9 Boston Dynamics Software Engineer Intern Interview Questions (2026)
Boston Dynamics' SWE intern loop in 2026 is a recruiter screen, an OA, and a 2-3 round virtual interview. The intern program is small and competitive, with strong preference for students with robotics, controls, or real-time systems coursework. Conversion to new-grad is the typical path for top performers.

Loop overview
Intern flow: recruiter → OA (2 problems, ~90 minutes) → two to three 45-minute virtual rounds. Most reports show one or two coding rounds plus a behavioral and an optional domain conversation. Timeline is typically 4-6 weeks. Internships are based in Waltham, MA.
Behavioral (3)
Walk me through a project where you worked with hardware or robotics.
Frequently askedOutline
Pick a project — robotics class, FRC team, Arduino, drones. Walk through what you built, your role, what worked, what failed. Be ready for follow-up on the software-hardware interface. If you have no hardware experience, pick a systems-adjacent project (operating systems, embedded coursework).
Why do you want to intern at Boston Dynamics?
Frequently askedOutline
Reference specific interest in robotics, real-time systems, or specific products (Spot, Stretch, Atlas). Mention robotics coursework, hardware projects, or papers you have read. Generic 'I love robots' is weak.
Tell me about a time you debugged something hard.
Frequently askedOutline
STAR. Pick a real bug with a non-obvious root cause. Walk through methodology: reproduce, narrow down, hypothesize, verify. Robotics bugs are often subtle — timing, sensor noise, coordinate-frame mistakes.
Coding (LeetCode patterns) (5)
Given a 2D grid representing a robot's environment, find the shortest path from start to goal avoiding obstacles.
Frequently askedOutline
BFS for unweighted. A* with Manhattan heuristic for performance. Walk through the priority queue, visited set, parent pointers for path reconstruction. O(rows × cols) time and space. Discuss the heuristic — Manhattan distance is admissible for 4-connectivity grids.
Implement a function that returns the depth of a binary tree.
Frequently askedOutline
Recursion: depth(node) = 1 + max(depth(left), depth(right)); base case null returns 0. O(N) time, O(H) space. Walk through iterative BFS alternative — count levels.
Implement a function that returns whether parentheses in a string are balanced.
Frequently askedOutline
Stack-based. Push opening, pop and match on closing. Return true only if stack is empty at end. Handle (), [], {}. O(N) time, O(N) space. Edge cases: empty string, unbalanced closing first.
Given a list of (x, y) points, find the two closest points.
Frequently askedOutline
Brute force: O(N^2). Divide-and-conquer: O(N log N). Walk through the divide step (sort by x, recurse left and right), then the strip check (only need to check up to 6 next points within strip).
Implement a function that computes the dot product of two vectors.
Occasionally askedOutline
Single pass. Sum of element-wise products. O(N) time, O(1) space. Walk through edge cases: empty vectors, mismatched lengths (raise or return 0). Discuss SIMD for performance on long vectors.
Technical (1)
Explain the difference between a stack and a heap in C++.
Frequently askedOutline
Stack: LIFO, automatic allocation tied to scope, fast, limited size (~1MB default). Heap: dynamic allocation via new/malloc, manual free or smart pointers, slower, much larger. Local variables on stack, objects from new on heap. Discuss stack overflow vs heap fragmentation.
Boston Dynamics interview tips
- C++ proficiency is the single highest-ROI prep. Brush up on smart pointers, references, RAII.
- Graph and grid problems come up often. Practice BFS, DFS, A* in C++.
- Have one strong robotics or hardware project ready. Even a class project counts.
- The OA gates everything. Practice timed C++ problems with edge cases.
- Intern conversion at Boston Dynamics is strong for high performers. Treat the internship as a 12-week extended interview.
Frequently asked questions
How long is Boston Dynamics' SWE intern interview process in 2026?
Most reports show 4-6 weeks from OA to offer.
How many rounds are in Boston Dynamics' SWE intern onsite?
Two to three virtual rounds in 2026, typically 45 minutes each. One or two coding plus a behavioral and an optional domain conversation.
Does Boston Dynamics hire international SWE interns?
Yes, Boston Dynamics has sponsored F-1 OPT/CPT for interns. Confirm with your recruiter for 2026.
Do I need robotics coursework to intern at Boston Dynamics?
Not strictly required, but it strongly helps. A robotics course or hardware project on the resume signals genuine interest. Without it, prepare on real-time systems and control fundamentals.
What language should I use for Boston Dynamics intern interviews?
C++ if you know it. Python is accepted for coding rounds. C++ fundamentals appear in the technical conversation regardless.
