Just to update, today my employer and I received the calls almost same time. Nothing difficult very simple questions, where I work and who I report to, and wether I am related to the employer, which I am not.
Only thing is I had to repeat my marriage dates few times, I was saying something else they were repeating something else. In the end I humbly request them to repeat the dates, so I didn't want to get them wrong.
Finally they said they will pass my details to decision making team, which might contact me with email.
I was under the impression its the actual case work which makes the call ? But it suggest there different teams working on the application ?
