Interview Questions for Home Performance Salesperson Candidates

So, you want to interview a sales candidate? What questions should you ask?

Let’s start with the assumption that you are NOT making the mistake of winging it. You’ve thought about the key characteristics for success. (See my earlier post on “Six Ways to Hire the Wrong Home Performance Sales Candidate“.) Now, you want to ask questions that tease out how well the candidate embodies those characteristics. And you want to make sure that the best sales job the candidate does is the one he or she does to get a job with you!

I think one important approach here is to use questions that get at behavior rather the recitation of facts. What would the candidate do? And, unlike stock market funds, one of the best predictors of what a candidate will do in the future is what they’ve done in the past. Ask them what they’ve done, and you’re looking for both performance results and behavior.

Another thing I recommend it tailoring the questions to the candidate. Do YOUR homework, and you’re better positioned to ask the right questions, questions that get to the heart of what that candidate would do for you and your company.

Let’s explore this with some sample categories and questions. Again, you want to focus on those categories you’ve determined are most important for your candidate, not necessarily those listed below.

Warm-up Questions

  • Tell me about yourself? 
  • What are you doing for EnergyWorks Contracting right now?
  • What are some of your largest accomplishments?
  • What did you learn in your research about our company that interested you enough to come here today?
  • What do you like least about being in sales?

I want to see how the candidate interacts a bit before the questions get more direct. And I want to see how well he or she has prepared to handle a few of the expected questions.

General Sales Skills

  • I see you’ve worked at _________ (commercial? residential? size?). What experience do you have selling for companies our size? In residential sales?
  • How did you prepare for your last sales call?
  • What was the toughest sale you made last year?
  • What caused you to lose the last deal you lost? 
  • And then after response, What could you have done differently to win that sale?
  • Describe your sales cycle? [How does that compare with the sales cycle in your company? Watch out if it’s a very different cycle than what is needed in your home performance business.]
  • Tell me about the sales process you use. Walk me through it start to finish.
  • How did you prepare your sales presentation for Energy Works Contracting?
  • How can I contact the managers for whom you’ve worked in the past?  And then, How would your (former) supervisor describe you?

Here’s a big mistake the home performance world makes. Too many think the the audit sells itself. It doesn’t. You have to sell improvements (unless you expect the government or ratepayers to pay the freight–in which case you’re not in the right place). Previous sales successful experience–especially residential, in-home sales–should be a good predictor. So we’re asking first whether their experience is relevant and translatable. And then next, if they can produce the numbers you need:

Sales Production

  • Tell me about the past year’s sales you generated at Energy Works.
  • What did you do your first year there?
  • What was the size of the largest sale, second largest sale and third largest sale in both the first and the last year? How did you get them?
  • What was your sales quota?  How often did you make it?  And what did you report on your taxes?
  • How is your quota determined? How do you monitor your progress toward your goal?
  • How have your sales goals changed over each of the last 3 years?

What to look for: Can they sell at at least the minimum levels you need? Are you expecting them to sell more than they’ve ever sold before? [If so, how will you help this do that?!] Do they have goals? Have they shown growth? 

The above would be my top two areas to explore. But having done your homework, you should have a few additional criteria you’d like to measure them against.  Below are some examples. They may or may not be the important ones for you. What would YOU like to see in a candidate?  You don’t have to ask all of these questions–and certainly not in a first interview. But if you’re going about this right (instead of wrong), you should have time to explore the important areas in follow-up interviews and with variations of the questions when checking references.
