I applied in late September and didn't get contacted until mid-November. HR communicated mainly in emails. I got interviewed online 2 weeks after the invitation. It was pretty annoying the mails from Maynooth people go to spam all the time. If you apply for a job there, remember to check your spam. 4 people on the interview panel for an executive job, 3 people asked more than 10 questions within 30 minutes in total, it was indeed a bit tense. The candidate really had to be prepared.
