I applied online. The process took 2+ months. I interviewed at Bookassist (Dublin, Dublin) in Apr 2017
Interview
I have applied on the website, also sent an e-mail to the hiring manager. After 10 weeks I had 7 follow-ups via e-mail and 3 calls to the office.
I finally received an e-mail saying the position is filled.
I really haven't encountered a more difficult company to get a hold of.
