10 eBay Software Engineer (New Grad) Interview Questions (2026)

eBay's new-grad SWE loop in 2026 is a recruiter screen, an online coding assessment, a technical phone screen, and a 4-round virtual onsite covering coding, system fundamentals, behavioral, and team match. eBay is one of the original e-commerce marketplaces; expect questions on auctions, search, and high-volume transactions.

Loop overview

New-grad candidates report a 4-7 week timeline in 2026. Online assessment (2 problems, ~75 minutes), then a 1-hour phone screen. Onsite: two coding rounds, one system fundamentals round, one behavioral + team match. Stack is Java heavy on backend, JavaScript/TypeScript on frontend.

Behavioral (4)

Tell me about a time you debugged a complex problem.

Frequently asked

Outline

STAR. Pick a real bug. Show the diagnosis steps, hypotheses tested, the resolution, and what prevented recurrence. eBay handles high-volume transactions; debugging is a real skill.

Describe a time you worked on a legacy codebase.

Frequently asked

Outline

STAR. eBay has significant legacy code (Java, some older patterns). Pick a real moment with an inherited codebase. Show how you navigated, the changes you made, and the outcome. Generic 'I love refactoring' lands flat.

Tell me about a time you took on a project outside your comfort zone.

Occasionally asked

Outline

STAR. Pick a real moment when you stretched. Show the ramp-up, the work, the outcome. eBay values curiosity and learning velocity.

Coding (LeetCode patterns) (4)

Given a list of integers, find a contiguous subarray with sum equal to a target.

Frequently asked

Outline

Prefix sum + hash map. For each prefix sum, check if (prefix - target) was seen. O(N) time, O(N) space. Walk through with a small example. Edge case: subarray of length 0 (depends on definition).

Implement a function to find the cheapest listing in a price-range filter.

Frequently asked

Outline

Filter listings within [min, max], find min price. O(N) time. For many queries with sorted prices: binary search lower bound. eBay's price filter.

Given a string, return the count of vowels and consonants.

Occasionally asked

Outline

Iterate, count vowels via set lookup, count alphabetic non-vowel as consonants. O(N) time, O(1) space. Edge cases: case sensitivity, non-alphabetic chars (skip).

Implement a function to detect whether a graph has a cycle.

Occasionally asked

Outline

DFS with three states: unvisited, in-progress, done. A back-edge to in-progress = cycle. O(V + E). Undirected graph variant uses parent tracking instead.

Technical (2)

Implement an auction system: given a list of bids, return the winner and the price they pay (second-price auction).

Frequently asked

Outline

Sort bids descending. Winner is highest bidder; price is the second-highest bid + minimum increment. Walk through with ties, single-bid edge case, reserve-price violation. eBay's actual product (Vickrey-style for auctions).

Design a service that calculates shipping cost given source, destination, and item weight.

Occasionally asked

Outline

Concept-level. Inputs: zip codes (or country/postal), weight, shipping class. Approach: zone table lookup (source × destination → zone), then weight-band pricing per zone. Discuss caching, batch lookup, carrier overrides. eBay's actual problem.
