You've already touched on most of the reasons I keep snakes. Here are my top five.
1. They're beautiful / amazing animals that have adapted and survived for millennia.
2. They're easy to care for and relatively inexpensive to maintain.
3. They're more intriguing than most other pets and are always a topic of conversation. People are either fearful or fascinated by them. Very few animals have the mystique of a snake.
4. They have a calming and soothing effect for many people. I often say keeping snakes is like bonsai to me. It's one of my favorite zen spaces.
5. The reptile community is filled with many wonderful people from diverse backgrounds all across the globe.
Best wishes in your interview brother!
