This question already has an answer here:
I'm involved in a coop program at my school and after receiving a job offer, you must accept it in 24 or it is considered to be declined. I received an offer today from Company A.
Previously I'd interviewed at Company B, where I'd much rather work at and they said they would let me know the result of my interview this week.
Should I call the student program coordinator at Company B and let them know of this situation and ask them when their decision will be finalized?
