Motmans & Partners AI Research Scientist interview typically runs 4-8 rounds: recruiter screen, coding, research presentation, research interviews, system design, and behavioral. The process usually takes about 2 months and is notably research-heavy with a strong coding component.

We've seen a clear pattern in our candidates' experiences at Motmans & Partners: this is not a pure research interview, even for an AI Research Scientist. Multiple candidates reported a LeetCode-style coding bar that showed up early and stayed present throughout the process, alongside research conversations that dug into Ph.D. work, papers, and future research direction. The company seems to care less about polished buzzwords and more about whether you can move comfortably between theory and implementation without losing rigor.
A recurring theme is how much weight they place on defending your technical choices. The research talk was described as a real test of whether candidates could communicate to other researchers, not just present slides. In the technical discussions, interviewers asked about statistical estimators, VAEs, batch normalization, and even ML system design prompts like harmful-content detection or location ranking, which suggests they want people who can reason from first principles and connect that reasoning to product constraints. Our candidates also noted that the interviewers were often highly technical, with strong statistics backgrounds, so shallow ML familiarity tends to stand out quickly.
The non-obvious make-or-break factor here is breadth. Candidates who expected a standard research chat were surprised by the amount of coding and system design, while those who over-indexed on algorithms without enough research depth also struggled. The strongest signal appears to be a candidate who can be credible in both worlds: someone who can write clean code under pressure, explain research decisions clearly, and show they understand how an ML idea would actually ship in a product setting.

Real interview reports from people who went through the Motmans & Partners process.
The hardest part for me was realizing this wasn’t just a standard research chat. The process started with a recruiter screen, then moved into a fairly long loop that included several 1:1 interviews, a coding interview done as pair coding, and a research talk that I had to prepare and present in front of researchers. On top of that, there was also a system design interview, two coding interviews, and a behavioral round, so the whole thing stretched out to about two months. The recruiter and HR side felt very responsive, and the hiring manager I spoke with was polite and friendly, which made the process feel professional even when the questions got more demanding.
Most of the conversation in the hiring manager round was about my research interests and past experience, and I also got a straightforward behavioral question about my strengths and weakness. The research talk was the most distinctive part because it wasn’t just a presentation exercise; it was clearly meant to test how I communicate research to other researchers and defend my choices. The coding rounds were more traditional and focused on solving various coding questions under interview conditions, while the system design round added another layer beyond pure research depth. I ended up getting rejected a few days after the hiring manager conversation, so the outcome was disappointing, but the process itself was well organized. My main takeaway is to prepare both a polished research presentation and enough coding/system design practice to handle a mixed research-plus-engineering loop.
Prep tip from this candidate
Prepare a research talk you can present clearly to researchers, and don’t treat the loop as research-only — there were also pair coding, multiple coding rounds, and a system design interview. Be ready to explain your research interests and why you want the role, since that came up directly in the hiring manager conversation.

Synthesized from candidate reports. Individual experiences may vary.
The process typically begins with a recruiter or HR screen. Candidates described the recruiting team as responsive, though one experience noted communication could feel noisy because multiple recruiters were involved.
The first technical round is usually a live coding interview over Zoom. It is often LeetCode-style and can include two medium-difficulty problems, with some candidates saying it felt harder than expected and not always closely tied to the research role.
Candidates are asked to prepare and present a research talk to researchers or the broader team. This stage is meant to test how well you communicate research, defend your choices, and explain your work to a technical audience.
This round focuses on your past and current research, Ph.D. work, papers, and future research direction. Interviewers often ask detailed follow-ups on literature, research vision, and the reasoning behind your projects.
Candidates reported a mix of ML fundamentals, statistics, and applied design questions. Topics included evaluating statistical estimators, VAEs, batch normalization, and designing systems such as harmful-post detection or location ranking/personalization.
A behavioral or hiring manager conversation typically closes out the loop. The discussion often covers strengths and weaknesses, research interests, and past experience, and candidates described the tone as polite, friendly, and professional.
