I applied online and received a phone call from a recruiter within a week. This was just an introductory interview.

In the next three weeks, I had two technical screening interviews.

I passed the first one but did not advance after the second.

There were no resume questions; it was straight to the problems, and I shared my code in a Google Doc.

They were very kind and patient in general and could be helpful if you were on the right track.
