It is extremely important that people who have epilepsy or other photo-sensitive conditions are not exposed to significant flickering or flashing. It is possible that video clips, multimedia presentations or computer tasks include flickering or flashing that would be dangerous for these candidates to see. You should ensure any computer tasks and videos (including those on your website) are free from these effects and also any videos or presentations they may see when coming in for an interview or meeting.
You can check whether a video or animation is dangerous using the Trace Center flicker test tool.
