Reddit, Inc. Software Engineer Interview Guide

The Reddit interview process is structured and follows a predictable flow across four distinct rounds. It opens with a conversation focused on background, experience, and general fit questions — nothing surprising there. The second round is where the technical weight lands: you'll solve LeetCode-style coding problems, and from what I encountered, these ranged in difficulty. I was given a 2D array problem involving detecting rectangular regions of zeros surrounded by ones, then extending it to handle multiple rectangles and checking whether points fall inside them. The logic required careful coordinate tracking and pattern recognition, but it wasn't particularly exotic — the kind of thing you'd see in a medium-difficulty LeetCode problem.

The third round shifts tone entirely. This is with the hiring manager and is much more conversational. They ask topic-specific questions that tie directly to the job description and the team's actual work, so reading the role carefully beforehand really matters here. They're assessing both your technical depth on areas relevant to the team and your communication style. The fourth and final round is with the broader team. It's a chance to see how you'd work with actual colleagues and whether there's genuine fit. It feels less like an interrogation and more like a real conversation about how you'd approach problems together and integrate with their way of working.

One thing I didn't anticipate was the SQL component. Depending on the role, you might get a straightforward SQL question alongside the algorithmic work — nothing overly complex, but it's worth brushing up on basic queries and aggregations just in case. The whole process felt standard for a tech company of Reddit's size: organized, thorough, and designed to test both problem-solving ability and cultural alignment. I didn't advance past the technical stages, so I can't speak to later rounds with confidence, but the structure itself is solid and fair.
