Gap Inventory Planner interview questions

I applied for several Inventory Planner positions at gap via their website. Within two weeks I heard back from two different recruiters and set up a a phone interview. During the phone screen, I spoke with 2 different manager, for about 30 minutes each. The recruiter was very helpful and I spoke with her before and after the phone screen interview. The next day, the recruiter called to set up a time for me to come in for a more formal interview. That was a couple days later. I met with 5 different people, pretty exhausting and long interview process, but super challenging. I would make sure that you review Retail math, because a simple retail math question could come up
