Good, total 3 round of interviews, and every round has different sets of questions, 1 round- Normal knowing past experience 2 Round - Technical round related to job 3 Round- Why you want to join, how this profile is going to help you grow and all.

They see your confidence and how well you can speak, if you are confident enough with the right skill sets, you will get through it, however, I would recommend that before the interview you should have knowledge about B2C sales, how to handle customer on call, pitching and most importantly how edtech industry works
