Attended an assessment day where we learnt about the company, met the other applicants and had our interview. The process was excellent and well organised, which made me accept this offer over competition. The offer was made quickly as well.
We had a problem presented to us prior to the interview which we were to give a short response on, so we discussed my answers to that. This mostly focused on my presentation of the answers and not the answers. I was asked if I liked report writing, and about my experience from my summer job. Then we discussed hobbies and interests.
Be sincere and confident, with an open mind to learn as much as you can.
