never discuss salary openly : get over the line first, the salary can come later with the exception if they -do- ask you for a salary, give them a range. Explain why you think you are worth that sort of money too but set the low end above your expectation, you can always negotiate down but always keep it reasonable.
the usual question will be "what do you expect from this role?" never go "oh about $28k a year!" - go with "opportunities to train and learn new disciplines, the ability to build a network etc"
Where do you expect to be in 5 years? "i want to have establish myself in the firm as a key resource - it's my belief that to truly understand the operation of a firm you must see it from as many angles as possible. etc etc"
Be honest on the "what is your biggest weakness?" - "i'm a perfectionist" is a grade A duff argument. Instead go with "well, i have previously had issues with <a> but i have since taken the following <b> actions to resolve this. As a result - i've noticed that my performance in this area has become vastly improved. However, it's something i am mindful of and i take time to ensure that i'm developing skills in this area"
with one interviewer - try to maintain a friendly eye contact.
with two+ - do the "shallow W" movement so as you are talking to people you are literally talking to everyone. Just be calm with the headmovement or you'll look crazy.
"Tell me about a time you failed" - obviously - if you burnt down the HQ of your last firm maybe not a great idea to tell them about that without a lawyer present, but you can be vaguely honest here. Again - the key is to ensure you learned something you didn't know before. Were the safety rules that were followed? did you feel you didn't push back enough? etc - just explain what happened, what you did, what you thought of that action, why you thought it went badly, how you would improve it... etc - key is to have taken something away from a failed project, no matter what it is.
Be aware what you are doing with your hands - don't keep them on your lap, don't wave them in the air like you just dont care. The cross fingered fold is a good look, and look attentive when the interviewers are speaking. The odd nod of the head in agreement helps when they are discussing items about the job or the role.
if asked about Hobbies : look - just don't mention vidya. I'm serious. I interviewed here in Japan with people i knew were into vidya but it's just best left alone. Go with one of your other hobbies. Whether we like it or not, there's a stigma - even in Japan. Go with Music/exercise etc.
Always have at least one question : what do you see as the major challenges for the firm in the next 5 years? What do you see as the contributions i can bring to the firm to help resolve those issues?
and the ultimate "i was reading on your website that you are looking into <thing> , can you explain a little more about this to me please? etc etc.
Infact - always read the corporate website of wherever company you are approaching - and check the news to see if they are involved in -anything- in the past few months. Certainly you should try to be familiar with the "Mission Statement" of the company at the very least. Because the first thing you will likely be asked "what do you know about us?" - if you can throw back their corporate profile to them then they know you have the initiative to go look before the meeting.
It's all good though - there's no real right or wrong way to do an interview (bit of a lie....) but the core thing is to be yourself. Relax. In the end you are selling your time to them, not them buying you. So you need to keep that in mind. Some Jobs just won't be for you - and you just have to say no. This isn't a one way street, it's a conversation. You have something they want, they have something you want. Treat it that way. I'm not saying "HAGGLE!!!" i'm just saying relax, a lot of candidates tend to be so worked up and that's not what an interview is.
And most of all - Good luck!
oh and in all cases have EXAMPLES. The usual follow up is "explain to me how you resolved this issue?"
