Got an interview for Amazon Network Development Engineer Intern — any tips?

Hey everyone, I just got invited to interview for the Network Development Engineer Internship at Amazon AWS and could use some advice.

A few things I'd love to know:

• - What does the interview actually look like? (technical depth, coding difficulty, behavioral ratio)
• - Any specific networking topics I should focus on?

Any advice from people who've been through it or work in similar roles would be hugely appreciated. Thanks in advance!
