The hiring process was very easy for the graduate programme. Following my application, I was invited to attend an assessment day at NZX. This was a great opportunity to get a feel for the organisation, and meet the employees and other applicants.
Most of the questions were situational based "can you tell us about a time when...", this required me to think on the spot about specific stories that have helped me grow and learn. Also questions such as why I was interested in the role, in my sector, what I am most proud of etc, which were good for me to express my personal thoughts.
Put your best self forward in your application, study the NZX values and think of examples of times you displayed those values. At the interview day, don't worry so much about being the perfect student candidate, get to know everyone and make an effort to talk to the senior management to make a good impression.
