I accepted an offer from McKinsey towards the end of my Bachelor's degree and would be starting in a couple of months, possibly from home due to COVID. I took a gap year after high school to start a packaging business which is doing just fine - however that meant that when I graduated I was 24 years old. I am worried that I would be one of the older undergrad recruits at McKinsey as generally fresh grads are around about 22 years of age. Would I feel "old" among my colleagues and out of place? Or am I overthinking? Thanks a million for your help!
