Online application, phone screen, and in person interview with several team member. The process was a bit long, but seems to be the norm these days. Everyone was friendly and professional. However, the senior copywriter was one of the interviewers. He was overly critical and extremely rigid. He didn't seem flexible or open minded. All and all it was a drawn out process, but not intolerable. The company seems great and the folks are highly professional. But my advice is to make sure you are the most perfect you can be, as some interviewers on the panel are extremely critical and rigid; having his or her own way of doing things. It's their way or the highway. So make sure you conform to the standard and have a flawless resume. I was rejected for a couple of style concerns on my resume that didn't conform to the senior copywriter's standards or preferences. Make sure you have your resume in AP style and it is flawless. This will decide whether you get an offer or not.
It was regrettable that there was not a writing/performance test or perhaps some actual measurement of an applicant's skills. It seemed all a bit whimsical and left in the hands of a mid-tier employee, simply a very subjective interview process.
