Mambu Interview Questions
& Process

The interview process involved a 30-minute initial chat with HR, followed by a 1-hour meeting with the hiring manager. Then there was a 3-hour take-home coding assignment (Go), and finally, a 1-hour technical discussion. The process moved to the last stage even though there was a clear disconnect in how questions were asked and how answers were judged. Some technical questions lacked sufficient detail. When candidates tried to clarify assumptions or constraints, it was viewed negatively instead of being used to get on the same page about the problem. If answers didn't meet unstated expectations, the conversation turned argumentative instead of being helpful. The evaluation criteria seemed to prioritize experience with fintech integration patterns over critical thinking, problem definition, or open discussion of trade-offs. Candidates without extensive fintech integration background should make sure to clarify expectations upfront.

I had a 30-minute phone call with the recruiter. We mostly talked about my background and resume, and why I'm interested in this role. They asked about my past jobs, why I'm looking for something new, and what I want in my next position. The recruiter also gave a quick rundown of the company, the team, and what to expect next in the interview process. It was a chill and informative chat, and the recruiter was nice, professional, and clear on what happens next.

So I interviewed for a role at Mambu Amsterdam. The recruiter call was pretty good, they told me about the company, the culture and the role. That was a good start. Then I had two more interviews where we talked about the role and my skills. That made me more interested. But the last interview was not good. I talked to someone who wasn't even working there yet, and they didn't know anything about the role, they described a totally different job. After that, it took forever to get any feedback, I had to ask like multiple times. Finally, I found out they had already hired someone. The beginning was good, but the end was not. They should make sure everyone interviewing knows about the role and communicate better.

Got contacted by a recruiter on LinkedIn because my profile was a good fit. Had a couple back and forths with the recruiter and they scheduled an interview fast. The recruiter did miss our first chat because of a family emergency but let me know right away and our second try went great! She said she'd recommend me for a management interview. Then I talked with my now manager, who described the role really well and asked a lot of questions to see if I was a good fit. I got to ask questions too and it went well, leading to the next step. The last part was preparing and giving a presentation like I work at Mambu to my potential teammates. It was tough to prep and made me nervous, but I just presented a project like I do at my current job. The team asked good questions about my process and background. They were welcoming and put me at ease, and I got a feel for the team beforehand. I got the offer by 8/4! The recruiter called me and I accepted via email. I was kept in the loop the whole time, and recruitment was responsive and helpful, even giving guidance on the presentation.
