I just received this card never having been a St G customer before, and I was 'intrigued' with the process, having had cards with almost every other major bank + AMEX. I don't know if it's a reflection on process changes since the RC, but I suspect not. Whilst my circumstances probably aren't straight-forward, I note with interest the other posters who report just how laborious the process was and that was my experience too. Conditionally approved instantly, but then multiple requests for 'more information'.
There were also 'little things' like having to go to the branch to get the cards, and not being able to apply online for additional card holders.
I can't quite work-out if they're just better at due diligence than their competitors, or just a bit less tech-saavy - I'll give them the benefit of the doubt...!
