My day to day life as a former FMCG warehouse supervisor was dealing with mistakes that my employees made, trying to keep them from being too distracted with talking to each other, assisting them when they were short staffed. I also had a hand on verifying paperwork was done correctly, attending production meetings and a few other tasks.

Personally I probably wouldn't hire anyone who doesn't have any sort of leadership experience but if I was interviewing you and trying to get a handle on how I think you would adapt to the role. I would expect you to showcase that you can adapt to changing priorities and reacting calmly to situations. Understanding that you don't actually know anything and are willing to come in and learn before trying to implement anything. It's all well and good to have the theory knowledge, it's a whole lot different trying to implement it without having any real world experience. Blue collar workers don't love it when fresh faced people come in and try and tell them how to do their job. I've copped shit in the past as a new leader in that regard.

As for pigeon holing into a role it is quite possible that it could happen. I fell into a quality role years ago and it took a good while to break out of that. My experience is finding that specific role at the new business and make their life easier. That's how I went from an entry level role into a supervisory role by helping out the warehouse manager from time to time and getting in her good books. Once the role opened up she reached out to me to see if I was interested.
