Pros
Compared to competitors AZ is a good company to work for except in Memphis. If you negotiate well enough during the hiring process you will be well paid, company benefits are above average, AZ did not cut 401k match when many other companies did and the company is strong financially so you do not need to worry about having a job from day to day. Working conditions vary from store to store and depend mostly on how well you choose to get along with middle management.
Cons
Being the corporate headquarters, everything here is over analyzed and over-reacted to. The entire region is ran by the HR manager who can make life very miserable for you if she does not like you for any reason. I really enjoy my job and like would not have left the company except for the fact that one mean-spirited person can cause hardworking and well-intended people so much grief any time she chooses. Like several others that I know, she completely ruined my job and made my time at AutoZone miserable.
