Rectangle Overlap
A easy-tier problem at 46% community acceptance, tagged with Math, Geometry. Reported in interviews at Qualcomm and 1 others.
Rectangle Overlap has shown up at Qualcomm and Nvidia, and it looks deceptively simple. You're given two rectangles defined by their coordinates, and you need to figure out if they overlap or what the overlap area is. The acceptance rate sits at 46%, which tells you most people miss a critical edge case or get the coordinate math wrong under pressure. If you blank on the geometric logic during your assessment, StealthCoder surfaces a working solution in seconds, invisible to the proctor.
Companies that ask "Rectangle Overlap"
Rectangle Overlap is the kind of problem that decides whether you pass. StealthCoder reads the problem on screen and surfaces a working solution in under 2 seconds. Invisible to screen share. The proctor sees nothing. Built by an Amazon engineer who used it to pass JPMorgan's OA and system design loop.
Get StealthCoderThe trap is assuming overlap means touching. You need to check if two rectangles actually share interior area. The algorithmic trick is straightforward: two rectangles overlap if their x-ranges overlap AND their y-ranges overlap simultaneously. Each range overlaps only if one rectangle's left edge is strictly left of the other's right edge, and vice versa. Most candidates forget the strict inequality or confuse how to compare coordinates. When you're coding live and second-guessing whether touching edges count as overlap, that's where the pattern breaks. The math is clean once you see it, but under interview pressure and limited time, the coordinate comparisons become ambiguous. StealthCoder handles the boolean logic and edge cases so you can move forward.

Rectangle Overlap recycles across companies for a reason. It's easy-tier, and most candidates blank under the timer. StealthCoder is the hedge: an AI overlay invisible during screen share. It reads the problem and surfaces a working solution in under 2 seconds. Built by an Amazon engineer who used it to pass JPMorgan's OA and system design loop.

Rectangle Overlap interview FAQ
Is Rectangle Overlap actually asked at FAANG-tier companies?+
Yes. Qualcomm and Nvidia both report asking it. It's a geometry screening problem, typically used early to filter for spatial reasoning and coordinate-system comfort. You'll see it more often at hardware and systems companies than pure software shops.
What's the trick I'm missing if I get the logic wrong?+
You're likely treating edge-touching as overlap or using the wrong inequality operators. Remember: two ranges [a, b] and [c, d] overlap if and only if a < d AND c < b. Swap or reverse the inequality, and you'll get false positives or negatives.
How does Rectangle Overlap relate to the Geometry topic?+
It's foundational coordinate geometry. You're working with 2D axis-aligned bounding boxes and applying range logic independently to each axis. This pattern appears in collision detection, spatial indexing, and graphics. Master this and you unlock intuition for harder geometry problems.
Why is the acceptance rate only 46% if it's marked Easy?+
Easy difficulty doesn't mean obvious. The concept is simple, but the implementation trips people up. Off-by-one errors, mishandled edge cases, and confusion about what counts as 'overlap' during a timed assessment push the failure rate higher than expected.
Do I need to compute the overlap area or just detect it?+
That depends on the exact problem statement, which varies. Some versions ask for true/false overlap detection. Others ask for the area of intersection. Both use the same range-intersection logic, but the second requires one extra multiplication step if overlap exists.
