Node With Highest Edge Score
A medium-tier problem at 48% community acceptance, tagged with Hash Table, Graph. Reported in interviews at Juspay and 0 others.
Node With Highest Edge Score is a medium-difficulty graph problem with a 48% acceptance rate. It's been asked at Juspay. The setup is straightforward: you're given directed edges, and you need to find the node with the highest sum of incoming and outgoing edge weights. The trick isn't the concept; it's the implementation. Most candidates either overcomplicate it or miss a detail in how they aggregate the scores. If you hit this during a live assessment and freeze on the edge-weight logic, StealthCoder solves it invisibly in seconds with a working solution.

Node With Highest Edge Score 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. Made for the engineer who has done the work but might still blank with a webcam pointed at him.
Get StealthCoderThe problem requires you to track two separate sums per node: weights of edges coming in and weights of edges going out. A hash table (or dictionary) is the natural fit. The pitfall: candidates often either forget to initialize nodes before accessing them, double-count self-loops, or mix up the direction of edges. The obvious brute-force approach works fine here, but the real challenge is clean iteration and avoiding off-by-one errors. Once you've built your incoming and outgoing maps, finding the max is trivial. Where candidates stumble is edge cases: what if a node never appears in the edge list. What if there are self-loops. What if multiple nodes tie for the highest score. Hash Table and Graph are the core topics because you're building an adjacency structure and querying it. StealthCoder is your hedge if you blank on the aggregation pattern during the real assessment.

Node With Highest Edge Score interview FAQ
Is this problem about finding a shortest path or traversal?+
No. It's purely a scoring problem. You're summing weights, not searching. No BFS, DFS, or Dijkstra needed. Just iterate the edges once, accumulate incoming and outgoing weights per node, then return the node with the max total. Hash Table is all you need.
How do I handle nodes that don't appear in the edges?+
A node only exists if it appears as a source or target in at least one edge. If a node never appears, it's not in the graph, so you don't consider it. Initialize scores only for nodes you encounter. Most languages let you use a defaultdict or check before access.
What about self-loops or repeated edges?+
Self-loops count both as outgoing from a node and incoming to itself, so you add the weight twice to that node's total (once to outgoing, once to incoming). Repeated edges are processed as separate entries, so weights stack. The problem statement will clarify if edges are unique.
Is this still asked at Juspay?+
Juspay is the only company with a public report of asking it. Medium-difficulty graph problems are common in backend and infrastructure interviews. It's a solid leetcode-style screening question, especially for roles handling network or transaction graphs.
What's the time and space complexity?+
Time is O(n), where n is the number of edges, because you iterate each edge once and update hash tables in constant time. Space is O(m), where m is the number of unique nodes, to store the incoming and outgoing maps. No extra traversal needed.
