The employer decides if the questions are open are hidden. In the main employers choose to hide the questions so just like in a real interview you get a small amount of time to prepare. This is set to 30 seconds but if you are ready to answer before then just click 'Start now'. Don't worry you get a chance to do a retake if you are not happy.
Typically you have 45s to 1 minute to answer the question. You don't need to use all this time, but you can't go past the time suggested. The employer decides how much time you have to answer.
If the questions are hidden you will see the interview questions one by one as you begin your interview.
The questions are always at the top of the screen.
Once you finish answering one question, the next one will appear on the top of the screen before you begin recording.
You will need to answer one question at a time. There is no option to skip a question and come back to it later.
You will be able to review each answer immediately after recording it, but you will not be able to go back at the end of your interview and review all of your answers.
Once you hit "Next", you'll be moving onto the next question, so double check that you're happy with your answer before you submit.
