interview question help for postion at an adult store

im not super great at coming up with answers and questions during interviews because i tend to get so nervous, but recently ive landed an interview at an adult toy/420 supply store. im a pretty friendly, respectful, and non judgemental person who has worked customer service based positions before, i also have a fairly decent knowledge on all the product id be selling. im just so bad at answering question like, tell me about yourself, why do you want to work here, what makes you qualified, etc. any help with this would be greatly appreciated!
