I applied online and was called in 3 days. I had a phone interview first where they described the job responsibilities, then gave me an appointment time. Standard interview. The one on one interview was at their corporate office in Houston. Tell me what you did at your previous jobs. Your Strengths. Your Weaknesses. Where do you see yourself in 3-5 years. What was a mistake you made at work and how did you learn from it. I was nervous but the interview was not hard. Very friendly person. Lasted 30 minutes.
