Rakuten Software Engineer interview typically runs 3-4 rounds: recruiter screen, online coding assessment, technical interview(s), and behavioral/final round. Timeline is about 1-2 weeks and the process is structured but often heavy on fit and communication.

Our candidates report that Rakuten is less interested in dazzling algorithms than in whether you can stay precise under pressure and explain your engineering choices cleanly. Across experiences, the technical questions were often described as LeetCode easy-to-medium, but the catch was in the details: hashmaps, binary search, segment trees, OOP, database design, networking, and even HTTP version differences. That pattern tells us the bar is not about novelty; it’s about solid fundamentals applied without hand-waving. When candidates rushed, the problems became trickier than they looked on paper.
A recurring theme is how much weight Rakuten places on motivation and work history. Multiple candidates were asked why they wanted to join Rakuten, why they left prior companies, and how they handled team disagreements or pressure. We’ve also seen questions about Japanese work culture, language learning, and general attitude, which suggests the company is screening for stability, communication, and cultural alignment as much as technical ability. Even in rounds that included system design or infrastructure topics like load balancing, Linux, cloud, and deployment, the conversation often stayed grounded in the candidate’s own projects and decisions.
The non-obvious part is that the process can feel broader than a typical software engineering interview, especially for candidates expecting deep coding throughout. Our candidates report that Rakuten may pivot from coding to behavioral to project-specific discussion with little warning, so the strongest performers are the ones who can connect basics to real systems and speak confidently about past work without overcomplicating it.

Real interview reports from people who went through the Rakuten process.
I went through four rounds: screening, system design, a core technical round, and a fitment round. The screening round checked whether my background matched the role. The system design round focused on my current project. The core technical round focused on Java fundamentals, and the final fitment round was mostly behavioral.
Questions asked: The online/core screening covered basic data structures, networking protocols such as differences between HTTP versions, and standard library definitions.
In the technical interview, I was asked to write a character frequency counter and discuss time and space complexity. There was also an anagram variant where I had to rearrange characters so that no two identical characters were adjacent, or handle the case where no valid rearrangement was possible.
The Java discussion covered OOP concepts such as polymorphism, abstraction, and encapsulation; Java 17 features including sealed classes, pattern matching, and records; and Stream API usage for filtering and transforming collections. The behavioral portion covered motivation for joining the company, engineering disagreements in an agile team, and adaptability to a global work culture.

Synthesized from candidate reports. Individual experiences may vary.
An in-house recruiter or HR contact reaches out first to confirm your background, motivation, and basic fit for the role. In some cases this is a short screening call before the technical rounds begin.
Candidates complete a home or online coding test, often on Codility or an OJ-style platform. The problems are typically LeetCode easy-to-medium or medium-level, with topics like hashmaps, binary search, strings, segment trees, and other core DSA fundamentals.
The first technical round usually covers your projects, current experience, and basic problem solving, along with coding or DSA questions. Depending on the team, it may also include fundamentals such as OOP, databases, HTTP basics, Python libraries, networking, Linux, cloud, DevOps, or automation.
A hiring manager or two-interviewer panel goes deeper into technical discussion and how you think through design or implementation. Some candidates were asked about system design, load balancing, ledger systems, database design, and how they would explain past projects under pressure.
The final conversation is often more behavioral than technical and focuses on motivation, teamwork, communication, and reasons for leaving previous companies. Interviewers also ask about why you want to join Rakuten, how you handle disagreements, and whether you fit the company and team culture.
