Start with your current occupation, if you're in work, and then list all the relevant work or work experience you've gained. Go into detail to explain your duties, what skills you picked up and why those skills would prove relevant in the job you're applying for. Okay, you're making progress. Your education details should come next. Don't be vague about your important results but don't list every exam you passed since primary school either.
Interests is the next main section.
If your hobby is mountain climbing and you've scaled K2, cool. If your hobby is eating kebabs, not so cool. Don't go into too much detail here but use the opportunity to explain any extra qualifications you might have. Finally, include names and addresses for two referees. You'll probably be found out or shown up at the interview stage.
