Wayfair Staff Software Engineer interview questions

Initial karat interview for 1 hour. I was asked questions on system design and then a coding question for 30 mins. The team expected me to provide the working solution to coding question 1. I checked with my recruiter and decided to take a redo. The redo interview had an object-oriented design question and then a coding question. Coding question: Ancestor of two numbers given a 2d array. I was able to provide the complete solution this time but couldn't handle 3 of the test cases out of 12.
