Hello,
I have some doubts about my story for the Personal Impact area in the PEI at Mckinsey. I am graduating undergrad this year from the UK (3-year degree) but the story I have prepared goes all the way back to my time in high school. I am confident the context works perfectly but given that this is the only time that I really convinced someone senior regarding a major issue, I am limited in my option of stories. Would this be looked down upon (i.e asked for a different, more recent story) or would interviewers understand my lack of interaction with more senior people in this specific setting (convincing them of my viewpoint) given my age and non-professional background?
