at job going away
don't know what 'the done thing' is there - you're outside the UK, aren't you?
in the UK, age discrimination is (in theory at least) now as illegal as sex / race discrimination (although there's employers out there who haven't really grasped the latter - they have only been in law for 50 or so years now) so you don't put your date of birth / age on things.
Also, a CV (resume?) that goes back (say) 10 years and just summarises previous jobs as a single paragraph, and that lists qualifications without giving the dates you got them, and so on is sometimes recommended.
I tend to vary mine depending on circumstances - sometimes I want to include something I did 20 years ago because it's more relevant to the job I'm going for than what I've done recently, sometimes I'll go in to more detail about something that was only a temporary job, but is relevant. (In other words, have a master CV and edit it for each application depending on what bit of your skills / experience are the best selling point for this job.)
But it may be completely different where you are.
It's certainly not standard in the UK to include a photograph on your CV unless perhaps you're an actor or model or something like that.
I remember a thread (can't remember if it was on urban or somewhere else) where someone had sent a CV to an agency - they said it was the wrong format and to do it like this. He did, then sent it to another agency who said it was the wrong format. Aargh.
What are you like with computers / IT stuff? Do you have any recent qualifications (even if it's relatively basic / intermediate level on the MS Office basics?) - some employers assume that anyone over 40 doesn't know how to use a computer and / or can't learn anything new, although if you're close to finishing a degree course, that may blast the latter assumption in to orbit for them.
Again, no idea how they do it there, but an increasing number of employers now do 'competency based' interviews - rather than a question like 'what would you do if X happened?', it's 'give me an example of a time you did X' - X can either be a specific technical skill, or something fuzzier like 'provided excellent customer service' - these take a bit of getting used to, and like most things can be done well or badly. I've had 'competency' interviews that have been more like a natter down the pub about jobs i've done in the past, with someone who understands the job. I've also had some where it's been some nurk from HR who knows nothing about the job, and is just scoring you on whether you come out with all the buzzwords on their check-list. If you've not met it, it's worth researching 'STAR' (situation - task - action - result), and also remembering that the organisation / team objectives are the situation, the task / action are about you and whatever your role is / was.
In public sector here, the application form can be competency based as well, asking you to explain how you meet the skills / experience etc they are asking for in the job description / person specification. Don't know if that's a thing where you are.
Hope all goes well.
