Interview
You have to sit through a 30 minute presentation, they introduce the company and what an average day would look like. You are then divided into teams and given scenarios, to which you have to intellectually provide solutions. Later, you're asked to give a 1 minute presentation on any topic chosen by your fellow colleagues.
