A job interview is a performance.
Rehearse, rehearse, rehearse.
Know your lines.
Smile, be confident, shake hands firmly.
You need to be the best actor you can possibly be, you're going for an Oscar.
Look immaculately professional.
Do not under any circumstances be late.
Whilst these days the employer has their pick of who they hire, try to think of it as simply a conversation, a mutual exchange. You want to know as much about them as possible, they want to know as much about you as possible to see if you are the right fit.
Research the company like crazy. Magnolia might have been taking the mic but he has alluded to an important factor - there are good questions and bad questions to ask. I would say don't be afraid to be hands on, take a notepad and pen with you if necc, jot down questions you want to ask at the conclusion of the process as you go on. Appear to be sharp, and on the ball. If in doubt, ask about pensions, or something else run-of-the-mill business like. There are ways of asking the question too, you need to be polite, courteous, broach the subjects instead of asking outwright.
And you need to be the right fit. Like it or not, workplaces are social and YOU WILL NEED TO FIT IN, employers will be looking at this.
With this in mind - there is absolutely nothing to worry or get nervous about. It is THE MOST procedural thing ever, yet so many people shoot themselves in the foot by stressing themselves out beforehand, not getting a good nights sleep, getting stuck in traffic, etc.
You might as well treat it as an actual job interview, they're not investing in someone out of the goodness of their heart - they want return. I would say act as if you know exactly what job you want to do for them by the end of this scholarship and make out that you can basically already do it standing on your head (within reason of course, do not stray from acting with honesty and integrity).
Surprisingly, employers like to know really basic things about you too. Are you in good health? Do you have any kids or dependants? Are you single? Willing to relocate? How reliable are you? Strength and weaknesses? What are your extra curricular activities, what are you passionate about? Other achievements? They don't want someone who doesn't pursue some sort of interest that gets them out of the house / comfort zone to socialize. They want individuals with high levels of self-esteem and confidence. (Note:- not arrogance or passive-agressive assertiveness) Etc etc.
You have nothing to lose and everything to gain.
