What are we testing for?


We’re trying to evaluate whether you’ll be a high performer at the role you’re applying for, and whether you’re a good cultural fit with our values. These are:

  • Do the right thing

    Ultimately we're here to mitigate climate change. Sometimes we will have to trade off what clients want, what we want, and the right thing. We do the right thing.

  • Run fast but change direction easily

    We go all in, until we change our minds. We're not afraid to change direction and ditch ideas.

  • We’re constantly learning

    We rely upon the diverse expertise of our team to solve hard problems, and everybody has things to learn. We can all learn from one another.

  • People, product, planet

    We invest in our people; that's where we start. Happy, empowered people → build great products → good for the planet. 

  • Think Gigatonne

    We're not here to count grams of carbon. The climate crisis requires us to aggressively decarbonize. Dream big and act bold.

  • We win when customers cut carbon

    Our customers' successes are our successes. Our path to impact is via our customers. We strive to help them decarbonize their organizations.

  • Correctness over consensus

    We bring strong but loosely held opinions, and find the best ideas in the group. We care about getting our numbers right.

  • Fail fast and loud

    We celebrate wins but we scrutinize failures. We learn best by taking lots of risks and analyzing when they don't work out.

  • Bias for action

    Good now is better than perfect later. We're in a climate emergency. The clock is ticking.

  • Act like an owner

    Own your tasks and your expertise. We do what we say we will do.

Throughout the process, you can expect to be asked questions which evaluate how well you’ve exhibited these values in your previous roles and projects. We love to hear about specific examples where you’ve really embodied these principles.

The process


☎️ Initial phone screen

If your cover letter and CV look like you might be a good fit for CarbonChain, the process will begin with a phone screen.

This is a 30-60 minute call with somebody who is doing the role you’re applying for, or manages that role.

They’re trying to understand:

  • What motivates you to come and work at CarbonChain?
  • What involvement did you have in the projects on your CV? What did you learn from them?
  • How well do you understand the technologies or domains in which you’ve worked?

Ahead of this interview we recommend that you refresh your memory of your CV and any other material you provided to us, such as LinkedIn or Github pages.

This interview is also a great opportunity for you to ask questions and build your understanding of CarbonChain and the role.

🤓 Technical task

After the phone screen, the next stage is a technical task. This might be a take-home or a live exercise depending upon the role.

We’ll typically ask you to complete the test in the week after the phone screen, but we appreciate that everybody has their own constraints. We’re happy to fit in around your timelines. We expect it to take 2-5 hours.

In all cases, the kind of things we’re looking for are:

  • Does the work achieve the outcome we were looking for?
  • Can you clearly communicate what you’ve done? When challenged, can you defend choices you’ve made?
  • What’s it like to work with you? How do you take feedback and think things through with your potential colleagues?
  • How well do you understand the context of the task you’re doing? How much have you figured out about the domain?

For many roles, we’ll address these questions in a separate review session, also online. In those cases, we’ll ask you to expand upon the solution you submitted, to get a feel for what it’s like to pair program with you.

🤝 In-person panel

If you get to the final round, congratulations! You’ll be invited to an in-person round of interviews at our London office (36 Gloucester Avenue, Primrose Hill).

This round typically consists of 3 or 4 interviews (over the course of about half a day). You'll meet our co-founders (Adam and Roheet) and one or two team members with whom you would work a lot if you got the job.

In this round you can expect more focus on whether you’re a strong cultural fit with our values (see above). We’ll also try and get a sense for how you’d fit into the team, what your aspirations are, and how well you’d interact with people in different roles within the organization.

We’ll try and schedule the interview so you can either join us for lunch (let us know if you have preferences - we’ll order veggie by default) or a pint at the pub across the road.

Next steps

We do our best to meet and evaluate the outcome of the full interview process within 24 hours. Everybody who has been involved in the interview process will contribute their thoughts on the strengths and weaknesses we observed during the process.

Hopefully we’ll then be in touch to extend an offer 🙌🏼

Once you’ve accepted an offer

We’ll ask you to provide 3 references, at least one of which is a direct manager.

We’ll give each of these a 10 minute call to get a better understanding of what you’re like to work with, and how we can set you up for success at CarbonChain.
