If a candidate tries to exit during an interview we ask them if they are sure they want to exit as if they do they will not be able to complete the interview. If they answer yes and they exit, their interview is not complete and will be marked so for the employer. This will appear in their profile and employers can choose to remove you from the job matching.
If the candidate decides “no”, then the interview continues on and completes to the end.
Remember - If you exit an interview without completing it, you will be unable to re-start it.
