I applied online through a job search website. I'd received an email a couple of weeks later to attend an interview in Craigavon where their HQ is. Don't know if I have the job yet but I asked and they said it should be the following week from the interview. I've just come home and updated this while the questions are fresh. The lady and gentleman who interviewed me were very accommodating and helped me if I needed a bit more clarity on the questions.
