PepsiCo Mrchandiser interview questions

I applied online and got an email a couple of days later to schedule an in person interview. Went to the warehouse and met with a manager. She gave a brief intro to the position and went over the exercise I would be performing as part of the interview process. She then pulled up a video for me to watch that went into further detail about the exercise portion of the interview. That lasted about 15 minutes or so. I filled out some paper work releasing liability from Pepsico if I were to injure myself during the exercise. I was given a plan o gram to look over and then told to follow her to the warehouse. The exercise consisted of using a pallet jack to move a pallet of 2 liters to a spot, offloading the correct amount onto another pallet and then moving that pallet to the other side of the warehouse, where I then began to merchandise the 2 liters based off the plan o gram. A couple of minutes into doing this, the manager came over and gave me another plan o gram and said this is the new layout I was to follow. This is done to throw you off and mind you, this exercise is timed at 15 minutes so you better move quickly and efficiently. The manager will be there watching you with a timer the whole time. They are looking to make you you use proper lifting technique (ie; bend at the knees not the back, only lifting so many 2 liters at once, etc.) and finish in time. I ran out of time and did not finish the exercise completely. Once that was done, we walked back to her office where we did the interview portion. This was a one on one interview and lasted about 25 minutes. Pretty standard stuff and I answered in the STAR format. I was told I would hear back from them within 2-9 days regardless if I got the job or not. This did not happen. In fact I called the useless Pepsico HR twice and got canned responses both times. I checked the Pepsi "Candidate Care" website everyday and didn't see a change until a month later when I learned I did not get the job. I found that to be very unprofessional.
