I have just received a job offer from mckinsey today. They wanted me to start in early july (about 1.5 weeks from now). My current employer has a 1 month minimum notice period for resignation. Should I accommodate mckinsey's date and possibly burn the bridge with my old employer or should I ask Mckinsey if I can start at a later date?
I know that McK urgently needs to hire someone and so my concern is that if I dont accommodate their date, they would give the offer to a different candidate? I currently have only received verbal offer via phone and not yet a written official offer letter
