They will call you at the scheduled time. Then they will ask you really simple questions... even non-native speaker can easily answer them... The phone interview will only last about 10 mins.

The interview process was quite simple! Basically, you talk to one of the company's HR interns for your first interview as a screening measure. They ask you typical interview questions: Why you want to intern for the company, do you have any experience, strengths and weaknesses, etc. Once you pass that interview, you are scheduled for another interview with the company's founder Robert Braathe. He is an incredibly nice and easy to talk to guy, and he will tell you how you can get started if the interview goes well!
