I have been working at AIA Worldwide full-time (More than a year)
Great culture, very interested in their employees lives outside of work as well as inside - the people are fun, and the atmosphere is fast paced but thoroughly enjoyable. Definitely a place to gain huge experience + growth within the digital marketing world
Long hours during grad season however great fun to see the happy client faces upon delivery - don't let this sway you as this industry is not for wimps - if you cant handle the heat, then stay out of the kitchen.
I applied online. The process took 3 weeks. I interviewed at AIA Worldwide (London, England (UK)).
The interview process was very straight forward and clear. They allowed me to get across my skills and knowledge in a relaxed atmosphere, asked good questions and made me feel welcome.
