This: "Do what you said you would do, when you said you would do it, the way you said you would do it." That to me is 90% of success - the rest is passion and developing your skills so you're good at what you do, and knowing when to say no. But all that is BS if you don't follow through on commitments. Over my career I've been amazed at how often people don't show up, in either a physical or virtual sense.
Sounds like a fun interview.
