Got rejected by Wayfair recently. Wanted to share my experience.

Process:

• OA - 2 DSA questions
  • A BFS question with a n * m and upto k steps that can be taken per move in a given direction.
  • Don't remember the second question, but it was straightforward.
• Interview - Coding round
  • Categories and their Coupons. Categories are like a tree (i.e they have parents).
  • For a category, find it's "nearest" coupon + one extension question it.
• Interview - Low Level Design
  • The infamous Parking Lot: https://leetcode.com/discuss/interview-question/6003635/WayFair-Automated-Parking-Lot-Problem-Design/
  • I had to draw the class diagrams, DB schema, and API. Was grilled during class diagrams. Didn't get much time for the API part.
• HM and HR (separate rounds) - On Site
  • Classic behavioral questions

Verdict: Rejected
Feedback:

• I had given the rounds in coding rounds in a language other than Java. I wasn't aware this would be such a dealbreaker even though I had communicated during the HR and HM rounds that I had experience in Java.
• My design and HM round were not up to the mark. Though I'm not sure why I had to go onsite if my design round wasn't that great.
