J.B. Hunt Transport Operations Manager Trainee interview questions

(Ex-Military guy looking for a position as a Operations Manager Trainee) I went to three interviews. The first was with two Operations Managers from the Dallas area. The second was with a Regional Manager and the third meeting was with a DCS Account manager. The first round of guys asked the same old questions, "why would you be good at this job" "why wouldn't you be good at this position" "what are two of your weaknesses" those kind of things. The second round was more of the same with a Regional Manager he was very quiet and waited for me to talk myself out of a job... I felt like I bombed that interview but I was surprised to get a call a few hours later telling me to interview with another local Operations Manager at a DCS account site. The DCS Operations Manager asked the same things as the others except he asked about my Microsoft Excel skills and ability to multitask if needed. I was given an offer of employment a week later for an Operations Manager position at that site, not the trainee position. Background and hair follicle drug test within 48 hours of signed offer (0.5-1.5 inches of hair needed in my area), 50K starting salary, quarterly bonus potential (probably 1-2K max per quarter) 2 weeks of vacation and two personal days after a year of being there, half of 401K match up to 6% after a year of being there, medical insurance effective after 90 days on the job... Pretty crappy benefits package if you ask me but hey it's a job right?
