Vantaggi
Great training system and the people who work there are great. Everyone speaks your moral up and great diversity of people who work in the office. I had this job part-time whilst at uni and it was great as you worked the same hours every week so you could plan your schedule around it, there was a healthy amount of pressure to the job but not too much to effect my university studies which was great. The pay is great for a student and very easy to refer a friends to the same job too.
Svantaggi
After leaving Uni the pay wasn't as much as I wanted to earn, however there are ways to work your way up in the company which increases the pay to a decent amount. However its not the avenue I want to go into but that's just a personal preference :)
