Just to share my current timeline:

End Jan 2024- Contacted by hiring manager/hiring team for an informal interview
Early Feb 2024- went for the informal interview
Early Feb 2024 (before CNY)- did a writing test
Mid Feb 2024 (after CNY)- meet with another hiring manager (same department tho) for an informal interview.
Early March 2024- HR contacted me to submit G50. No verbal offer, but hiring manager said formal offer will be made once cleared the G50.
