The interview will be at EI head office at the airport and there are a few hotels immediately adjacent to it (Clarion and Great Southern) however they are airport hotels. If you are successful at the interview they will send you for a medical in a town called Malahide not far from the airport (and subsequently my home town) which is really nice and pretty by the seaside and with a good hotel there called the Grand. You can catch a bus to the airport for about €2. You can also get the train from Malahide into the city center in about 20 minutes so its a nice little place to base yourself. And if your feeling really adventurous, just further along the coast road from the Grand (About 3 minutes in a taxi) is a dodgy nightclub called tomangoes where all the aer lingus heads hang out cos it gives an airline discount!!
