I am always nervous about interviews, but you have no choice. I do the best I can and prepare for it. I always eat a good meal, where some fresh clothes, and just make sure I had a nice sleep the day before, I look to arrive there atleast 30 mins before the scheduled time.
No, I was just saying the level. I wasn't be literal, I was saying he/she isn't different or more powerful than me just because of their job or position 😛
