A colleague is putting his resume together for the first time in several years. “I've been at the same desk, working for the same boss, on the same projects for the last three years. But my company has changed names at least four times in that time. What do I say?”
Here's the way I like to see the company names on a resume:
month/year, CurrentCompanyName, city, state. (Previously known as CurrentCompany-1, CurrentCompany-2, CurrentCompany-3) YourJobTitle.
Unless your responsibilities have changed, you've had one job.
Hiring managers: don't ding candidates on what looks like job changes. It isn't the candidate's fault the company management sold/bought the company.
