The video brought me back to my internship in the early 2010s. My job was testing the new US ovens (which for us Europeans are massive). The bus was amazing. Integrated into a LabView setup, you could basically collect any readings from the oven as well as remotely control it. Also, it was super easy to confirm "manual" actions (e.g. soleniods pushing buttons/motors turning knobs).
A few other interesting tasks I was involved back then were:
- smashing an oven's door until the hinges would give up - testing new heating elements in the open (basically, building a gigantic grill) - appliance transport packaging tests - cooking and baking on a daily basis to make sure food turns out as expected
Overall, home appliances are a great product as an engineer to work on. It is a product you usually use multiple times a day. And if you love cooking yourself, even better :-)
