Dental student wanting to do internship

Hi there,

I will be entering my third year of dental school soon, and I've been looking into consultancy over the last few months. I'm interested in internships but unsure how to apply as a dental student.

A bit about me: I'm based in London, UK, and I study at King's College London. My pathway is a bit unconventional: prior to dental school, I worked as a waiter and did accountancy work for 5+ years (still do accountancy work during the summer). I'll admit my school grades are less than desirable due to past personal difficulties, but I'm happy to say I've managed to turn things around and I'm so grateful to have gotten into dental school and managed to pass exams first time so far (the grades aren't anything amazing).

So, I want to ask, because my grades aren't anything exceptional, is there any chance of getting into an internship such as Bain and Co or Mckinsey? Thank you for your time
