SambaNova's Interview Process (2026)

Blog / SambaNova's Interview Process (2026)
SambaNova Interview Process
The SambaNova software engineer interview process is technically demanding, with a strong focus on systems programming, performance optimization, and AI infrastructure. Most candidates report a process spanning 4 to 6 stages, though the exact structure can vary by seniority and team.
  • Recruiter Screen: Typically a 30-minute call covering your background, interest in AI hardware and software, and general fit. Expect a conversation about salary expectations and next steps.
  • Technical Phone Screen(s): Usually one to two rounds, each around 60 minutes. New grad candidates often face two screens covering DSA and basic systems concepts, while senior candidates typically go through a single deep-dive into a specific technical area like C++ optimization.
  • Virtual Onsite: A full-day loop conducted over video, generally consisting of four to five rounds. This usually includes coding, systems and architecture, a project deep dive, and a behavioral round with a hiring manager.
To prepare effectively, break your study plan into these key areas that reflect what SambaNova interviewers actually test:
  • Data Structures & Algorithms (DSA): LeetCode-style coding questions at medium to hard difficulty, with an emphasis on correctness, edge cases, and efficiency.
  • System Design: Designing high-throughput, cost-efficient systems with a focus on how software interacts with hardware.
  • Code Review & Optimization: A SambaNova-specific format where you are given existing C++ or Python code and asked to identify performance bottlenecks and improvements.
  • Behavioral: Values-driven questions assessing how you operate in a fast-paced, talent-first environment.
1. Data Structures & Algorithms (DSA)SambaNova coding rounds focus on medium to hard difficulty problems, but the bar is not just a working solution. Interviewers look for proper error handling, input validation, and code that is written with performance in mind from the start.Common patterns reported by recent candidates include sliding window, tree serialization and deserialization, and hash map edge cases. Spending time on sliding window questions and tree problems will put you in a strong position for these rounds.For a focused starting point, work through our top 100 DSA questions to cover the most frequently tested patterns before going deeper on any one topic.
2. System DesignSambaNova system design questions are grounded in real AI infrastructure problems. You might be asked to design a rate limiter for an AI API, architect a distributed caching system for model weights, or explain how you would build a high-throughput inference service.A strong trend in 2025 and 2026 is explicit focus on cost-efficiency and power constraints. Answers that default to adding more servers are considered weak; interviewers want to hear about right-sizing, observability, and operational tradeoffs. Brush up on system design core concepts and caching fundamentals to build a solid foundation.Practice drawing out your architectures before the interview. Our System Design Whiteboard lets you work through designs interactively, which is a good way to simulate the real thing.
3. Code Review & OptimizationThis is one of the most distinctive parts of the SambaNova interview. Rather than giving you a blank coding problem, interviewers often present a snippet of existing C++ or Python code and ask you to identify optimization bottlenecks and explain how to make it run faster on custom hardware.To prepare, go beyond syntax and get comfortable reasoning about SIMD, multi-threading, memory alignment, and cache locality for large-scale operations. Reviewing operating systems concepts will help ground your understanding of how software maps to hardware execution.It also pays to understand the basics of SambaNova's Reconfigurable Dataflow Unit (RDU) and how it differs from a GPU. Candidates who can speak to the hardware context during a code review are consistently flagged as strong fits.
4. BehavioralBehavioral questions at SambaNova are framed around three core values: Integrity, Innovation, and Excellence. Expect questions that probe how you handle ambiguity, push for quality under pressure, and collaborate in a fast-moving environment.Structure your answers clearly and concisely. Using the STAR principle keeps your responses focused and easy to follow without rambling. Our Behavioral Playbook also covers common patterns and how to tailor them for company-specific values.
ConclusionSambaNova's interview is technical at every layer, so the candidates who stand out are those who can think about performance and efficiency at the systems level, not just write code that works. Start with a structured plan and follow our SambaNova Interview Roadmap for a step-by-step path through every stage of the process.
