Across several years of coaching and mentoring aspiring consultants, I have coached over 80 students to consulting offers. While I am an MBB specialist, I also have experience with the interview process of every other large consulting firm and a handful of boutiques. The case interview process is highly similar across firms, so happy to help with whatever firms you're targeting. 

I offer help with literally any part of the process for both experienced hires and current students. Feel free to ask questions or request any type of help, but these are usually the 3 areas I spend my time coaching: 

1. Landing an interview (networking, getting referrals, getting on the firm's radar) 

2. Impressing in the behavioral (very firm specific--McKinsey's PEI is the most infamous and I'm a specialist at this) 

3. Acing the case interview (also firm specific, but casing strategy is more generalizable)
