   • Don’t Ignore Feedback: If the interviewer provides hints or feedback, take them into account and adjust your approach accordingly.

   • Avoid Negative Talk: Don’t speak negatively about past employers, colleagues, or experiences. Maintain a positive demeanor.

8. Don’t Be Unprepared for Practical Demonstrations

   • Don’t Underestimate Coding Platforms: Familiarize yourself with the tools and platforms that will be used during the interview to avoid technical difficulties.
   • Avoid Ignoring Time Management: Be mindful of the time allocated for each question to ensure you can address all parts effectively.
