Intuit Corporate Strategy Manager interview questions

I was told that it's only a personal interview to get to know me and I ended up getting a case. Didn't appreciate it as much. It started with 10-15 minutes intros and then straight to case

I forwarded my resume to the recruiter. Apparently the hiring manager doesn't want to consider me because I don't come from a big 3 consulting firm(Bain, Mckinsey, BCG). Which is absolutely ridiculous. I'm interviewing with a number of other groups not having come from the big 3. At least conduct a case interview. From there, we can see whether I have that management consulting skill set. The recruiter then proceeded to waste my time, she set up a call under the pretense that we would be discussing this role. During the call she said the hiring manager had seen my resume and didn't think it to be a fit. Then why schedule a call at all? Total waste of my time. It's ridiculous. It doesn't speak well of the recruiter. And it doesn't speak well of the Corporate Strategy team and hiring manager. I do come from management consulting. I think it's ridiculous to not even give a non big 3 candidate a chance. Quite frankly, it's discriminatory. Overall, very disappointed in Intuit.
