there is no right or wrong in an interview, or how the interview
should be reviewed because differnt interviewer has different
expectation. only think is very basic things have to observe. wear
properly don't be late and so on.
True and false.
Having attended many interviews the past month, I'd say that
employers look for qualities that befit the job position - and that
range from personality, experience and technical and soft skills.
Obviously, an employer wouldn't hire an introvert to do sales or a
business graduate to do software engineering.
It'd be good to know what kind of personality would suit the
position and you can 'play down' to that personality type. No one
is 100% honest in an interview... if you're an introvert, say
you're perfectionist; if you're careless, say you look at the big
picture and if you're sociable, then you're a teamplayer
Your flaws should
be presented the way it appears to be virtues which aren't too
positive.
The first few interviews I had, I was being too
frank and it killed a lot of opportunities. Always
remember to exude enthusiasm, confidence and maturity - just think
of it as trying to sell yourself. I find building a rapport with
the interviewers a priority, the first 30 seconds can and will
determine how the interview will go.
Things like being dressed properly, arriving at least 15 minutes
earlier, be mindful of your body language... Sit straight with your
back firmly against the back rest of the chair, don't touch your
face shouldn't even need to be mentioned. I mean.. hey...
that's the most basic of etiquette, if you don't have it... You
really don't deserve the job 
TS, can try sending an email to thank the interviewers at the
end of it too. That will get you some brownie points at least.
