? Make sure your candidate really knows the job. If your CMO-to-be doesn't know the difference between marketing and sales or your CFO can't tell you the difference between LIFO and FIFO, pass 'em by.

? Interview for chemistry. Do you trust this candidate? Do you want to spend time with them? Believe me when I say, you don't want an abrasive team member, no matter how talented they may be. One COO I know, scared to make the hard decision, reorganized his entire company around a highly talented, incredibly obnoxious executive that everyone despised. The exec's talent got to shine--but everyone within 100 yards quietly subdued theirs.

? Talk to people from your candidate's former company. Are the candidate's claims of divine brilliance reflected in what their former peers and subordinates have to say about them? Find out if they got the work done and also how they contributed to the company's culture. In a small business, cultural issues can be every bit as important as getting things done.

? Always hire really smart people. Here's a good guideline to follow: Every new hire should increase your company's average IQ. That means they should all be smarter than you. Get used to it.

? Look for evidence of learning ability. Will your candidate repeat mistakes they've made in the past? Or will they learn from those errors and adapt that knowledge to your company?

? Use "behavior description interviewing" techniques. Don't ask about principles, knowledge or "what if" stories. Instead, ask your potential executive team member to share specific past events. Their stories will reveal their values, skills and abilities. For example, you might ask a CFO to describe a budget they set up and how they handled it when a manager exceeded their budget and asked for more.

One word of caution: Be wary of hiring friends or family members. They'll expect you to trust them and just assume they have a high skill level. What's worse, you may trust them and assume they have a high skill level without any evidence to the contrary until after you've hired them. And unless you take care to be very clear about the boundaries between friendship and work, you may find your friendship in ruins over workplace disagreements.
