Recruitment FAQ

What does the typical hiring process look like, and how long does it take?

Our typical hiring process consists of 4 stages, designed to assess both key technical and soft skills while ensuring team fit. We aim to complete the process within 1–2 weeks, with clear communication and feedback throughout. It begins with an intro call to get to know each other, followed by two technical stages that include deeper discussions about your experience, motivation, and development paths, as well as a live coding session. The final step is a culture-fit conversation with our CEO and CTO.

How should I prepare for the recruitment process?

We care about how you think, communicate, and solve real problems. That’s why areas below might come in handy when you are preparing for an interview:
- Projects & technologies you’ve worked with, including the challenges you faced and how you solved them
- Your reasoning and decision-making, as well as being ready to walk us through your choices
- Preparing a few questions for us - it’s a two-way conversation.

Can I choose the type of contract that works best for me?

Yes, you can choose between B2B cooperation or a common employment contract. Both options come with the same perks and benefits. If you’re unsure which form of collaboration is best for you, our team is happy to provide guidance and answer any questions.

What language will we speak during the recruitment process?

English is our main language - both within the team and with stakeholders. That’s why most of our recruitment meetings are conducted in English. You don’t need to be perfect, but you should feel comfortable discussing technical ideas and collaborating in that language.

What project will I work on?

Rather than hiring for a single project, we focus on building long-term collaboration. When forming or expanding a team, we consider your personal preferences, skills, and career goals to ensure that every step contributes to your growth.

Do you offer remote, hybrid, or on-site work options?

We are a remote-friendly organization, and you can choose to work from one of our offices in Kraków or Berlin, or from home if that suits you better. However, for certain roles, we might be looking for people living in the same region.

I have a question that’s not covered here.
