Wayfair has one of the best interview processes. Though I was not offered a position, I felt really good about the company. Recruiters were really nice and organized.

I completed a total of 6 rounds of interviews: 3 telephonic and 3 in-person. After the telephonic interviews, they asked me to fly to Boston. Wayfair actually paid for my flight, hotel, and other expenses, which was nice.

In every round after the first call, there was a coding task. Though I was not able to complete the coding task during the 2nd and 3rd rounds, they still called me for onsite interviews because they liked my approach to problem-solving.

In-person interviews were more like discussions than question-and-answer sessions.

The 4th round was with an Engineering Manager who grilled me about the process.

The 5th round was with Software Engineers, who asked me a programming question about elevators and another about system design.

The 6th round was with Software Engineers again. This time, they had me complete an actual coding task and a database design.

Design a system to shorten URLs.

Design a database system for storing check-ins at a place.

Write code to save data into a cache with a maximum limit of 5 records, meaning, keep the most recently used records only in the cache.
