Candidates describe a Coolblue Software Engineer process that begins with a recruiter conversation and moves into how you think about engineering practice. One candidate reports a second round with a technical team member where the discussion covered software development methodologies and testing strategy, including test-driven development. If you are preparing, be ready to explain how you test, why, and where you stand on process.
The take-home assignment appears in both detailed Software Engineer reports. One candidate describes average-difficulty coding problems alongside design pattern questions. They then had a live coding interview built on their own submission, where they had to explain their design choices. The other candidate reports a take-home followed by a final technical interview. Write the solution as you would for a real team, and rehearse walking through your decisions aloud.
A separate C# Developer candidate in Rotterdam reports an early recruiter call that focused on salary expectations and automated testing experience, with Selenium and Playwright named. That is a different role, so treat it as a hint rather than a template. Know your salary expectations and be ready to rate your test automation experience honestly.
Timing and outcomes varied. One candidate describes a process of over three months, including a dedicated cultural round after an offer letter was signed. The other describes gaps of almost two weeks between rounds. Neither candidate in the Software Engineer reports received a working offer. One had a contract canceled before the start date, and the other did not advance. Keep applications to other teams transparent, and ask the recruiter how Coolblue handles them.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report starting with an online meeting with a recruiter, who walks through the role and asks about your background. One candidate with a positive screen then moved to a managerial round. Expect questions on experience, and possibly salary expectations, so prepare numbers in advance.
One candidate reports a second round with a technical team member alongside the recruiter. It covered software development methodologies and principles, plus testing strategy and test-driven development. Prepare to explain your own approach to code quality and process, not just to write syntax.
Both detailed Software Engineer reports mention a take-home task. One describes average-difficulty problems and design pattern questions. Candidates may be asked to defend their choices later, so keep your solution clean, tested and easy to explain.
One candidate reports a live coding interview based directly on their take-home submission, with discussion of design choices. Another expected the final technical round to go deeper into the assignment or into coding problems. Be ready to extend your solution and justify tradeoffs.
One candidate reports a dedicated cultural round that came after an offer letter was signed, along with conversations with a relocation specialist. This may not apply to every candidate. Prepare behavioral examples, and clarify with the recruiter how multiple applications are handled.
