This starts with a recruiter contacting you (typically based on an application). Recruiters are very nice to talk to and explain the entire process nicely and are very enthusiastic and detail oriented. After this initial discussion, they would arrange for 1 hour interview on coderpad for technical round - typically on SQL and Java (or any language of choice). Wayfair uses C# and PHP, but they are language agnostic during interview process. After the technical screening, they would invite for roughly 6 hours of onsite interview on a Monday (the interview day). This involves 30 mins with recruiter in the beginning and also at the end. And 4 sessions of 1 hour each (and thankfully they sprinkle in a lunch break with a colleague for additional QnA). In these 4 sessions, one of them is with a manager who has many behavioral questions, project experience (essentially walking thru the resume). During the system design phase, 2 engineers would ask to design a system e.g. how to setup a tinyURL site, or twitter like site, but usually a simpler problem. And they would build upon that requirement during this 1 hour session. Another round is for database design where 2 engineers would ask to design a database (with ER diagram) and then test the SQL skills. Again, trying to add more complexity as they go along. In Final technical round, 2 engineers would go back to Coderpad to solve a coding assignment. Usually a simple question, and they would prefer end to end compilation and testing. They would like to see you talk thru the design and implementation approach.
