Hiring good employees is a primary responsibility of managers. That being said, any manager who says they have never made a bad hire, simply hasn't hired many people. Every hire is a gamble made with very little information. This post is an attempt to arm the manager with some tools that will help them gather as much relevant information as they can in the one or two hours they get with a candidate before deciding who is the best candidate for the job opening.
A manager can improve their chances of making a good hiring decision by having the candidate interview with as many people as is practical. It is their own judgement, however, that carries the most weight. For the purposes of this post, it is assumed that the manager and HR have done their job in creating an excellent job description and have lined up several seemingly qualified candidates.
The keys to an effective interview are as follows:
- Preparation of an interview worksheet tailored to the position.
- Thorough review of the candidate's resume and cover letter.
- Execution of the interview
- Post interview summary
- Bonus - Reference check questions
Let's take them one at a time.
Preparation of an interview worksheet tailored to the position.
An interview worksheet is simply a list of questions that are designed to give the interviewer a thorough understanding of the candidates experience, expertise, and motivation for the position. By using the same, or similar, questions for all of the candidates provides a level playing field for all candidates. Once a good interview worksheet has be created for a particular position, it can be saved and reused whenever that position is required. This allows the worksheet to evolve over time to become increasingly effective and a manager can tailor them to new companies or situations. Obviously the questions will be different for a manager versus an individual contributor, or an accountant versus an engineer, but some questions are relevant to all candidates. The worksheet should have a space for the candidates name and date at the top of the first page and no more than 6-10 questions should be printed on each page to leave space for writing the candidates answers, or interviewer observations, feelings, or other comments.
The interview worksheet, and therefore the actual interview, should have four sections.
- Work History
- Technical
- Motivation
- Business Personal
1. Work History
This is the section where an interviewer learns about items in a candidates resume and cover letter that are relevant to the job, What companies have they worked for, what were their positions, who did they report to, etc. Additionally, this section is where any questions generated from the resume review will be asked. There may be many things about the job opening that are not in the resume, and those things will be covered in the Technical section. Here are several questions that might be asked in the Work History section. Notice that most of the questions are written exactly as they would be asked.
- Tell me about your last company, including size, organization, scope of your position, who you reported to, where did you fit in the organization, what do they make? This question can be shortened or expanded depending on whether the interviewer is already familiar with the companies where the candidate has worked. It can also be broken up to ask several questions instead of one long question.
- Who were your main customers at _____? What percentage of your time was spent with customers?
- You mentioned that you increased profits at _____. What exactly did you do?
- Your resume states that you improved the safety record at several companies. How did you do that?
- What coding language did you use at _____ and ____. Which one did you like better?
- How often did you close the books at _____. What was your role in the close?
- Why did you leave ______. It looked like you were very successful there?
- What ERP system did they use at _____. How proficient are you in using it?
- What reports did you develop to manage your department at _____?
- What accomplishment at ______ are you most proud of?
- What would your subordinates at ______ say about your management style?
2. Technical
This is where the interviewer explores the candidate's background concerning the specific technical aspects of the job. These may or may not be in the candidate's resume. In some instances a candidate may not have any experience in a particular area, but can still discuss what they would do in a given situation, or how they would handle a new challenge. Here are some possible questions:
- What is the role of the Document Control Manager in handling new products?
- Describe a difficult personnel situation you experienced and how you handled it. How would you do things differently today in the same situation?
- How much do you know about California Employment Law?
- How often do you recommend reconciling balance sheet accounts?
- How often did you have to deal with lawyers? What are some examples?
- How would you approach an initiative to reduce product costs ( labor costs, programming costs, freight costs, travel expenses, etc)?
- What would you do to improve inventory accuracy?
- How would you handle an upset customer? What would you do if there was no way to satisfy them?
- Explain your experience with inventory valuation (tax preparation, cost accounting, payroll, AR collection, AP - discounting & payment philosophy, working capital management & control, budget preparation, asset management, product costing, etc).
- How would you improve inter-departmental relations between Ops, Finance, Sales, Marketing, Customer Service, HR, Quality, R&D, etc. (pick two)?
- How do you measure the success of a sales person (hit rate, volume, margins, customer feedback, etc.)?
3. Motivation
In this section the interviewer is trying to find out what makes the candidate tick. What is important to them. What do they like and what type of environment is right for them. Here are some typical questions:
- What part of your job do you enjoy most? Why?
