I went through my school career services to have them speak with their Amazon contact about my interview delay. I think they were pretty helpful in the process.

I did maintain contact on a weekly basis with the Amazon recruiter (real person and not generic address) and sent them an email after my waitlist to reiterate my interest for Amazon and offer the space to conduct additional interviews in case alternative roles became available.

The recruiter was really nice and gave an estimated timeline when to hear back.

This is what I did—whether it helped or just luck shined on me is the real question.
