To have your data deleted, please contact the company for which you recorded the interview. This can be done by letting your recruiter know (contact details can be found in your invitation mail) that you would like to have your data removed.
Another possibility to get your data deleted is on the company's career page. Visit the career page and scroll all the way down to the bottom. There you will find a link called 'request to view, download and delete your personal information'.
Finally, click on the link and type in your email address with which you have applied as shown in the picture below.
We hope to see you again soon! 😊
