HubSpot Software Engineer interview: banking-system assessment and system design rounds

My process started with a coding assessment under tight constraints. The time pressure felt real, and the tasks were divided into multiple levels. Each level opened only after I completed the previous one. I didn't get through all the levels. The prompt involved designing a banking system, so it went beyond standard LeetCode mechanics.

In another attempt, the CodeSignal online assessment was also where things fell apart. I was later contacted about continuing because they were reevaluating my CodeSignal result as a signal. The process then moved to a recruiter conversation with basic STAR-style questions, followed by technical rounds. The final stage included several interviews focused on system design and coding. That time, I was rejected after the technical work.

What stayed with me was how much both the early assessments and the deeper technical stages depended on the details of the reasoning. Logic mattered, as did specifics such as time complexity. I also learned that when a process depends on a few checkpoints, one small miss can stop the momentum, even when I felt prepared going in.

Location: New York, NY. Overall feedback: Positive. Offer status: No offer.
