There are lots of opportunities for personal development during the traineeship. For example: on and off the job coaching by your mentor, a dedicated business coach and an external coach. There are internal- and external training sessions to give you and your fellow trainees more information to be able to discover what motivates you and to specify your development goals.
Examples of courses are: Insights Discovery, Time Management, Finance for non-Financials, safety courses, specific dredging, offshore or infra related courses, depending on your specialization. These are just examples as there are a lot more courses to sink your teeth into.
