Having worked with filling shelves, that job felt sometimes a lot more complex than my development job nowadays. The store I worked for didn't in general allow anything extra to be stored in the warehouse. This lead to the filling load sometimes having excess products that you had to fit somewhere. I really enjoyed making space by moving and rearranging products on the shelves. The products came in wrapped in big rollers that contained random products so looking at the roller product list and how they were packaged you had a puzzle to find a nice path that visited all the correct shelves. Occasionally you would have campaigns and such where you could be quite creative in setup and arrangement.

It was the job I have been most satisfied with in my working life. However, I did only do it for 8 months for 6 hours a day. Maybe in the long run it gets more boring.

The variety between shelf filling between different store brands and even different stores of the same brand made me really think no two jobs are the same.
