To those asking for the timeline of the offer - I did my AC in Dec, did panel interview early Jan and got offered around 2nd week of jan. HR gave a call and followed up with a email afterwards.
To those that haven’t called up yet, maybe that is because your panel interview is conducted slightly lately so don’t lose hope yet! Also, I know of those that have received offer but are rejecting so they might call up more people.
I think might be possible to wait till end of this month for the offer. Take care
