How would you convince someone to buy a HoverBoard that actually hovers, If you were the person who made the product? (The product is called Hoverboard 2.0) (You're trying to advertise your product)

Get them maybe a discount or lower the price

no, a company likes to look at potential employees that are professional, well mannered, clean, honest, etc. don't show up looking/acting like a clown. (unless that's your job xd) hope this ! =^-^=

if it is for a job, then you should learn everything you can about the job, like what does it involve, what qualification is required and how you are the right person for that job. dress appropriately for the interview. get plenty of rest the night before. good luck!
