Most of the whatsapp group are made up of in process candidates and rarely any expert. But good part is all combined can share their experience asap and this way seeking answers are fast. I have created a group where we share and help each other but none is expert. If you want I can add you up DM or post you phone number with country code.
P.S. Best advice you can get is from this forum. There are so many selfless helpful expert members who check here regularly and try to help in their best capacity.
