Below in my experience are a list of the 10 most-difficult-to-answer questions during an interview session

1. What are your salary requirements? or How much do you think we should pay you?
2. Introduce yourself to Us
3. Why do you want to work for this company?
4. Why did you leave your former job? or Why do you want another job? (this is even more difficult if you were sacked
in your former job)
5. How do you get along with your colleagues?
6. Have you been interviewing for other jobs?
7. Where do you see yourself 5 years from now?
8. What do you Know about this company? (even more difficult when you have not done any prior research
on the company)
9. What is your code of conduct?

10. We are humans as such not perfect. So What are your areas of weaknesses?
