Target HR Representative interview questions

Applied online, received a phone call to schedule a phone interview 3 days later. Phone interview asked basic interview questions, lasted 15 minutes. Then had to complete extensive online testing at home--tested math skills, reading comprehension, personality test, etc--took about 2 hours to complete. Next had to drive 3.5 hours for an overnight stay at a nearby town for first round of in person interviews. They were panel interviews and lasted 4 hours, met with bigwigs, etc. A week later got another call to meet with the CEO of the local distro where I would be working--as well as with the HR director. Two days later had to meet with the HR dept. managers as well as complete another computerized test and drug test. Was paraded around the HR dept to meet all the associates there. After all that, they decided to offer me a job that was actually lower on the totem pole than the one I applied--and was qualified--for.
