Good Sharing. Thanks =)
I am a fresh graduate few months back this year. I went for a job for a month, and had made a decision to move on to another job that has bright future. My advice,
during the interview
1) when asked for expected salary range, give a reasonable number that can actually cover your traveling (fuel plus tol) and food cost ( in case the company do not provide travelling allowance etc.)
2)check whether there is insurance coverage for you - if u need it
3) working days and hours (will it work for you?)
4) Usually interviewer would explain to you about your job scope. If not, you can ask about it, at the end of the interview,when you are given chance to ask.
After the interview
1) watch for the contract paper which you might be asked to signed. Read the T&C first! - I didnt get mines anyhow
Some employers might not give, as they would set a period before they confirm you

During work
1) If unsure, stop it there and ask somebody who knows better than you, just to avoid some potential disastrous mistake.
2)Ask questions, make yourself a useful busybody but not to the extent of disrupting people busy working.
3) if you are dealing with documents, familiarise yourself to the types of documents and pattern of filing, etc. Have a look around the working place, to see what they actually have.
4) Maintain a cheerful attitude, be alert , have some good eye contact when somebody is talking to you
5) As you made a mistake, you to prepare yourself for the consequences, and if asked to justify, be ready to give a concrete reason for committing the mistake. During the 1st week, mistakes may be excusable, but it should be avoided later on. Don't repeat same mistake twice.
The office that I worked in previously pushed me general works and and also for clinical operations. Things were tough as i was expected to perform both, but weighing more to general side. Basically, stamping, photocopying, cutting pappers... yikess..The manager was supposed to hire a second general clerk, and i clearly didn't apply for a clerk position. However, another freshie who joined work much later than me, has the pleasure to work within her work zone. Unfortunately to say, I faced unfair treatment which I regret till now.
Plus, the handing of salary was much delayed, but the knowledge I gained was valuable on the other hand.
It can be stressful for some of you. Freshie life is painful i know
However, this was my bit of experience i gathered in my previous office. Hope it helps.
But now, a better job is there for me, with the fringe benefits.
