or find its employees. Of course, similar technique can be used for other purposes.
1. Find an ex-employee of a company (change McKinsey below for your target company name; also for every example vary the number of asterisks for more results):
"I worked * McKinsey" (or "I worked * * McKinsey" etc.; vary the number of * for all of the following strings as well)
"I used to * McKinsey"
"I * former McKinsey"
(you get the idea)
2. Find current or past employees:
"I am * McKinsey"
"I * work OR working * McKinsey"
3. Find emails:
"email * McKinsey.com"
"mailto * McKinsey.com"
4. Find competitors:
"competitors * McKinsey"
