I seem to have a bit of a talent for the recruitment process. Never applied for a job and not got it . I'll tell you about some of my experiences and hopefully it will be useful for you.

My most recent job was a really well paid graduate job. I went to the interview with an unconventional combination of suit and trainers and was very casual. I think that by being a bit different combined with my super brief one page CV, it made them intrigued to know more and they would feel like they may be missing out on something if they don't hire me. That is a powerful thing when getting people to take action, the 'fear of loss' as it is known.

The job before that was a placement year. I was six and a half hours late for that interview. One of the questions they asked me was 'Give an example of a time when you have had to show determination'. I took the opportunity to explain what a long day I had had and all the obstacles I had had to overcome to get there, in a humourous way.

It is very important that you stand out.

I refuse to buy into the whole professional conduct game, it's so fake. I am just myself. I think that employers respond well to that. I imagine it is probably a breath of fresh air.

Be calm,
Be confident,
Be humble,

Don't be afraid to be yourself,
Don't be afraid to be different,

Don't feel like you are at their mercy, they are the one who are looking for an employee, it's them that needs you. After all, you are the best candidate and if they don't give you the job then they are loosing out and some other company will get you

If you want I can have a look at your CV and see if I can suggest some improvements for it? Two interviews in over 30 applications is not enough, I can almost guarantee that your CV can be improved. Either that or you are applying for the wrong jobs.
