I have two pieces of advice about this experience: First, be curious. Always. Ask questions, seek to understand. Don't assume that everything is right the way it is. If something looks off, seek to understand why and be courageous enough to offer input. Second, if you're given a lot of autonomy, own it. Show people that you are dependable. Be creative in your work and show your team how it can provide value. There is rarely one right answer or one right way to create a model.
