Interview

I have been going to some interviews recently where some sales Vps and leads have been asking questions like: 

After they see my performance results and references. 

"Tell me your secret, how did you achieve this?"

"what is your sales process, what the secret? Tell me Tell me"

I am wowwww, hang on a second. There is no secret. I mean I can recite the usual information you'd find on Sandler or meddic but you know that already. But I thought this was an interview not a paid consultation on sales?  

It seems like some think there is some "secret" while each deal is different, products are different and people are different. The rule of sales apply to nearly everything but don't fish for information from candidates if you are not hiring them. 

What I find rude is when they feel they are the only ones entiteled to ask questions and then at the end never allow to ask questions or simply be polite and present themselves.

How have you handeled this?
