Sharing my experience:

28/4/22: Submitted CV at 1 pm and hiring manager reached out at 5 pm to schedule chit chat
12/5/22 : Chit Chat session
21/5/22 : Submitted docs
30/6/22: HR called to schedule TA/CBI
07/7/22 : TA/CBI
14/7/22 : Passed TA/CBI
15/8/22 : HR asked to fill up the application form online
19/8/22 : Received offer letter at the end of Friday night

I think 4 months is not really that long if you compare with some other people in this forum.
Another reason could be because I submitted my CV on Thursday, right before Hari Raya. Then, with all the raya celebrations, it got delayed even more.
All in all, worth the wait
