I have helped interview at my current company which is a Fortune 50. Typically it is split depending on whether the person is more senior or junior. Since you mentioned college I’m going to assume you fall somewhere on the junior side of the scale.
For junior positions I am mostly looking to see that the person is eager to learn and has a good mentality. This means that the person doesn’t have a huge ego, talks passionately about projects, etc. red flags would be not knowing extreme basics like functions or variables. IMO for junior positions culture fit is way more important. I want someone that will learn and grow with the team.
While I can’t help with recommendations for all of your interests, for climbing I recommend Magnus Midtbo, Adam Ondra, and Daniel woods and co “mellow” channels. Usually from those three I can find high quality climbing content via recommendations.
I always use my left hand. My left hand is quite dominant on my keyboard. There are only a couple keys that I use my right hand for. fwiw I can type reasonably fast.
