I recently received an invitation for an interview for Amazon SDE Summer Intern 2021. I completed the survey, but I misread the instructions and only put down one time for avaliability. I emailed them about the mistake, but its been 5 days and I haven't recieved any updates. Should I be worried?

Also, what are the best topics to practice for this interview and how will this interview look like. This would be my first interview ever, so any general tips?
