Ecolab Route Sales Manager interview questions

Submitted a resume' online via monster.com. Received a phone call from an Ecolab HR recruiter 3 days later. I spent 1 hour on the phone with them 2 days later interviewing for the company. It was more or less a screening for an interview to judge if I was intelligent and had adequate people skills. I was told that I would be hearing from a District Manager in a few days to set up an interview. 2 or 3 days passed by and received an email from the DM to call him so I could set up a time to interview with him. The interview went very well and the DM was very professional but made me feel comfortable.I was then asked to interview with the Area Manager a couple of days later. I was then asked to take a physical and drug screen. I was hired roughly 3 weeks after I applied for the position.
