Wayfair Interview Questions (2026-2027)

YOE: 3.5 Years Role: Backend Engineer ⸻ 🟢

Round 1 Online Assessment (HackerRank) • Received a HackerRank link. • There were 2 DSA questions (LeetCode Medium–Hard level). • I was able to solve both within the given time.

Outcome Cleared the round. After 2 days, I received a call from the recruiter confirming the

next round. There was some delay in scheduling due to slot availability. ⸻ 🔴

Round 2 Machine Coding Round (40 mins) There was a technical issue on my system initially, and the first 10 minutes were spent resolving it. The interview started with some delay.

Problem Statement: Given a list of packages with: • Weight • Height • Width • Length • Distance We had to calculate: • Transport Charges • Service Charges • Overall Cargo Cost Charges were based on package type: • Standard Transport: 0.5 × Volume Service: 0.5 × Weight + 0.5 × Distance • Hazardous Transport: 0.75 × Volume Service: 0.75 × Weight + 0.75 × Distance • Fragile Transport: 0.625 × Volume Service: 0.625 × Weight + 0.625 × Distance Volume = Height × Width × Length We were given interfaces for package and shipment, and asked to implement the calculation logic, insert/remove packages, and compute total costs for the cargo. The time limit was 40 minutes. ⸻

My Approach • Started by defining POJOs and basic structure. • Used Strategy Design Pattern to calculate charges based on package type. • Implemented core logic but could not complete the entire solution within the time limit. • Initial delay and spending extra time defining structure affected completion. I felt I could have coded it faster with better time management. ⸻ ❌

Verdict

Rejected ⸻ 📌 Key Learnings • Machine coding rounds require speed + clarity. • Avoid over-engineering; focus on working solution first. • Time management is critical. • Handle unexpected technical issues calmly and adjust quickly.
