For an assessment-based platform I would expect to see more question types such as:
True/False: Select whether a statement is true or false.
Fill in the Blank: Type the correct word or phrase to complete a sentence.
Matching: Match items from one list to corresponding items on another list.
Rating Scale: Select a point on a scale to indicate your level of agreement or satisfaction.
Numerical Response: Enter a numerical answer.
Audio questions: Provide an audio based question
Outside of dev/engineer based questions the scope of question types is limited for academic style tests. Are you looking to expand your offering in the near future?
