The interview process was well-structured and consisted of several stages. It started with an initial call with the HR team, followed by a coding test on HackerRank. If the test was passed successfully, the next steps involved two technical interviews: the first focused on reviewing a pull request (PR), and the second on System Design. If the technical stages were cleared, the process continued with two additional interviews—one assessing alignment with company culture and another with the prospective manager. These non-technical interviews included a significant number of behavioral and situational questions aimed at evaluating how candidates approach different business scenarios and challenges.

Applying for a job at Mollie is a long and demanding process. It starts with an initial conversation with a recruiter, which is fairly general. Next, there is an online technical assessment involving coding and SQL challenges. If successful, you move on to a "code review" discussion with two engineers, followed by a "system design" interview with another pair of engineers. The final stages include a meeting with the hiring manager and a "company values" interview (which I didn't reach). While I understand that thorough hiring processes help companies find the right candidates, Mollie's approach feels excessive and inefficient. The process requires significant time and effort, and unfortunately, my experience ended with a rejection. Normally, I take rejections in stride, but this one left a bitter taste. The reason? Feedback from one of the interviewers in the "system design" round. The principal engineer leading that session lacked the ability to guide the discussion effectively, failed to ask relevant questions, and then provided feedback based on topics that were never even addressed. It was a frustrating and disappointing experience. I hope Mollie re-evaluates its hiring approach to make it more structured, fair, and respectful of candidates' time. Good luck to those applying.

The interview included an introduction interview, an offline coding test + questions, a live coding session, a live system design session, and a live leadership principles interview based on the company values. After the scrutiny process, if you pass the tests, you are expected to have fit interviews with different teams until a good match is found. There is a lot of flexibility in retaking some steps of the process depending on the specific role (full stack eng, backend eng, platform eng) and ensuring a good fit is found.
