I have my first job interview अगला week. Any tips? Also, the interview is at noon and I have class before that so it's not very practical to dress up. So, do आप think it would be ok to wear a nice sweater & black jeans with black boots?

Doesn't matter what आप are doing before, get suited up. आप have to dress to impress.

Be prepared to answer सवालों about time management, and how आप organise priorities, as well as how आप get on with people.

Be relaxed, prepare your जवाब ahead of time.

I've been to dozens of job interviews and what above said, dress to impress. First impressions are paramount.

If you're worried choose a suit, get it cleaned, laundered and then hang it up on a कोट hanger, wrapped in a large plastic bag so it doesn't crease and keep it in your locker. That way आप can change in less then 3 मिनटों and be on your way. Make sure your shoes are shiny and brush your hair. If आप have no time to clean your teeth, suck mints.

Prepare your जवाब before hand, like above said. Imagain what सवालों they will ask आप and write down your answers. Practise in a mirror, with friends, your parents, your tutors until आप can rely on eye contact to get आप through.
आप CV should include any other jobs आप have done, references from your employers, anything आप do out of school time आप find interesting, what grades आप have/grades आप are predicted.
If आप haven't had a job yet, ask your tutors if they will write a short note on how they find आप in class.
And the best tip i was ever given. If आप do not understand a सवाल the employer asks, या wish for और time to think about your answer say ' could आप please repeat the question.'

Just remain calm and be as honest but positive as आप can.

For example,i told my current employer though i had expereince in waitressing it was not as high class as the establishment they were in, and that instead of telling me what to do (like how to carry 7 plates instead of 3) they would have to दिखाना me as i was a visiual learner. That will give your employer the confidence that आप know what आप need to learn.

I was employed in September 2010, we are now in Janurary 2011, and i am already an under-manager. To say i started as a waitress, that isn't so bad.
But आप must दिखाना आप can work hard and take things in.

6 If आप have to shake hands make it a firm hand shake not a सलाद, सलाद पत्ता leaf one
