Interview Dates / Decision Dates on Mature Student Applications?

[Jackass]

Hi, I've applied to 7 colleges for mature student courses:

UCD, Trinity, DCU, DIT, NCI, ITT & ITB

I was just wondering if anyone knows when interviews are held for some of these colleges (Trinity, DIT, NCI) and for the colleges who don't hold interviews but decide off admission exam / CAO application docs only ( UCD, ITT, ITB and DCU???) when are we notified of acceptence or not?

Thanks
