They want you to complete a task and send a video. The position is always open. Looks like they are just harvesting candidates’s data. I don’t think they are a good place to work.

Make you do extensive skills tests before any sort of communication. During the application process they use language that makes you feel like you're going to miss out on an interview opportunity (which likely won't happen anyway) if you don't complete every OPTIONAL step. For example, when you submit the form with your details they mention that people who complete what's essentially free research for them will be prioritised. Then you continue on to do what could be considered ridiculously lengthy tests for them. They also require a 5 minute video introduction to be sent to them too, so you feel judged before meeting a single person. It's invasive, and who knows if biases will be used against you for silly things like your appearance? They say in the confirmation emails that it will take up to 30 days to review your tests but when you check their tracking system, it gives the actual amount of days which is 30-60.
