I was referred by my friend and was instantly placed by a recruiter for a senior position. I wasn't looking to fill a senior role, as the stack was a bit different from what I was working with before. I had one phone interview. Unfortunately, it was

Initial phone screen. It took about a week for them to get back to me after I submitted my resume.

Two tests of one week duration, as many interviews as they think they need. The bad part is the process isn't very clear from the beginning, so you may have more or fewer interviews depending on what they could evaluate from the previous ones.
