Hi there,
First of all, congratulations on landing the interview. Great job!
Usually, internship interviews will be scheduled during regular business hours on a Friday but this can vary depending on specific logistics for your interviewees. Your best bet would be to proactively communicate your concerns with the recruiter that you have been in touch with to ensure that you can resolve any potential conflicts before they arise or that you’ll get visibility into it as early as possible.
Please feel free to contact me if you want to have any further discussions on how you can best perform during the day of your interview.
