01 · Preparation plan
Choose the next candidate using the problem's order.
eBay's compact catalog supports a selection-and-search preparation path. Two-pointer area optimization, merging sorted candidates, and a constrained board traversal require different notions of what to explore next. Use the linked design practice when relevant, without generalizing to all eBay roles or product architecture. This is a suggested practice sequence, not the employer's interview process. Your invitation and recruiter guidance remain the source of truth.
- 01
Justify moving the limiting boundary
Container With Most Water is useful for proving a two-pointer decision. Explain why retaining the shorter side cannot improve the result when width decreases.
- Test equal boundary heights.
- Separate area from height alone.
- Track the best result before moving a pointer.
- 02
Select from several sorted sources
Use k-smallest selection to maintain one current candidate from each source. Advancing a source should happen only after its candidate is consumed.
- Test empty arrays and equal values.
- Stop correctly when fewer than k elements exist.
- Express memory in terms of source count.
- 03
Model blocked movement accurately
Xiangqi horse reachability is a graph exercise whose legal edges depend on board constraints. Build the move validator before adding breadth-first search.
- Check intermediate blocking rules from the prompt.
- Reject moves outside the board.
- Test a destination geometrically close but unreachable.
02 · Broader technical practice
Practice beyond standalone coding questions.
These public eBay-tagged exercises cover additional technical formats. They are included only when a verified catalog record and a crawlable practice page both exist.

What “eBay interview questions” means here.
It means practicing transferable implementation, testing, and technical reasoning with public catalog assets FastPrep tags to eBay. It does not mean FastPrep has access to the company's assessments or any private interview bank.
Repeated public sightings and last-reported dates can help you prioritize practice, but they cannot predict the questions, format, or platform in a specific interview.
- Only eBay-tagged FastPrep catalog problems appear above.
- Stage labels and report dates remain visible as context.
- No official, private, leaked, or proprietary questions are claimed.
04 · Plain answers
eBay interview practice questions, answered plainly.
This page owns technical-practice intent for eBay. Hiring activity, timelines, and market signals remain on the separate hiring-insights page.
01Does this eBay page teach marketplace system design?
The public catalog includes some design practice, but this page does not claim complete marketplace architecture coverage. Its primary evidence supports coding exercises. Treat any design scenario as a practice problem, not documentation of eBay's production systems or a guaranteed interview round.
02Is FastPrep affiliated with eBay?
No. FastPrep is an independent interview-preparation product and is not affiliated with eBay. The page uses FastPrep's public practice catalog and does not claim official, private, leaked, or proprietary employer questions.
03How are eBay problems assigned to interview stages?
Stage labels come from FastPrep's public problem metadata. A problem can carry more than one reported stage, and hiring processes can change by role, level, location, and date. Treat the labels as preparation context, not a guarantee.
04Which eBay interview stage should I practice first?
Start with the stage named in your invitation or recruiter message. If no stage is known, use the largest available set to build general problem-solving fluency, then rehearse explanation and testing separately.
05Does this page predict the eBay interview process?
No. Public catalog counts, stage tags, and last-reported dates can help prioritize practice, but they cannot predict a specific interview's questions, sequence, timing, or platform.
