Had a helpdesk job. They apparently used to use a very old almost CLI-like interface, but wanted to fase it out to use salesforce. But they still let the seniors at the job use the old interface, while we had to use the new salesforce system.

Which meant that, whenever I had a problem doing something and went to a senior colleague to ask for help that that'd fix it in the old UI, because they never bothered to learn to new one. Which meant that I wasn't learning critical skills in the new UI, and that they weren't learning it at all.

Dumb all around. Quit after half a year for different reasons but that one didn't help