- Explain a situation, or a few situations, where you showed initiative - what were the reasons for the effort. What were the results?
- What characteristics do you possess that have helped you be successful?
- Explain a failure on your part and what you learned from it.
- What is the ideal work situation for you?
- What is the ideal relationship you would like to have with your supervisor?
- Why are you interested in our company?
4. Business Personal
Always be careful to call these questions "business" personal and not just personal questions. It can be seen by the questions below that all of the questions are appropriate to be asked, but if you say to a candidate that you will be asking them personal questions, they may become apprehensive about the type of questions that will be asked. Here are a few:
- What did you like least (best) about the job at _____ ?
- How important is the title to you?
- How long is the commute? How do you feel about it?
- How is the search going?
- Where would you like to be in your career in 5 years?
- Why are you looking for a new job?
- What questions can I answer for you?
Thorough review of the candidate's resume and cover letter.
Although some people still swear by them, I have found cover letters to be essentially a waste of time. However, if one accompanies a resume of a candidate that will be interviewed, it should be read. The resume, on the other hand, is essential. The interviewer should have only two things in front of them when interviewing a candidate, and they are the candidate's resume and the interview worksheet. I recommend highlighting anything in the resume that the interviewer may want to refer to during the interview. The Work History section of the interview worksheet should be updated with a few questions that come directly from the resume.
Execution of the interview
There are some obvious hospitality items that should be mentioned. Make sure the interview is conducted in a quiet comfortable place. Offer the candidate something to drink. If the interview will be conducted in the manager's office, turn off the phone and don't allow any non-emergency interruptions. Describe for the candidate the four sections and that the interviewer will be writing constantly, but to ignore it. Do not sit in such a way that the candidate can read what is being written.
Try to be consistent in writing things down and don't only write just after the candidate has said something. The things to write down are a combination of several things, including what is said, the impressions the interviewer gets from the candidate, follow up questions to ask later, unrelated questions or comments that are relevant, etc.
Don't allow the candidate to ramble. Once a question is satisfactorily answered (or not), stop the candidate and move to the next question. It may be useful to tell the candidate that this will happen and it shouldn't be interpreted as not wanting to hear what they have to say, but that time is limited and there are a lot of questions to ask.
When asking questions, there are really three things to determine.
- What was done - This means what did the candidate do specifically. How did their specific actions impact the result. The more detailed a person's answer, usually the more they know what they are talking about.
- What were the results - Again there should be a direct correlation between what was done and what was achieved. If the candidate does not see this connection, they probably weren't the real driver of the results. It could be that they were told what to do and they did it. That may be OK for the current job, but maybe it isn't.
- Why was it important to be done - This is a little more subtle. In the universe of things that could be done, and with limited time and resources, why did the candidate pick this item to do and highlight on their resume or in the interview. It may be that they were told to do it, or that it was obvious, but maybe they have another reason.
Don't feel obligated to ask every question. If a question was already answered previously, or just doesn't feel relevant, skip it. If the interviewer decides early in the interview that the candidate is not suitable, still ask one or two questions from each section. Do not abruptly dismiss the candidate. The candidate has gone to a lot of trouble to be seated in front of the manager and deserves to be interviewed seriously. That does not mean to spend the maximum time, but enough to show the candidate the right level of respect for their time.
Post interview summary
After the candidate has left, and ideally immediately after, the interviewer should write a few paragraphs on their impressions of the candidate, both positive and negative. This is very important. If several candidates are interviewed for a position and an obvious winner is not apparent, it is the summary that will be referenced most often. Most people will not go back and review every answer, but will definitely reread the summary. I also strongly recommend spending a few minutes going back over the worksheet to make sure what was written will make sense later. The interviewer's shorthand during the interview can be indecipherable later, even to them.
Here is the bonus
After a candidate is selected, references should be called. Most people who serve as references are given by the candidate and will be an advocate for the candidate. There is nothing wrong with that because most people won't outright lie. Here are some questions to get a person to give a more balanced view of a candidate.
- What was your relationship with _____ ? Do you remember their exact title?
- How long did you work together?
- ____'s management style seems very developed and effective, is this how you remember them?
- Since I will be _____'s direct manager, where do you think I could best help them develop in their career as a manager?
- Why did they leave?
- Would you hesitate in putting _____ in front of the CEO, or important customers? How do you think they would perform in those situations?
