We are sorry you felt you did not have a positive experience. All candidates are informed during the beginning of the process that because of the volume of candidates who complete the exercise, we are unable to provide individual feedback. Additionally, the exercise we request all applicants to complete prior to being interviewed serves as the individual's portfolio to demonstrate that he/she/they possess the required skills to fulfill the role. It is not free labor as it serves no other purpose than to assess your skillset. We wish you success with your search.
