It's inevitable that you'll receive some negative feedback during an interview – but don't let it get the best of you! Here are a few tips to help you stay calm and confident.

Negative feedback can be discouraging and frustrating. It's natural to feel defensive when someone critiques your work, but it's important to remember that the feedback is given to help you improve.
Before you can work to improve your work, you need to understand why you're receiving the negative feedback. Sometimes the feedback is valid and points out genuine flaws in your work. Other times, the feedback may be based on personal preferences or be inaccurate.
It's important to be able to distinguish between the two types of feedback so you can focus on improving your work. Valid feedback should be addressed, while feedback based on personal preferences should be ignored.
Correcting the flaws in your work will take time and practice, but it's worth it to receive the positive feedback that comes with improved work.

When someone rejects your offer or proposal, it can be easy to take it personally. However, you need to remember that the other person may have a valid reason for saying no. It's important to stay positive and keep your composure, even if you're feeling disappointed.
There are many possible reasons for a rejection, so don't automatically assume that you did something wrong. The other person may have already accepted another offer, or they may not have the budget to afford your services.
Whatever the reason, don't let a rejection get you down. Take a deep breath and move on. There are plenty of other opportunities out there, and you'll find the perfect one for you.

Negative feedback can be tough to take, but it's also an opportunity to improve. If you're not getting the results you want, it's time to take a step back and figure out what you're doing wrong.
Start by evaluating your goals. Are they realistic and achievable? If not, it's time to adjust them. Then, take a look at your methods. Are you using the right techniques and strategies? If not, it's time to make some changes.
Finally, don't be afraid to ask for help. There's no shame in admitting that you need some guidance. A coach, a mentor, or even a friend can offer valuable insights that can help you improve your game.

Thank the interviewer. Thank them for their time, and thank them for considering you for the role. Thank them for the opportunity, and thank them for the chance to learn more about the company and the role. Thank them for anything and everything. Thank them until you run out of things to say. And then thank them some more.
