Welcome to the wonderful world of being evaluated. The odd thing is that they are both right, at least partially. Different things work well for different people, and what each told you undoubtedly works well for them. So take both pieces of advice, and try them both. See which one works best for you, then put that one in your bag 'o tricks and quietly leave the other aside. Or, if they both work well, then double-bonus, toss 'em both in the bag. But either way, listen to what the evaluator has to say, thank them for their time and effort on your behalf, and never ya'butt
So... did you get moved up?
