Carpenter Interview Questions

Question: Do you have carpenter experience in residential, commercial, or industrial work?

Explanation: This is a general opening question in which the interviewer will ask you to begin the conversation, learn more about your background, and solicit some information they can use for subsequent questions.

Example: “My experience as a carpenter spans many industries. I’ve done both rough and finish work on residential buildings, worked on some large commercial projects, and even helped in an industrial setting as an in-house carpenter. I am very confident I can do the type of work your organization is engaged in.”

Question: Do you know how to operate a scissor lift? If so, what safety precautions are required?

Explanation: As a carpenter, you can anticipate the majority of questions you’ll be asked during an interview will involve your experience, skills, and capabilities. The employer is looking to confirm you will be able to do the work required by the job and have experience in the specific areas they are engaged in.

Example: “I have used scissor lifts on many of the jobs I’ve worked on, and I am comfortable operating this machinery. I am fully aware of the safety precautions required. These include wearing restraints while in the cab, making sure the area is clear and roped off so nobody can enter while I’m lifting materials, ensuring the load is well within the machine’s capacity, and always having an assistant available.”

Question: What are some jobs you would use a welding machine for?

Explanation: When asking questions to learn about your capabilities and background, the interviewer will use this type of operational questions to explore your ability to do a specific task or job as a carpenter. Operational questions are best responded to directly and briefly.

Example: “There are several jobs on a construction site that you can use a welding machine for. The most obvious is putting steel girders in place and welding the joints. You can also use a welding machine to create HVAC ducting and fabricate things like stair railings and other metal support objects.”

Question: What types of information can you gather from a blueprint that would help you on the job site?

Explanation: The ability to read blueprints is critical for a carpenter. You should be able to describe some of the takeoffs you get from blueprints that help you perform your job. Since this is an operational question, keep your answer short and to the point.

Example: “Blueprints provide a wealth of information for carpenters working on a construction project. I don’t believe I could do my job without them. Not only do they provide the dimensions required, a bill of materials, and detailed drawings of the project, but they also indicate where non-carpentry related items will be placed such as plumbing and electrical.”

Question: What does the abbreviation BOF indicate on a blueprint?

Explanation: This is a follow-up to the previous question. During an interview, the interviewer will ask follow-up questions to get more information from you or dive deeper into a topic. You should anticipate a follow-up question every time you answer an interviewer’s query.

Example: “BOF on a blueprint indicates the Bottom of a Footing. This describes where the footing interfaces with the baseplate. It usually indicates how the footing will be attached to the baseplate and what additional reinforcements will be required, if any.”

Question: What steps do you take to ensure your measurements are accurate?

Explanation: Maintaining accuracy in your measurements is a critical element of being a carpenter. This not only ensures the pieces you cut and install will fit where they are intended to, but also that you are not wasting material by having inaccurate measurements that need to be redone. You can address both of these issues when you provide your answer.

Example: "First and foremost, I always measure twice and cut once to ensure my measurements are accurate. I also take time to refer to the blueprints before I begin taking any measurements. I will often write the critical dimensions down so I can reference them while making cuts or installing components of the construction. If there’s any doubt in my mind, I will ask one of my co-workers to verify I am interpreting the measurements correctly. All of these actions contribute to not having to do any re-work and not wasting materials."

Question: If you are working on a roof and your safety gear is hindering your movements, what can you do?

Explanation: Safety on the job site is a constant concern for a construction company. Jobsite accidents cause delays, cost money, and have an impact on individual workers. Given a choice, carpenters should always take steps to ensure their safety and the safety of their co-workers, even if it means taking longer to complete a task.

Example: “When working on a roof, I always make sure to wear a harness with a safety line that is securely anchored. While this impedes my movement and sometimes gets in the way, it also gives me the confidence to move around with the knowledge that if I do fall, I will be safe. Even when the equipment hinders my movements, I keep it on and just work around the obstruction the best I can.”

Question: Describe how you would install a window.

Explanation: This is an operational question in which the interviewer is asking you to walk them through the process of completing a task on the construction site. When asked this type of question, you should break your answer down into each step you take. However, avoid the temptation of providing too much detail. Keep in mind the interviewer will ask a follow-up question if they need more information.

Example: “Installing a window requires several different steps. The first is to ensure the frame is straight and level. I then place waterproof material around the frame. Next, I put the window into the frame and square it up as best as possible using shims. I nail the window into the frame, ensuring it is plum as I proceed. Finally, I test the window to make sure it operates properly. After it is installed, one of my co-workers or I will trim it out to make it look good.”

Question: What factors do you need to consider when building a set of stairs?

Explanation: Building a set of stairs is one of the most complex jobs a carpenter can perform. By being able to describe the factors you consider when doing this, you will communicate your qualifications as a carpenter. Again, keep your answer brief and concise and anticipate follow-up questions from the interviewer.

Example: “When building a set of stairs, I first measure the height between the floors and the length of space the stairs need to fit into. I then calculate how many steps will be required. This is based on the standard rise of each step and the length of the tread. I make sure to take into account the materials used and any covering they may have, such as carpeting, when doing my calculations. Finally, I have another carpenter review my design before I proceed to build the stairs.”

Question: Have you ever worked on a project that was behind schedule? If so, what did you do to speed up the process?

Explanation: Construction projects are notoriously late and over budget. Taking steps to deliver the project on time and within budget is critical for the construction company and the carpenters working on the project. Anything you can do to contribute to this will benefit the employer and provide them one more reason to hire you.

Example: “While working on a project, I do my best to keep my portion of the job on time and under budget. If for some reason we fall behind schedule due to a lack of materials, weather, or some other factor, I take steps to make up the lost time without sacrificing the quality of work. These can include staging the materials before beginning construction, using automated technologies such as nail guns and laser measures, and working in teams so we can move faster.”
