Wayfair Interview Process for Software Engineers

Before you start preparing answers for common interview questions at Wayfair, it's crucial that you understand the interview process.

Here's what you can expect:

1. Recruiter Call

During this call, the recruiter will give you an overview of Wayfair's business. They will then explain the role (and possibly other related roles) to understand if you would be a good fit.

2. Technical Screen

You can expect system design and coding interview questions during this interview round at Wayfair. The test is conducted over Karat, a technical assessments platform that provides a fully tooled IDE to candidates.

Apart from Karat, the company also utilizes other assessment tools, depending on the requirement of the role (like if you need to work on a case study). Either way, the recruiter will brief you about it so that you can be prepared for the interview questions.

3. Phone Screen

In the phone screen at Wayfair, you can expect interview questions regarding work and thought processes. The best way to answer these questions is using the STAR (Situation, Task, Action, Result) method.
