Candidate Sourcing: 109 Slack Groups to Find New Hires

Mile Zivkovic Mile Zivkovic Last Updated:

Slack has become the go-to tool for work communication, boasting over 8 million daily active users. Over time, Slack became a meeting point for professionals to talk outside of their work, spawning several high calibre communities with vetted professionals. This makes Slack communities a powerful yet untapped candidate sourcing channel.

Candidate sourcing from Slack – dos and don’ts

If you think getting applicants’ interest is as simple as blasting a message to an entire channel and expecting results, you’re in for a surprise. Rules differ from one Slack community to another, but there are some general guidelines for sourcing from Slack.

1. Don’t message anyone directly

Chances are, the community rules forbid you from doing so, and potential candidates might see you as pushy and this can hurt your employer brand.

2. Don’t tag @channel or @here

Seeing how many Slack communities are international, you’ll send a notification to a large group of people across different time zones and continents – and many of them will not appreciate it.

3. Post in relevant channels only

If the community has a channel such as #jobs or #careers, that would be a great place to start. Snoop around and find the best channel for sourcing and attracting applicants.

4. Be responsive

Seeing how many Slack communities there are, it’s difficult to stay on top of comments and replies. If applicants reply to your messages, follow up promptly, be responsive and helpful and you’ll build your employer brand, as well as attract great people to apply for your open positions.
