I have found a Whatsapp Job Seekers group links. There a good thing is they have shown field wise whatsapp groups like Computer Engineering Jobs, Mechanical Engineering Jobs, Accountant Jobs, Administrative Jobs, and so on.
There is also some freelance work groups, it will be easy if you open it in the mobile otherwise it will ask to join your mobile whatsapp with the desktop, so in this case if you are on your own desktop then it will be ok otherwise I will recommend do not connect your whatsapp with this link.
