Interviews in most of the working world are likely to be pretty arbitrary, if you're not comfortable with the sort of thing, maybe a combination of forthrightness and not-volunteering-too-much is a good baseline. (People with better employment histories than I might quibble about the honesty bit, admittedly.) Be in a strong space.
On the honesty thing, well, if you're not confident about interview skills, it can sometimes be that that combination of honesty+lack of confidence leads people to end up trying to *explain themselves* while to a lot of the business-school mindset, they're going to see that as 'Everyone's hiding something, so this all must be just a *big smokescreen.*'
Fact is, in a lot of places (Maybe not so much 'the theater,' but it you're talking about ushering at the cinema, maybe indeed,) chances are you're meeting a middle manager, and Gods know what crackpot 'How To Interview Employees' business tapes and seminars they've been ingesting to begin with, so what you have is often some kind of dance between *those* schemes and 'How To Interview For Jobs' schemes, so I say just whatever makes you a *presence* is more likely to make everyone happier in the long run.
Thing is, that kind of concern tends to be pretty secondary in this day and age and a lot of middle-management types really can be cynical bastiches. Usually, they don't want to *see* themselves that way, though, so pay attention to *them,* and consider that people usually prefer simple narratives to elaborate explanations and too much information (Which latter point, as you can well see, is hardly a strong point of my own.
)
Introspective people are commonly at an employment disadvantage amid all this, ...if you wonder why so many 'successful' people just seem so thick about some things, perhaps this is why.
Some even just say "Lie. It's expected." Apart from that there's obviously too few *words* in that strategy for me, that's something I'm generally not willing to do for a purpose like that. (A clever person might note the qualifiers: my code of honesty doesn't categorically-extend to enabling *abuse of that honesty,* let's say. Frankly, a lot of those 'strategies' being sold and played against each other are *just that,* really, trying to wring out of convoluted and sometimes-conflicting interests, strategies, and compromises, what straight-up honesty and an environment of fair dealings could provide. The systems are obviously generally-unkind to idealists, though, of course. )
For simpler, don't think of it as an 'examination.' Or all that 'deception, fact finding, interrogation' sort of model. Think of it as a performance, portraying yourself as an employee, there.
And don't act like anybody you aren't prepared to be, there.
