The following hints and tips may appear obvious but quite often you can miss something when applying online:
Don’t leave it too late to apply.
Consider your application carefully – you will only get one chance to make a first impression.
Check that you are applying for the correct job!
Review your Resume or CV to check whether it needs updating or a change of emphasis for the current application.
Ensure that it emphasises the key skills and experience that you have which match those specified in the job advert.
Ensure that it is clear from your Resume or CV what YOU have actually achieved or done, not just what the company or the department you worked in was meant to have done!
Where possible send a covering email or letter highlighting your interest in the job and company and your suitability for it.
Look carefully at the job advert and highlight in your covering email or letter where your skills and experiences match those requested.
Find out as much information as you can about the company (look at their web site) and its vision/values etc. Check to see if there is anything that matches with your skills and experience.
If you don’t have the requested experience or qualifications, but you believe that you could still do the job, emphasise the reasons why.
Check that any email or letter attached relates only to that application and not to a previous application!. This is especially important when cutting and pasting! Check that the job reference is correct and it has the correct date on it!
Finally, don't send off your Resume or CV without reviewing it again.
