Referral from internal employee is always going to make things smoother. Had a phone interview with hiring manager to get to know each other, fairly informal. Afterwards, I had one face to face interview where we went through the standard expected questions for a first face to face, but again, with an internal referral you'll make life easier. Just come prepared as you would expect and you won't catch any curve balls

Four interviews total. Not very difficult. Typical questions. Give examples of sales success, situations, etc. Traveled for the last interview with multiple managers, human resources. Traveled for the last interview with multiple managers, human resources.
