Im in Ireland too and I completely agree with you.
Alot of it comes down to nepotism, it really is all about who you know. Also employers just arent willing to train people in anymore, nearly every job requires 2+ years experience.
Almost everyone ive known who got their first job did so through their parents or a family member or friend getting them the job through either owning a business or being friends with a manager - through this they built up the experience they needed to get another job somewhere else.
If you dont have this support starting out, it can be a downward spiral as no one will give you a chance without experience, cant get experience unless someones willing to give it to you, its a viscous cycle.
Education means nothing anymore as most people have atleast a level 8 qualification and even those with degrees and masters find it tough to get work unless they have connections. I recently finished a sub position in a school, the principal had employed his wife, niece, cousin, friends, friends children and even his old babysitter. Majority of the permanent staff were from the same town as the principal.
I know teachers and people with PHD's doing CE schemes just because they dont know the right people.
Ireland is such an expensive country that not working means youre very limited in what you can do to improve your circumstances, just learning how to drive and getting a car on the road costs over 10,000 and thats just for the first year.
Public transport costs a bomb and is very unreliable, this limits people in applying for work outside their home town or city as the travel expenses are often too high and buses and trains regularly show up late or not at all, I had to leave a job the far side of Dublin last year because I couldn't deal with the stress every morning of late buses and constantly being late for work even though I was up at 6 to be in work for 9 then waiting around for two hours for the bus home because the bus didnt show up at the time it was supposed to and not getting home til 9 at night even though id finished work at 5.30.
They just dont make it easy for people to get on their feet in this country, unless youve got a financially supportive family that can fund you through college, get you a car and insurance and help you get a job, its extremely hard to get anywhere because theres no supports or help at all and it feels like everything is set up for people with money and connections, the other option is to live off the dole and get a free house, theres no inbetween.
Keep trying, have your cv looked over by a guidance counselor and maybe invest in some interview coaching if you can.
