Euromonitor interview questions

Phone interview with recruiter, then second round onsite interview with hiring manager, then third round onsite with two managers. Was asked to prepare for a case using Passport, engaged in a role play where hiring managers were clients. They expected much more in my presentation which would be very time consuming. Understanding every company wants best talents. I think it's too much asking candidates to prepare for more than 3 hours. This is a mutual selection process, if you cannot spend an equal amount of time on a candidate, then you shouldn't ask for so much. No asking of compensation on travel expenses.
