Decisionlab interview questions

First I applied online, the next day they asked me to send them my grades. Usually, if emloyers are communicatng with you, then it means they are interested in you. They called on the phone 3 days after the application for an 1/1 interview. They asked questions like "If you have to sell grills how would you plan the number of grills you can sell? how do you calculate?" In which stage of your studies did you learn statistics? and in the end do you have any questions?
