At the English lesson...

I work in IT-department. Twice a week we have English lessons inside the company. At the last lesson, our teacher made the task for us. You need to hire a person. And the three candidates are equal except for their hobbies. One person likes to play basketball. The second person likes to play chess. The third person likes to play video games.
1. Which person will you hire to work if he or she usual worker (in my company, for example, it's programmer)?
2. If you need to hire a boss, which candidate will you choose?
3. Which person will you choose for a job of a microsurgeon?
We answered this questions and discussed. I chose the person who plays chess in the first two cases. For workers, it's useful because it develops analytical thinking. For the boss, it's useful because chess help to choose best strategies. For a microsurgeon, it is more useful to play on video games because it helps don't make mistakes and exactly to fall into a small area.
Please correct this text. And it is interesting to me, how can you answer these questions? And why? Thank you.
