Are there any reputed job hiring WhatsApp groups?

Hey folks! After much deliberation, I've quit cold turkey. The company I was working for was, for lack of a better term, toxic on multiple levels. There were some serious concerns of violation of labour rules and such. The sequence of transitioning is usually to have an offer in hand and then resign. However, given how much this job was draining me (had to travel from JP nagar to Whitefield everyday, spend 14 hours total), I figured I'd have to resign first and then scout for a job. So I am looking for any and all help in trying to land my next job. I was wondering if any of you were part of communities, on WhatsApp, LinkedIn or any other platforms, where you had visibility to job postings?
