Question - UNEXPECTED QUESTIONS
Answer -
Interview questions and answers can only be predicted and prepared for to a certain extent. There are endless variations and no way to know every question in advance. But that doesn't matter. Because you know there will be unexpected questions, you will not cringe or freak out when they pop up, as some applicants will. Instead, you will turn them into opportunities to shine even more brightly.
No one knows you better than you. Memorize a list of your best features, your best selling points. Use every opportunity and unexpected question to mention these.
Realize that sometimes what you say isn't as important as how you say it. Be confident, enthusiastic, and remember to smile often.
