At plated we do two coding interviews. The first is concrete, we have a library that is poorly written and their job is to implement a new feature and refactor it. This is a great interview to understand core skills. The second interview is a modeling exercise where we build an app from scratch with escalating amount of complexity but only asking for what the database and api endpoints would look like.
