I applied online. The process took a few weeks. There are a few computer-based tests initially before an invite to an online interview on Teams.
The interview lasted a full hour, and they ask a lot of questions which all align with the five competencies and values of Professional Development, Working with Others, Following Processes and Procedures, Influencing the Behaviours of Others, and Problem Solving.
I heard back within an hour that I had been successful. You then need to arrange a medical and fitness test which takes place in Polmont.
