Twitter Summary: You are going to spend a lot of time with your early hires. Make sure you enjoy their company.
A special case in interviewing is finding and assessing co-founders and early employees. The first hires are critical as they will help dictate the direction and eventual outcome in success of the company. The interview process for early employees is different in that the people you are typically interviewing are referrals or perhaps “friends of friends.” Generally these are people who have been successful in some other organization and your job is to determine if they can successfully help you bootstrap your small organization. Spending extra time with them during the interview phase is especially important as you will be spending many more hours with them getting the company off the ground.
The interview questions in this case are not very different. However, the skill set you are hiring for is broader and personality attributes are much more important. Interviewing early employees should take more time as you need to assess if they have all the skills you require. Following up with the referral candidates is also critical. Even if the candidate is not offered or decides not to accept a role they may turn into an invaluable resource for other future hires.
Key traits to look for in early hires are:
- Can you spend a lot of time with them?
- Rather than a 1-3 hour interview, spend a full day with each other talking about the business or social matters.
- Consider taking a trip with a potential candidate to a client site to see if you would enjoy working with them.
- Would you want to be in a foxhole with this early member?
- Does the candidate have a wide range of skills or more importantly the enthusiasm to do things beyond their skillset in order to get what needs to be done completed.
- Consider asking the candidate how they deal with stress, both their own and others? Startups are by definition stressful environments and having a candidate who is self-aware to provide a good answer with examples is really important.
- How do they deal with ambiguity?
- All early stage companies lack phone systems, HR resources or people to help with basic maintenance tasks. In the absence of information, a policy or even an ability to do something, what is their approach to make sure the task is completed.
- If the garbage is overflowing do they (a) Take it upon themselves to do it, (b) complain about the garbage overflowing, or (c) create a schedule to rotate who takes out the garbage until an office manager or someone is hired to take care of it as a permanent responsibility.

Twitter Summary: A great hire will often generate lots of energy during a hiring meeting and some of it negative.
Once you have established whether a candidate passed your interview, the final step is to have a hiring meeting where all the interviewers provide their assessment of the candidate. The hiring meeting is important to attend in-person for multiple reasons: a) You are compelled to make a decision as you have a scheduled time and duration to decide on a candidate, b) You can confirm or provide counter-evidence for skills or behaviors people saw during their interviews, and c) You can calibrate with your team whether you are all asking the right questions with the right degree of difficulty. Email doesn’t work in this context as in-person dialogue allows the team to quickly clarify questions among all interviewers.
How do you decide if you are going to hire someone? The best technique I have seen to date has been requiring unanimous consensus by all the interviewers that the candidate should be hired. The tremendous flaw of this style of decision making is that it will reject candidates who could have done well at the company, but because of a sub-par interview, they are eliminated from consideration. The incredible advantage of consensus driven hiring is that everyone who is hired has had at least six people say “Yes” to hiring the candidate. If all of your colleagues have gone through the same process to join the company you should have more confidence that they are doing the right thing. If a co-worker begins having difficulties, there should be a sense of ownership by the team that they picked the candidate for a reason and they can help them work through those issues.
It is important to note, that consensus means that everyone agrees the candidate should be hired. It does not mean that everyone likes the candidate. Some of the best employees I have ever hired had at least one or two other interviewers indicate they were not inclined to hire. There have been cases where a college intern was determined to be a great hire by two of their interviewers, and a strong no-hire, by their other two interviewers. This intern was fortunately hired and ended up being an exemplary hire for the company as the advanced and took on more projects quickly. It was fortunate that in these cases the candidate was able to express a deep technical capability and being a “superstar” in some fashion that an interviewer was willing to champion them in the hiring meeting to take a chance on a hire. The dissenting interviewers shouldn’t ever be bullied into hiring a poor candidate, but they should be open to listening to the interviews of others and decide if it is worth the risk of sharing a payroll with the new hire.
Some of the most questionable hires have been hiring meetings where the candidate did well enough that everyone was inclined to hire, but no interviewer was able to figure out where the candidate was great. The problem with hiring these candidates is that they frequently have a similar career within the company of doing good but not great. Finding a passion or the superlative associated with each candidate means that if they decide to join the company you will increase the overall depth of your company’s employees and the probability that something great will emerge.
Twitter Summary: The questions you pose to interviewing candidates reveals if your job is interesting or boring.
