Heyy, it took them just a bit under 2 weeks to send me an invitation for the video interview after completing my SJT! Hope that helps. Also, the scheme I applied for was the finance one not the one I put previously, that was my mistake, so the interview invitations could have been sent sooner or later depending on your scheme.
For 2023, it seems like the finance application isn't up. But everything else is. Its still using the last year detail and saying register your interest.
