Moët & Chandon interview questions

Recruiter asked how much my client book is worth. To me that is a personal question as it's my own business. Also, why are they expecting to bring my clients. I don't even work in the alcohol/beverage industry. Recruiter mentioned something about selling $30k case of alcohol to a customer. If that's what they expect, they should be bringing on their own clients. Seemed like they just wanted to make money off my contacts.
