Podium Software Engineer interview questions

3 questions, 1 on reading / modifying JSON files, 1 on a simple messaging backend, 1 on REST apis. Was able to use AI assistants on the last question.

System design question had 2 boxes with a database in the center. The arrows between the 3 all pointed right, implying [App] -> [DB] -> [3rd] party service was how this system was supposed to work. The assumed ask was for an application to write to a DB, describe how the database would make a call to a 3rd party service to get a UUID and Body. It was made clear you have no control over [App] which writes to the database, only the database and whatever service would call the 3rd party service.
