Is anyone who's experienced with case interviews willing to give me 2 interviewee-led cases (one medium, one hard) and give me brutally honest feedback?

Hi everyone - I'm a senior going through FT recruiting for management consulting roles and I've been rejected from first-rounds at a T2 and MBB, in addition to this one other firm.

I believe I'm pretty bad at cases and have actually never passed a case interview (except for one with CarMax, which is not really about cases but rather about just setting up the right equations). 

I met with a case coach who is a recent grad from my school and he said I wasn't too bad, but just needed to fine-tune my answers (being more detailed with frameworks and communicating my math processes better). He said I was actually in a good spot to get an offer despite me NEVER having passed a case interview, ever! I don't really believe him, because the case he gave me was pretty easy and it was interviewer-led (McK style), so I think my performance there may have been incorrectly represented too positively. 

So I was wondering if anyone was willing to give me 1-2 virtual case interviews and an honest opinion of where I stand. 

EDIT: Just learned that I passed a case interview for the first time in my life but would still love feedback!
