8 out of 10. This is an honest answer and I will explain why. Just as the last answer (which I love the answer) I will add on to it. There are so many formulas and codes/commands, depending on your role, we need to keep a small cheat sheet in sticky notes or even paste it on the wall to get rapid results. Sometimes I’m running scripts in Linux/Unix, Selenium, or fetching a query in SQL. It’s good to have a reference doc/cheat sheet to keep you moving in fast pace. When I keep a cheat sheet I write whatever I’m doing, then check to see if I’m correct to see of I did it right. 90% of the time I write the correct script/formula and when I cross check, it feels like a pat on the back. Organization skills are a requirement, use them.
