Got an unexpected phone call with a pre-interview that lasted approx. one hour. Scheduled an on-site interview and completed background check materials. Met with 3 people, each one hour, to discuss my resume, experience and ambitions. All of them where incredibly forthcoming and nice, answering my questions about the position. Was asked to email a two paragraph statement on why I wanted the position and on a fulfilling personal experience by the same evening. However, there is an extensive background check which lasts over a month but HR people are incredibly helpful and will help you with any issues/questions!
