I initially applied in late September by speaking with an engineer at an on-campus university recruiting fair and submitting my resume.

They reached out about a week later to schedule a phone interview, which took place another week later.

This interview was about an hour and a half long and was split evenly between behavioral questions and one online whiteboard coding question.

They then reached out that same day to schedule an onsite interview in SF, which for interns is always done in batches on specific "hiring days."

You should prioritize going to the earliest hiring day possible, as I believe they hire on a rolling basis.

I chose one for that same week.

The onsite took half the day and involved two one-hour interviews with an engineer.

About a week later, they called me and extended an offer.

The entire process took roughly 3-4 weeks.

(Onsite)

Design, at a high level, a way for hosts A, B, and C, which are connected via the internet, to communicate such that A and B can talk to each other, and B and C can talk to each other, but A and C cannot.
