you also had to drop one of your accounting classes.
Get the course grade up. Or compensate with higher grades so you can speak to that if questioned.
I'm doing you a favor and making you serious – I had the same issue my senior year. Luckily, my grades didn't fall.
