We recommend completing the questionnaire on a computer, and not on a mobile device. 

View the tutorial video prior to completing the assessment questionnaire. 

The job title field must be completed by selecting a job title from the dropdown menu options. This is explained from the 4:26 time mark of the video. If you do not enter the job title(s) correctly, your assessment outcome will be ineligible and you will need to resubmit the entire questionnaire again.
