Wayfair Software Engineer II interview questions

Initial call with the recruiter. This was followed by a phone interview round with coding on a shared editor(coderpad). Problems were of algorithms(language of choice), design patterns(PHP), debugging(SQL). Each round had a panel of 2 interviewers This was followed by an onsite with 4 rounds involving 2 technical. Technical Questions centered around System Design, Object Oriented Design, Database Design and SQL Queries. The final round was with the Director of the division and was more about my experience and what I was looking for and me asking him questions in return

I first had a brief phone interview with a recruiter who told me a bit more about Wayfair and the position. We chatted about my background and the recruiter had me answer some basic technical questions to gauge my knowledge. After that, we scheduled a time to have a longer interview with one of the lead engineers over the phone, along with a coding test. The engineer was very friendly and easy to talk to. The coding test covered a variety of topics - SQL queries, a read-through of some prewritten PHP, and a coding challenge in language of your choice.
