My personal experience was different from most, as I worked on my honours project with the company and then landed a graduate role through that after work experience. The current hiring process seems full on and I feel that it will be tailored every year to adjust the process to target the type of graduates that they are looking for. However, I would say not to judge the company on their hiring process, although this part is full on, the company is a relaxed and motivating environment to work in.
To land the substations engineer role from the graduate role, some of the questions were: - talk about a safety incident you have witnessed; - talk about a time you have worked in a group situation; - talk about a time when you had to lead; - technical question associated with the role: how would you manage TasNetworks assets in the regulatory world that we are in? To be honest, I cannot remember the rest.
Prepare, prepare, prepare. It is easy to tell apart the candidates that have prepared and those that haven't. Be innovative with any presentations you are assigned - think outside the box. Also be genuine - the process is designed to see if you fit in with the culture of the company and vice versa - if its not a good fit, you are unlikely to be happy coming to work each day.
