I am almost certain that I will receive an offer from a very prestigious company. I have currently been at my job for about 9 years but the opportunity I am about to receive in this new role is one in a lifetime and not to mention more money. The thing is that I just recently found out that I am pregnant. Should I tell my future employer before receiving the offer letter? Should I wait to tell them after? Or should I stay at my current position where I am stable and have more flexibility?
