Contacted by recruiter about a week after applying online and set up a phone interview for the following week. Interview was fairly standard... asked me to walk through resume, described the role in more detail, asked basic interview questions.
Be sure to discuss how your skills and background fit into their leadership principles. The interviewer specifically said, "the fact that you already landed an interview means we think you're smart and can do the job. I'm more interested in whether your leadership style fits with us." He also mentioned that for the Manager level and above they look for "Bar Raisers" meaning that every new hire needs to raise the bar for that role across the organization. They are looking for people who can come in on day 1 and perform better than 50% of the people already doing that job. It's a solid measurement tool for an organization that's growing at such a rapid pace, but it also means that you may take a lower title than where you are now based on how you rank.
