What happens after you apply

Send us your CV in English. If your experience looks like a good match, we’ll get in touch and keep the conversation going. You can expect three rounds: first, a chat with HR and the hiring manager to get to know each other and talk about the role; then, a technical interview with the Product Owner and members of the team; and finally, a short call with the CDC manager.

At least one of these conversations will be in person, because even in the age of AI, we still prefer meeting people over pixels.
