Understanding Passive vs Active Candidates

Active candidates

• Currently job hunting
• Easy to find through job boards
• Often apply to multiple positions
• May be less selective

Passive candidates

• Not actively looking for jobs
• Often the best talent
• Require more sophisticated sourcing
• More likely to be a good fit

Advanced Sourcing Strategies

1. X‑Ray search

X‑Ray search uses Google’s advanced operators to surface candidates across multiple platforms.

Example:

site:linkedin.com/in/ "Software Engineer" "Python" "Machine Learning" -intitle:"Software Engineer"

This finds LinkedIn profiles with specific skills but excludes those with “Software Engineer” in the title.

2. Social Media Sourcing

Platforms like Twitter, GitHub, and Stack Overflow can reveal highly engaged professionals.

GitHub Search:

language:python location:"San Francisco" followers:>100

Twitter Search:

"software engineer" "python" "machine learning" -job -hiring -looking

3. Conference and Event Sourcing

Find candidates who attend industry events and conferences.

Search Strategy:

"Conference Name" "Speaker" OR "Presenter" OR "Attendee" "Your Industry"

4. Company Alumni Networks

Target former employees of companies known for quality talent.

Example:

"Former Company Name" "Previous Company" "Ex-Company" "Your Target Role"
