When and where you complete your interview is up to you, however, we can offer some rules and guidelines.
Your invitation email will specify a deadline for your interview. This deadline is the date and time by which you must have completed all responses for your interview, otherwise it will be considered an expired interview, and will no longer be accessible to you and you will need to request an extension from your recruiter.
Apart from this deadline, you can start and complete your interview at any time after receiving your invitation. When you select to start your interview, your browser will go through a brief check and you will be able to record an answer to a practice question, before commencing the actual interview.