The questions you ask and your assessment of the candidates answers comprise the core of the interview. More importantly, excellent candidates will be paying attention to you and will be assessing you just as much as you are assessing them. If the questions you ask are the same the candidate has heard in other interviews, seen in interviewing manuals, or from another interviewer that day, they will have a clue that your interviews are not organized, your questions aren’t relevant, and that you may not be capable of capturing the depth and breadth of their capabilities.
Great interview questions have the following qualities:
- The problems you ask them to solve should either be ones that you are familiar with or are currently trying to solve yourself. This gives the candidate a clear indication of the type of work they will be asked to perform. This also gives the interviewer the ability to assess how the candidate would solve a problem that is pressing for the organization right now.
- If you are interviewing a software engineer for a kernel development position, ask them to code a scheduler and talk about memory allocation.
- If the candidate is interviewing for a social networking site, ask the candidate to generate code to generate a user to user similarity score.
- If the candidate is interviewing for a marketing position, ask them how they would evaluate marketing options for your current product.
- Don’t ask a “textbook” questions. — For software engineers, this means asking them to implement “atoi()”. For anyone it would mean questions like: “What is your greatest strength?” Your questions should be open enough that the candidate reveals their strengths in the process of describing another problem they solved.
Expandable in depth and breadth
- The questions you ask should be expandable in either breadth or depth. For software engineers, this would mean asking them to take their solution and and scaling to handle millions of users or machines, or alternately asking them to change their solution to handle multiple, media and content data types. For product or marketing candidates, you could ask them how they would modify the programs or projects to deal with if you wanted to handle a larger diversity of customer groups or a broader product line.
- Don’t ask questions with only one right/wrong answer. Asking questions that have only one correct answer is problematic as it doesn’t give the candidate the opportunity to discuss trade offs in choosing and decision making. In the end, you are hiring people to make judgment calls, and are not hiring a computer to give you a rote answer
- Present only the basics of the problem. The interview should be a dialogue, and interviewers should intentionally give less information then the candidate needs to solve the problem. This will get require them to ask you clarifying questions and give you insight as to how they approach their problem solving.
- Don’t spend all your time talking. If you spend most of the time talking you are not getting the information from the candidate you need to make your decision. You can spend more time talking with the candidate after they have answered your question, and especially if they are hired.
Great inteview questions make your job as an interviewer easier . A great set of interview questions will allow you to understand how the candidate would solve the problems you need to solve in your company, how the candidate deals with challenges as the problem expands, and how they communicate and ask for more information in answering the question. It also tells the candidate about what problems they can expect to be solving and if the role is a match for what they want to do.
Twitter Summary — If after interviewing a candidate, you are unable to make a Hire/No Hire decision, you have failed as an interviewer.
Interviewing candidates involves making a judgment call about the person you are interviewing. One thing that makes this difficult is that there are many resources (web based, books, college or career counselors) who can give a candidate the “right” answer for just about any question an interviewer can ask: “What is your greatest weakness?”, “What is your biggest strength?”, “Where do you see yourself in 5 years? 10 years?” Admittedly, offering this information is an attempt to help others who are interviewing answer the questions “well enough,” but often mask what you really want to know about the person. This puts the interviewer into a situation where they will not be able to make a clear decision on a candidate. When candidates answer all the questions “well enough” they run the risk of hiring someone that will only do “well enough” at their company.
My biggest difficulty in interviewing is when I find I personally like the candidate and think they would be great to know outside of work based on shared personal interests that come up in the course of our conversation. However, shared personal interests is not a determining factor as to whether a candidate can match all of the expectations of a role. The sole job as an interviewer is to form an opinion of a candidate and decide whether they are qualified for their role, and will excel in that role for the company.
The keys to success in interviewing a candidate are:
- Be present — Make sure that your phones and computers are off, and you have space where the door is closed. Distractions that pull you away from focusing on your candidate shortchanges the candidate and your opportunity to make a clear decision. As most interviews last only 45 minutes to an hour, your undivided attention is important in assessing the candidate.
- Assess for your “hidden agenda” — We all look for the same attributes for a candidate: Are they smart, punctual, enthusiastic, hard working? You cannot ask those questions directly, as the answer anyone would give to them would be “Yes.” Instead, you should ask questions like: “What was your favorite project?” and in their response you listen to see if the project was successful and required smarts, or enthusiasm, hard work or punctuality to solve.
