PlateJoy's questionnaire is extremely thorough, so you can be sure your meal plan will actually be personalized. They ask questions you would expect to find when creating a healthy eating plan, like if you're trying to lose weight, how active you usually are, and what ingredients you're looking to cut from your diet — if any at all.
You'll also be asked very specific questions like how you feel about seasonal produce (do you care if your meals include out-of-season ingredients, for example), eating leftovers, and if you prefer batch cooking or having something different for dinner every night.
You can go back and change the answers to your questionnaire at any point, in case you realize something you choose is not actually working for you.
