I had an offer in hand from Company A. I'm in the final round for five different positions, but reached out to my top 2 - Company B and Company C - to see if they could counter. Neither could make a decision by the deadline of offer deadline (it was an absurdly quick turnaround), but both worked to see what they could do to move things along. I turned down Company A's offer (for professional & personal reasons) and informed B & C.
Now about 2 weeks after the initial offer, I have an offer from Company B. I'm happy with this offer, but Company C is still my top choice. However, it seems desperate and rude to turn around to them again and say "Hey! I have another offer - have you made a decision yet?" Is it appropriate to ask Company C to counter again (am I even in a position to counter), and if so, how would I frame that ask?
