[General] As communicated

[suniljain]

As communicated, we confirm your interview tomorrow at 11 AM in our Delhi office.


May I use "in" above as highlighted in red color or I should use "at".

 

[bhaisahab]

I'd use "at" but I'd accept "in".

 

[tedmc]

Is it common or natural to use "as communicated"?

 

[MikeNewYork]

It is fine.

 

[Barb_D]

And I would have said it was completely unnecessary.
This confirms your interview...