- Communicate using multiple methods — Require the candidate to communicate using graphs, words, speech and even assess non-verbal communication, regardless of role. As a future employee, the candidate will need to work with many people in the company and needs to be able to communicate to anyone using whatever technique is most important at the time. By assessing the spectrum of the candidates ability, you will hire people who can express themselves and represent well within the company. The non-verbal communication is important to assess the confidence of their responses. If they are not confident in their responses with you during an interview, they will lack confidence when communicating with their colleagues
- Induce Stress — During the interview you should create some conflict that the candidate needs to justify so that you can see how they manage stress. Stress is a fact of life at companies and is important to assess during the interview. The stress doesn’t need to be excessive, but by requiring the candidate to deal with stressors on their feet you can get a good idea of how adaptable they are to the environment. The most appropriate ways I have done this during interviews have been to either (a) repeatedly change the requirements of the system (steadily increasing the scope of the project as they answer each part successfully), or (b) express to the candidate that I think there can be a better solution using technology X, and to justify their use of technology Y. Get the candidate to discuss the tradeoffs and assess the impact of the stress.
- Choose your questions well — The questions you select for a candidate need to be the ones that allow you to make a “Hire” vs “No Hire” decision within the allotted time frame. If you are not asking questions that get you to the point where you can make a hire decision, you are asking the wrong questions. Don’t waste the candidates time or yours by asking questions that don’t help you assess a candidate.
- Look for the superlative — The thing that distinguishes the “Good Enough” candidates from the “Must Hire” candidate is typically a superlative where the candidate was the “Best” at something. Typically this comes up when the candidate mentions they were the “go-to” person for certain areas or solely responsible for certain pieces of technology. Assess why they did so well in those areas and make a determination if that would be important for your company.
- Take Notes — If you interview many people a day, you should write-up your notes immediately afterward so that you don’t confuse candidates and can discuss the candidate during the interview debrief. Notes also help to re-enforce a second pass assessment of the candidate to see if they matched the requirements for your “hidden agenda” or had a “superlative” associated with their prior work experience.
Interviewing takes lots of focused listening, but once you have identified a candidate to interview they deserve the attention you give to them. This attention is how the candidate assesses your non-verbal communication and gives the candidate the confidence that a “hire” or “no-hire” response from you company was the correct decision for you and them.
The next in the series will cover “What” you should ask during an interview.
Twitter Summary: You have more leverage to influence the direction of a company by the people you hire then what you do.
In my career so far, I have interviewed well over 1000 people. I developed a reputation for being good at it which meant I was interviewing software engineers, product managers, engineering managers, VP, CTOs, and even prospective new attorneys which is far out of my core expertise. My job was to assess their ability to be good at their position and to help figure out if they would be successful within the broader context of the company.
I frequently get groans from engineers about how much of their time interviews consume. In fairness, a badly scheduled interview will fragment a developer’s day to be unusable and developer’s want to spend the time doing what they were hired to do. Unfortunately, a well run interviewing effort typically takes multiple hours of time if you have:
- Phone Screen — Assess if there is a match to the position you are looking to fill.
- Pre-planning — Scheduling and assigning interview roles and competencies to assess.
- Interview — Spending the time to figure out if this is someone you would like on your team.
- Debrief — Write up of interview and discussing whether the candidate is a match.
In spite of the time sink, as an employee you should be on as many interview loops as you can handle and make time to schedule. The benefits of interviewing are tremendous to both your quality of life and the future success of your company. The two reasons to do this are:
- You get to decide who works with you! — Never are you more influential in your own work life then when you get to decide which colleagues you will work with daily. That interview process is crucial to figuring out: Is this candidate smart, innovative and adaptive to your environment? Can this candidate help me solve my problem? What about if the problem occurs at 2AM? Will this colleague help me make a right decision and support me, or will the colleague argue with me when I am wrong and explain it in a way I can understand and agree?
- You are helping direct the compass of the company. — The people you hire are the mission statement of the company. By hiring people that not only have a talent for their role, but also have abilities in other domains you get to broaden the reach of what your company can do. If you hire only system kernel engineers, you shouldn’t be surprised if the next innovation is a recommendation to rebuild a new O/S. If you hire framework developers, you will inevitably be requested to approve a new framework that will help develop your product. If you hire a diverse set of talent that can do their jobs, and also innovate in new directions, you will be able to innovate in many new directions. The abilities of the people you hire, will help dictate what will be considered the “core competency” of your company, and which features will be outsourced to different companies.
Yes, interviewing can be time consuming. However, you can assist in planning your schedule so that interviews are less intrusive, because the benefits are immense for your day-to-day work environment and the future success of your company.
