I think my job interview is scammer

in my interview they have been ask me few simple questions , then i was approved ..interview was via Skype.

they asked me to buy Versa checks, was asking how much credit balance do i have in my Credit card. i keep an option of payment with pay pal, they said we can transfer it in your credit card. they will reimburse the money to my account what i purchase with versa check.

i doubt weather its a legit company.
