Offer received with other final interviews pending

By | October 17, 2017

I received an offer from one of the Big 4 firms and still have final round interviews with two of the other Big 4 firms next week.  Should I mention that I received an offer from the first firm in the interview or would that hurt my chances of receiving an offer from the other firms?  The firm I got an offer for was my second choice so I’m still hoping for my first choice.
