Got a quick reply after applying online, scheduled a phone screening for the next day. I had an interview with 2 people. They were very straightforward asking me specific questions about tools I use and what results they are bringing. In the end of our phone conversation they requested samples of my work and analytics which I provided the same day. Never heard back, even though on the phone conversation was quite pleasant and promising. I find it unprofessional to leave another person to hang in there without letting him/her know despite the fact that I tried to follow up several times.
