Online application followed by tests.
Received an invitation to an assessment day. Given a presentation title and a week to send a copy of it.
Actual day consisted of an introduction, group exercise, presentation and finished with an interview. There was also lunch provided and a chance to speak with graduates working there who also provide a tour.
The group exercise required working through a problem and then giving a group presentation within the allocated time. The main difficulty is in speaking loud enough to be heard by the panel observing.
Overall it was a good experience and good way to learn about the company.
