Applied for a Senior Software Engineer (Java) at Mollie in July 2022. Initially had a screening call with a recruiter(Neil) where he described the hiring process at Mollie in a nutshell. Neil was very friendly, provided a good level of support, and transferred all the feedback he had on each stage. As for the interview phases – there were 4 of them: hackerrank test, code review session, system design session, and cultural fit. Hackerrank(90 minutes): 3 questions that could be answered with a programming language you like (JS, C#, Java 8/17). Nothing really difficult – not a dumb leetcode questions but more like the things you might face from day to day on your work Code review(45 minutes): they will give you a gist with a code where you will have to identify all the problems that code has and also offer improvements (just in words, you can't actually provide any code). Cultural fit(60 minutes): nothing really fancy, just a friendly talk about different kinds of situations you faced/might face. System design(75 minutes): you will be given general statements of how the system you are designing should behave. The task is to ask as many questions as possible, draw the diagrams, describe a database schema, and discuss potential performance issues you might have. All went well (maybe except system design interview) and it end up giving me an offer for a Middle PHP engineer position, which was pretty awkward to hear and accept. Overall that was a positive experience and all the people I talked to were really nice and positive. I think that would be a good experience working at Mollie if they could give a position you've applied to but not offer a not relevant to your experience opportunity.
