Interview is usually a group interview. Don't expect anything too tough as they take on anyone for the summer season.
Do you know if it is a check-in position? If so the training is a few days on the computer system they use (CODECO), boarding proceedures, some customer service training, manual handling, health and safety, security, possibly some emgercency prodeedures and a few videos. Once complete you will usually shadow current employees to see how the job is done before going live.
Contracts are usually 25hours per week with plenty of overtime. Start times are all over the shop with the earliest start being around 3am.
Servisair as a company are one of the lowest paying handling agents around. Or they were when I worked for them. There are some good staff and some bad staff just as you would find in any job.
Best of luck.
