It's important to cover all of these aspects when introducing yourself in an interview, as it helps the interviewer get a better sense of who you are.

It's important to acknowledge that everyone has weaknesses, so don't say that you don't have any. If you're unsure what to mention as a weakness, you can discuss one of your strengths from a different perspective, such as being too focused on problem-solving, which can sometimes lead you to overlook other important factors.
