I applied online and sent my resume to a recruiter on a Monday morning and heard back within one or two days to have a 30-minute phone interview. I had a positive phone interview on Thursday morning that same week and later that same day, I was invited to do a program assignment, which I finished and submitted the following Monday. I was notified on Thursday that I was not selected for the position.

Interview process was easy, take home problem was hard. Make sure you dedicate some time to it and make sure it works. Don't assume anything about the information they give you. It is important to get it done efficiently but do not breeze over anything.
