What it’s like to be a Chocorian

You will join a company filled with smart, humble and hard-working people. We are a start-up where people put the team first, deeply trust each other, take ownership and truly understand what they are working for day by day.

You will join a group of people from all around the world who share their experiences and contribute in their areas of expertise and learn from each other.

You will join a passionate team that shares the same values and vision, a circle of friends that not only works hard but also laughs with- and cheers for each other.

With that said, it is absolutely crucial to find people who share this with us and who deeply identify themselves with the values of a Chocorian.

We invite you to take part in the following selection process:

  1. Introduction call: a Tech Recruiter will tell you more about Choco, our Tech Org and get to know your work, background, interests and you as a person better.

  2. Technical interview: our Backend Chapter Lead will have a technical deep dive with you. No coding, no whiteboard here. We want to map your previous experience, NodeJS engineering fundamentals, knowledge of architectures, TypeScript and testing background.

  3. Tech challenge at home: now is the time to show us your coding skills via a task from the comfort of your home. Our tech challenge models a simple web app and it takes about 3-4 hours to complete.

  4. Product Demo: present your task solution to our Team Lead and Product Manager like a demo. They will check your fit to the team, how you collaborate with the non-tech side of the organization and your way of thinking about the product.

  5. Cultural interview: we will have a chat with you about our culture and checks what can be your non-technical contribution to Choco.

OFFER: your interviewers will make a decision together regarding your offer.

A stellar onboarding and the smartest team in the foodspace will be waiting for you!
