Example of behavioral question: tell me about something you have learnt in your job. Example of code challenge question: given an array of ordered strings (with some empty strings in the middle), return the index of a given string (which may or may not actually be present in the array). Usually, the questiosn aren't too difficult (no smart gotchas), but they expect you to present a very structured answer (they want to know about the outcome of the situation you presented in the behavioral questions, or some discussion about the code you wrote - time complexity, space complexity, how to improve your code, maintainability, optimizations, tests, limitations, etc.).
