What does Emery discuss with head coach candidates?

So I've been asked a lot about why Phil Emery is interviewing so many different coaches for the Bears vacant head-coaching position.
The purpose of talking with so many guys is to simply learn as much as possible. Whether it be offensive systems, philosophies or even to learn about other assistant coaches, there is a method to the madness.
Head coaching interviews are as detailed or more than any job in sports.
Some key topics that are always discussed include systems style on both offense and defense. Since most of the coaches being interviewed by the Bears are offensive guys, they may lay out a good chunk of what they do in terms of utilizing personnel and overall system. Some coaches will have an entire PowerPoint presentation.
One thing every prospective head coach brings to an interview is a long list of potential assistants he would pursue to join his staff. He may include dozens of guys since many may be under contract and unable to leave current jobs. The list is dissected by the general manager and there even may be coaches the general manager may say he won't accept for various reasons. This is also a way general managers learn who the highly respected assistant coaches are by seeing the same names pop up on different lists of prospective head coaches.
Other topics sure to be open for discussion include: How do they practice, meet and discipline players? Often times a coach interviewing will have an entire mock practice schedule for the season. Responsibilities of the assistants, does the head coach play the role of the CEO and allow his coordinators to run their sides of the ball, or is the coach going to be a play-caller and over see his expertise?
The size of the staff is also a hot topic. Can the head coach have assistants to assistants which many teams do nowadays, such as an assistant defensive backs coach or offensive assistant, which are not quality control jobs? How many video people are on staff? What about the size of the training staff and other support people? Salaries of assistants has become more important. Many teams pay their coordinators at or near the 1 million mark and top assistants around 500 thousand.
In the Bears' case, the subject of Jay Cutler will no doubt be debated. If the head coach isn't sold on Cutler after a year he may want to know if he's tied to him for the long haul. The new coach may want to draft a young quarterback or look on the market for a possible future replacement. Despite being considered a franchise quarterback, any good coach will see the number of coordinators he's had and also look at his production.
The new head coach will certainly want to have some say on personnel even though Emery will have the final say. No coach wants to feel helpless when it comes to the players he's given.
I could go on and on, but that's just a small amount of what takes place during a head coaching interview. The more people Phil Emery talks to, the more information he gains, which helps him to make an informed decision.
It's a much better formula than picking one guy and saying, "That's my guy..."
