Different types of selection criteria are meant to provide the employer with information that allow them to make an assessment of your (potential) suitability for the role they offer.
Student Experience and Career Development
Example: "Outline your relevant postgraduate qualifications"
Although the employer will have the core of this information by reading your resume, you may be able to provide further details on how your qualifications are relevant to the role, or how your further training makes you stand out as a good choice for the role.
Example: "Why do you want to work for organisation X?"
The employer is going to invest time, energy and money into you if you win the job, and needs to know they're going to get a return on their investment. The employer needs to know that you are interested, and even have passion for the industry, organisation and role so that he or she is assured that you will put in your best efforts in your professional activities.
'Excellent communications skills - interpersonal and written'
'Proven teamwork/leadership skills'
'Conceptual and analytical skills" "Flexibility, adaptability and initiative'
These questions illustrate behaviourally-based (or competency-based) selection criteria. These types of questions are the most common form of Selection Criteria. They are based on the premise that past behaviour predicts future behaviour. This means you have to use an explicit and specific example that best illustrates your skill development.
