Just received my GC today. We are very lucky; our interview got waived perhaps due to the corona virus pandemic.
Here's a timeline for your reference.

-----------------------------------------------------
It took 2 years to get this done.
And we thought there would be interview; for individual applicant (who is single, without spouse), we heard people got interview waived. But I have my wife in our I-485, so we didn't expected our interview to be waived.
So I think we are really lucky.
Good luck to everyone here!
