BT Degree Apprenticeship Scheme 2021Watch
Quick guides to apprenticeships
If by BT you mean British Telecom, then most, if not all people that posted in the BT graduate scheme thread passed their video assessments. But everyone is now waiting for either a confirmation of getting an assessment centre or a rejection. As an educated guess, your scheme will probably be following a similar timeline.
It might be wise to do it just for the experience - it will help for roles you actually do want to apply for and you never know, maybe at the end of summer this will be the only role you get accepted for and you may have changed your mind.
