If I have any advices, that would be be confident and be true to yourself.
On the commercial side, most interviews are behavioral, interviewers askign general questions and observe and analyze your answer, and most importantly, the way you answer it. Most questions are like these:
- What is your strength and weakness and what have you done to improve them?
- How do you deal with conflicts at work and what is the outcome?
- What value you appreciate the most from your supervisor?
