Interviewing at Twelve: What to Expect

Updated: Oct 14
Finding the right next opportunity is a big decision. This guide is designed to give you a clear view of what to expect during the Twelve interview process, from your first conversation through final interviews.

Building a New Era for Industry
For 150 years, industry has been built on the same basic foundation. Twelve is building what comes next.
Our technology turns CO2, water, and electricity into the fuels and chemicals that underpin the global economy. AirPlant™ is where that technology becomes industrial reality: bringing together first-of-a-kind technology, infrastructure, engineering, manufacturing, and operations to produce products made from air at commercial scale.
As we build and scale the next generation of AirPlants, we are growing a team of people who know how to solve hard problems, build real things, and turn ambitious ideas into operating industrial systems.
That includes expertise across engineering, construction, manufacturing, operations, commissioning, technology, safety, supply chain, commercial functions, and more.
Just as importantly, we want the interview process to help you understand Twelve, the work ahead, and whether this is the right place for you.
What to Expect During Your Interview Experience
Our interview process is designed to understand your experience, how you approach problems, and how you work with others. It is also your opportunity to learn about Twelve, meet the people you may work alongside, and get a clearer picture of the role.
The exact process varies depending on the position, but most candidates can expect some combination of the following stages.
1. Recruiter Conversation
If your experience looks like a potential fit, a member of our Talent Acquisition team will send you an email with a scheduling link for an introductory conversation, typically 30 minutes by Teams video.
We’ll talk about your background, what you are looking for next, the role, and the work happening at Twelve. This is also your opportunity to ask questions about the team, our AirPlants, our technology, and what it is like to work here.
If there is a strong match, we’ll invite you to continue the conversation with the hiring team.
2. Hiring Manager Interview
The next step is typically a 30 to 60 minute conversation with the hiring manager. We’ll go deeper into your experience, technical or functional expertise, and how your background connects to the challenges of the role. For many of the positions supporting our AirPlants, that can include experience building, scaling, commissioning, operating, or improving complex industrial systems.
You’ll also have time to learn more about the team, the work underway, and what success in the role looks like.
Come with questions. We want this to be a two-way conversation.
3. Technical Exercise or Assignment
Depending on the role, we may ask you to complete a short technical exercise, case, or assignment. We respect your time and design these exercises to take no more than one hour to complete.
The format will vary by position. You might be asked to analyze data, troubleshoot a technical problem, review a process or system, work through an engineering scenario, or present how you would approach a specific challenge.
We are interested not only in the answer, but in how you think. Show us how you frame the problem, work through uncertainty, make tradeoffs, and arrive at a solution.
4. Final Loop Interviews
Candidates who advance to the final stage typically participate in a series of one-on-one or small-group interviews.
A final loop often includes four to six conversations lasting approximately 30 to 45 minutes each. Depending on the position, these may take place virtually or onsite at one of our locations.
Each conversation generally focuses on a different area, such as technical expertise, problem-solving, collaboration, leadership, execution, or relevant functional experience.
For certain roles, the loop may also include a technical exercise, whiteboard session, presentation, site or lab tour, or collaborative working session.
The goal is to understand how you would approach the real work ahead at Twelve and to give you meaningful exposure to the people, environment, and challenges you could be joining.
Sample Final Loop for an AirPlant Engineering Role
15 minutes | Site, Plant, or Lab Tour
45 minutes | Candidate Presentation
45 minutes | Technical or Problem-Solving Session
30 minutes | Lunch with the Team
45 minutes | Technical or Cross-Functional Interview
30 minutes | Behavioral Interview
15 minutes | Questions + Wrap-Up
Your exact schedule will depend on the role.
Preparing for Behavioral Interviews
For behavioral questions, the STAR method can be a helpful way to structure your response:
Situation: What was the context?
Task: What problem, responsibility, or objective were you working toward?
Action: What did you do?
Result: What happened as a result?
Specific examples are useful. Tell us what the situation was, what decisions you made, how you worked with others, and what you learned.
Different Roles, Different Processes
We are hiring across many disciplines and levels, so not every interview process will look the same.
Some roles may require fewer conversations. Technical positions may include deeper technical assessments. Roles connected to construction, commissioning, operations, or plant execution may include conversations with several cross-functional partners. Senior leadership positions may include additional stages.
Your Talent Acquisition partner will explain the process for your specific role and help you understand what to expect at each step.
What We Want You to Get From the Process
Clarity. You should understand the role, the team, the expectations, and the work ahead.
A real view of Twelve. Ask us about the technology, AirPlants, how teams work together, the challenges we are solving, and what it takes to build first-of-a-kind industrial systems.
The opportunity to evaluate us. An interview is a two-way decision. We want you to have the information you need to determine whether Twelve is the right environment for you.
Open communication. If you have questions about the process, need clarification, or require an accommodation, your Talent Acquisition partner is here to help.
What Happens After Your Interview?
After your final interview, our team will follow up with next steps as quickly as possible.
If we move forward, we’ll walk you through the offer, compensation, benefits, and what to expect as you prepare to join Twelve.
If we do not move forward with the role, we appreciate the time and energy you invested in getting to know us and encourage you to stay connected as Twelve continues to grow.
Candidate Experience Survey
If you reach the hiring manager interview stage or beyond, we may send you a short candidate experience survey.
Your feedback helps us understand what is working and where we can make the experience better for future candidates.
Build What Comes Next
Twelve is building more than a new technology.
We are building real plants, real products, and a new industrial platform for making the molecules the world runs on.
Every AirPlant™ is another step toward that future.
And building it takes people who are curious, ambitious, collaborative, and ready to solve problems that have not been solved before.
If that sounds like you, we want to meet you.
