Q. I've been thinking about hiring somebody. My one concern is that their resume shows a lot of job jumping. Is that something that I should really be concerned about?
A. There's no one right answer to a question like that. The only possible answer is "it depends." You're seeing a pattern in this person's history. As the stock market people are fond of saying, past performance is not an indication of future performance. Still, patterns tend to repeat themselves.
We assume that you probed during the interview to determine the source of their many career changes. Were the answers something that you were willing to accept? What kind of investment do you make in a new employee? Does getting this particular person into your organization off-set those costs that you are putting at risk? If you're hiring them through AppleOne, have you asked your account executive about the 5-50 Assurance Plan? That can protect your investment for up to 5 years, so it could be very useful in a situation like this. These are all questions that only you can answer, but they are questions that you should definitely be asking yourself before moving forward.
In the end, trust your instincts and don't allow yourself to get frozen into inaction because you don't want to make a mistake.
