Responsible recruiters and agencies will always vet their clients before agreeing to take on their job order. Some of the things you should look out for is a history of constant employee turnover, sexual harassment accusations, stories of discrimination, poor health and safety records, and lousy employee reviews on review sites such as glassdoor.com. If a client mentions they have burned through multiple recruitment firms, this is also another major red flag. Discuss with the interviewer your thoughts on ethical hiring and your process when it comes to onboarding new clients.

"The agency I currently work for is very selective on who they take on as a client. We have an online questionnaire, then a phone or in-person meeting. Whenever possible, I will make a site visit to see the environment in which my successful candidate would be working. I look for red flags such as a high amount of turnover, bad mojo in the office, any discriminatory language used in meetings, and more. If I would not place a friend in the role, I do not take on the job order."
