Dublin is in a weird situation. Loads of immigrant here. I lived there couple years and worked in one of those big corps.

Salaries do go quite up a while but statistics on the corporate ladder are stacked firmly against immigrants, the higher you go the less chance you have to find non local people.

With soft career ceiling and continuous influx of people salaries are driven down. You can still make a fine living, but nothing compared to the colleagues on the other side of the ocean.

That's what I thought. I'm in Dublin too but not in google/fb/etc
