I want to learn business one point topic

If you give me a topic, I will prepare based on that topic.
I’d like 1?2 topics per lesson, preferably related to business situations.
Topics like interviews or business etiquette conversations are great.
In the past, I used material from this Monster.com article(https://www.monster.com/career-advice/article/project-manager-interview) for my lessons, and I found it very helpful.

thank you
