Rakuten Software Engineer candidates report a process that can combine a coding assessment with conversations about projects, motivation, and team fit. Across several accounts, coding ranged from basic data-structures questions to medium-difficulty problems involving arrays, hashmaps, binary search, heaps, and sorting. Some candidates encountered an online assessment, while others described live or interview-based coding. One candidate also reported follow-up changes to a problem. Practice explaining your approach clearly, adapting when requirements change, and checking your solution before moving on.
System design and practical engineering discussion can also matter. One candidate described a hiring-manager round that leaned toward system design. Other reports mention project walkthroughs, general programming fundamentals, networking concepts such as the difference between HTTP 1.0 and HTTP 1.1, Python libraries, and practical technical knowledge. Prepare to explain past projects, the decisions you made, and how your technical knowledge applies in realistic engineering situations.
Behavioral conversations covered motivation for Rakuten, teamwork, career moves, past experience, and work style. Reports differ substantially in technical depth: some candidates encountered multiple technical discussions, while others found later conversations primarily behavioral or focused on department context. The evidence does not establish one fixed interview format. A balanced preparation plan should therefore include coding practice at an easy-to-medium level, a clear walkthrough of relevant projects, review of core engineering fundamentals, and concise examples showing collaboration and problem solving.

Real interview reports from people who went through the Rakuten process.
The coding portion was the part that stood out most: the first two rounds had medium-difficulty problems involving heaps, arrays, and sorting. They were practical LeetCode-style questions, sometimes with follow-ups and a bit of math, so I had to explain my approach and adjust it as the problem changed. The last round shifted away from pure algorithms and focused on practical knowledge.
In my case, there was no HR interview. The overall process felt geared toward checking whether I could handle standard coding work and apply fundamentals in a realistic setting rather than only recite theory. I accepted the offer, although I was told that full-time conversion was not guaranteed and the conversion rate could be low. My main advice is to be comfortable solving medium array, sorting, and heap problems under follow-up questions, then be ready to discuss how you would apply your knowledge in practice rather than treating every round like a standalone algorithm exercise.
Prep tip from this candidate
Practice medium-difficulty heap, array, and sorting problems with follow-up variations, and prepare to explain practical engineering knowledge in a final round that is less algorithm-focused.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an initial coding component in several paths. Topics included arrays, hashmaps, binary search, heaps, sorting, strings, basic data structures, and complexity discussion; difficulty ranged from basic to medium depending on the account. Practice explaining an approach, handling a follow-up, and checking edge cases.
Reported technical conversations varied. Candidates described project walkthroughs, Java and OOP fundamentals, networking concepts, practical engineering knowledge, and system-design discussion. One candidate designed a scalable cashback application with microservices, APIs, caching, database choices, reliability, and performance considerations.
Candidates report questions about motivation for Rakuten, teamwork, conflicts, career moves, ownership, stakeholder collaboration, and work style. Prepare concise examples with your role, decision-making, outcome, and what you learned; some accounts describe this emphasis as substantial.
Several candidates explicitly reported three or four rounds, though the final conversation differed by candidate. It may focus on behavioral fit, practical knowledge, department context, or a remaining technical topic. Use it to communicate how your experience fits the role and to ask informed team questions.
