It was very quick, appointment was at 10 am on the 8th Jan, in total we were there probably 1hr and 10 min max.
To be honest quite straight forward, but the personal taking our documents on the first stage was a bit strange, asked me for proof that I don't need a sponsor or jiob offer, which didn't apply to me.
Then the next stage was super simple, biometrics, confirm names, and that was it.
I was surprised no other questions were asked.
