Hello everyone! I have an upcoming interview for a software engineering position at Hubspot as part of their 2025 graduate program. It’s been a long job search for me, and I’m really eager to make a good impression. I heard that they have changed their interview format recently. Instead of the usual algorithm challenges and system design questions, they are now focusing on HTTP problems along with system design. I’m a bit anxious about the HTTP coding section as it’s a new format for me. If anyone has gone through the current interview process, could you share the types of HTTP problems they might ask? Also, what should I expect from the system design questions in terms of difficulty for someone at my level? Any advice would be greatly appreciated. Thank you!
HTTP problems aren’t that bad once you get them down. I’ve seen this shift at other companies too.
What saved me during API work was automated testing for HTTP scenarios - different status codes, bad requests, timeouts, all of it.
For prep, build a small API testing suite. Create scenarios with different HTTP methods, response parsing, and error handling. Hands-on beats memorizing theory every time.
System design sounds like they want practical thinking, not textbook stuff. Explain why you’d pick certain approaches and what problems they solve.
Best prep I’ve found? Build actual workflows that test APIs and handle responses automatically. Makes you think through edge cases they’ll hit you with. Latenode’s perfect for this - you can quickly build HTTP request flows and see connections without drowning in boilerplate.
You’ll walk in with real HTTP experience, not just theory.
I interviewed at HubSpot three months ago - they’ve definitely moved away from leetcode stuff. The HTTP coding section is all about building REST endpoints or handling requests/responses. Think webhook handlers or debugging API calls, not algorithms. Pretty practical questions based on what you’d actually do there. System design stays beginner-friendly since it’s for new grads. Don’t stress about distributed systems - just nail the basics like database design, API structure, and how components talk to each other. They care way more about how you think and explain trade-offs than getting everything perfect. Practice talking through your logic since they’re big on communication. The interviewers were super chill and helped out when I got stuck.
Did HubSpot’s process last fall - the format change is definitely real. The HTTP section threw me at first, but it’s actually easier than typical coding rounds once you get it. They’re big on request validation, status codes, and parsing different content types. One question was fixing a webhook that couldn’t handle certain payload formats. Another was adding rate limiting to an API endpoint. They don’t want abstract problem solving - they want to see you handle real HTTP scenarios. System design questions hit scaling web apps or basic microservices. They care more about solid architectural choices and explaining your thinking clearly. Skip the leetcode grind and review HTTP specs plus REST patterns instead. The bar isn’t crazy high, but you better be ready to defend your design decisions.
just wrapped up my hubspot interview! the http questions weren’t bad - mainly json responses and error codes. they had me debug a broken api integration, which was actually pretty fun. system design was way more relaxed than i thought it’d be - just basic web app architecture stuff. definitely practice talking through your approach out loud beforehand. they really want to see how you think through problems.
