Hey Nina,
I actually just had my
SEO interview this afternoon. It went great and wasn't scary at all. Don't panic. Stay confident. Talk slowly.
My phone screen was with a recruiter a few weeks ago. It was about 10 minutes long and was more informational than interview. The phone screen was pretty standard and my interviewer told me to expect an in-person interview invitation in the next two weeks.
What program are you applying to?
