10 Boston Dynamics Software Engineer (New Grad) Interview Questions (2026)
Boston Dynamics' new-grad SWE loop in 2026 is a recruiter screen, an OA, a phone screen, and a 4-round virtual onsite. Backend is C++ and Rust with Python for tooling. The company designs and builds Spot, Stretch, and Atlas — robots with real mechanical hardware — so new-grads with robotics, controls, or real-time systems coursework get a strong signal advantage.

Loop overview
New-grad candidates report a 5-8 week timeline in 2026. Online assessment (2 problems, ~90 minutes, often C++ flavored), then a 45-minute phone screen. Onsite is four 45-minute rounds: two coding rounds, one robotics-fundamentals or systems round, one behavioral. Most engineering is in Waltham, MA. Boston Dynamics is owned by Hyundai but operates independently.
Behavioral (3)
Why Boston Dynamics?
Frequently askedOutline
Tie to interest in robotics, real-time systems, or specific products (Spot for industrial inspection, Stretch for warehouse logistics, Atlas for research). Mentioning a robotics course, FRC/FTC participation, or any hands-on robotics project lands well. Generic 'I love robots' is weaker than 'I built a hexapod for my robotics course and learned X'.
Tell me about a time you worked on something with physical hardware.
Frequently askedOutline
STAR. Robotics is hardware + software. Pick a real moment — robotics class, FRC team, Arduino project. Discuss how software-hardware integration changed your approach. Be specific about a bug or issue that only manifested with real hardware.
Tell me about a time you had to optimize something for performance.
Frequently askedOutline
STAR. Robotics has tight real-time budgets. Pick a project where you profiled, identified a bottleneck, and made a change that mattered. Discuss the measurement methodology — guesses do not count.
Coding (LeetCode patterns) (3)
Given a list of waypoints, return the shortest path visiting all of them (Traveling Salesman).
Frequently askedOutline
Exact DP solution: Held-Karp, O(N^2 × 2^N) — only feasible for N <= ~20. Discuss approximations: nearest-neighbor (greedy, no guarantee), 2-opt (local search), Christofides for metric TSP (1.5x optimal). Walk through the DP formulation. For robots with limited waypoints (e.g. inspection tour), exact is often OK.
Implement a function that performs a topological sort on a DAG.
Frequently askedOutline
Two approaches: (a) Kahn's algorithm — repeatedly pull nodes with in-degree 0; (b) DFS-based — post-order traversal reversed. Walk through both. O(V + E) time. Discuss cycle detection — if any node is left in the in-degree map at the end (Kahn) or a back edge is found (DFS), the graph has a cycle.
Implement a function that checks whether two rectangles overlap.
Occasionally askedOutline
Given (x1, y1, x2, y2) for each: they overlap iff NOT (rect1.right <= rect2.left OR rect2.right <= rect1.left OR rect1.top <= rect2.bottom OR rect2.top <= rect1.bottom). O(1). Walk through carefully — the inverted-condition logic is where candidates trip up.
Technical (3)
Implement a function that, given a 3D point cloud, finds the ground plane.
Frequently askedOutline
RANSAC. Repeatedly: sample 3 points, fit a plane, count inliers within a tolerance. Best plane wins. O(N × iterations). Walk through the math: 3 points define a plane (cross product for normal). Discuss tolerance — depends on sensor noise. Mention alternatives: M-estimators, least-squares with outlier rejection.
Explain what move semantics in C++11+ accomplish.
Frequently askedOutline
Move semantics let you transfer ownership of resources from one object to another without copying. Useful for large containers, unique_ptr, file handles. Walk through rvalue references (T&&), std::move (cast to rvalue), move constructors, move assignment. Discuss when the compiler elides copies (RVO, NRVO). Pitfall: 'using a moved-from object' is a common bug.
Given a stream of joint-angle measurements, detect when the robot is in a specific pose.
Frequently askedOutline
Compare current joint angles against the target pose, compute distance (Euclidean or per-joint with weights). Threshold to detect. Walk through hysteresis to avoid flapping (enter at threshold T1, exit at threshold T2 > T1). Discuss handling noise — temporal smoothing.
System / object-oriented design (1)
How would you design a real-time control loop running at 1 kHz?
Frequently askedOutline
Real-time priorities. Allocate memory upfront (no malloc in the loop). Avoid blocking I/O. Use a real-time OS or Linux PREEMPT_RT. Walk through the loop: read sensors → compute control → command actuators. Discuss timing budget (1ms per cycle), what happens on overrun (skip vs catch up). Cite practical constraints: lock-free queues for IPC, careful with caches.
Boston Dynamics interview tips
- C++ is the primary language. Brush up on smart pointers, move semantics, RAII. Rust knowledge is a bonus signal.
- Real-time systems thinking is a discriminator. If you have not worked with real-time OS or robotics, read a primer on PREEMPT_RT and timing budgets.
- Geometric algorithms (RANSAC, plane fitting, transformations) come up. Practice them in C++.
- Robotics or hardware projects on the resume carry significant weight. Even a course project counts.
- Compensation per Levels.fyi 2026 is solid Boston-area new-grad. Hyundai equity grants for senior roles; new-grads typically get cash bonuses.
Frequently asked questions
How long is Boston Dynamics' SWE new-grad interview process in 2026?
Most reports show 5-8 weeks from recruiter outreach to offer.
Do I need to know C++ to interview at Boston Dynamics?
Strongly yes. C++ fundamentals (move semantics, smart pointers, RAII) appear in technical conversation. Python is accepted for coding rounds; C++ for the systems-flavored ones.
Does Boston Dynamics ask system design for new-grad SWE?
Yes. The systems round often covers real-time control loops, IPC, or sensor pipelines. Less abstract distributed-systems than typical web companies.
Do I need robotics experience to interview at Boston Dynamics?
Not strictly required, but it strongly helps. A robotics course, hardware project, or FRC/FTC participation signals genuine interest. Without it, prepare deeply on real-time systems and control theory basics.
Does Boston Dynamics sponsor visas for new-grad SWE?
Boston Dynamics has sponsored H-1B and OPT in past US cycles. Confirm with your recruiter for 2026.
