I was given a referral by a current employee at the time, so I can't speak to the response time of recruiters to applications submitted online.

After the referral, I was reached out to by an internal recruiter who quickly got me in touch with the hiring manager.

The hiring manager brought me in for an on-site introduction and an informal "are-you-insane-or-not" screen.

After that, I received a small coding challenge which took about ~2 hours of total work to complete.

The hiring manager was on vacation the week I wanted to submit my coding challenge, but once they were back, they had it reviewed and scheduled an on-site interview within about a week.

The on-site interview was with three software engineers and two managers, one of whom was the hiring manager I had been speaking with already.

The interviews themselves basically boiled down to four informal conversations with the engineers and one of the managers, and a very high-level technical exercise with the other manager.

I was given an offer immediately after the rounds of interviewing.
