Competency-based questions are often used in online systems - such as a series of scenarios in which you have to explain what you would do if faced with a similar situation. They tend to look for your motivation and ability to do the job and there are usually questions about the company’s current affairs, so make sure you have done your research before starting. Give yourself time to compose your answers beforehand, in a Word document for example, and then you can check them over before submitting them. There is not usually a time limit for online applications.
