I haven't seen this talked about in the comments so thought I would mention it: depending on where you're from and where you're planning to go, you could try a Working Holiday Visa.
Not all countries are part of this program and the ones that do all have their own requirements (usually there is an age limit of < 30 years but this can vary). So have a look if the country you're from supports the program and if so which countries you could go to.
The big advantage if you can get it is you get a one year visa without the need of having a job or anything before going. You can then just fly over to the country, find a place to stay and search for a job while there.
As others have said I would recommend Ireland. I spent 3 years working in Dublin after I graduated and it was the best time of my life! Irish people are very welcoming and you will find a job fairly easily (although your first one could be a tech support / very junior role). Biggest issue of Dublin is the housing market is a disaster at the moment so don't expect to get your own 2 bedrooms apartment. Although that's mostly a Dublin issue, but that's where you would get the most jobs in the country.
There are other countries too where you could find english speaking jobs (Netherlands, Germany...) but you would still probably need some basics in the local language for day-to-day life. Ireland doesn't have that issue obviously.
