How does CVP SA & A1 Recruiting Work in London?

Hi all. I’m reapplying for SA roles next year and I go to a target in London. Really gunning for CVP and would love the opportunity to apply, just wondering if anyone has any experience/insight to how they recruit for entry level roles? A couple of my friends last year got invited to a networking event which I think is the pipeline to even be allowed to apply. I also know that they only recruit a select few unis (my university included) and I saw their job posting on my uni’s career page last year, but I’m sure that this wasn’t just a direct link to apply because my understanding is that you have to be invited to apply somehow. Any input appreciated.
