I am not a classic profile you would think of for Management Consulting as I am a mechanical engineer and I have worked prior joining McKinsey. This gives me a good perspective on the differences between the consulting world and the industry and I could share it with you.
While being at McKinsey, I have done tenth of interviews for various position (from Summer Intern role to Project management role) and I know exactly what's critical for succesful interviews (personal case experience and problem solving). For the personal stories, I would be very excited to hear about them and to advise you on how to bring it to the next level. In terms of problem solving, I could help you to prepare on how to handle them and use my personal cases.
Looking forward to talk with you.
Kind regards and all the best
