Recruiter/Hiring Manager Call Screening

If your CV is among the shortlisted few, a recruiter from the Wayfair Talent Acquisition Team will contact you and verify key details like your experiences and skill level. Behavioral questions may also be part of the screening process.

Sometimes, the Wayfair hiring manager stays present during the screening round to answer your queries about the role and the company itself. They may also indulge in surface-level technical and behavioral discussions.

The whole recruiter call should take about 30 minutes.

Technical Virtual Interview

Successfully navigating the recruiter round will invite you to the technical screening round. Technical screening for the Wayfair Product Manager role is usually conducted virtually, including a video conference and screen sharing. Questions in this 1-hour long interview stage may revolve around project management methodologies, product lifecycle understanding, and data-driven decision-making.

Technical assessments may include case studies focused on product optimization or A/B testing scenarios. Depending on the role, technical exercises may also be sent to evaluate your ability to work on real-scenario problems.

Onsite Interview Rounds

After a second recruiter call outlining the next stage, you’ll be invited to attend the on-site interview loop. Multiple interview rounds, varying with the role, will be conducted during your day at the Wayfair office or virtually due to current conditions. Your technical prowess, including your understanding of product management principles and problem-solving skills, will be evaluated against the finalized candidates throughout these interviews.

Onsite interviews usually cover behavioral interview questions, past experiences, and a short case study. One of the interviews typically involves discussing a problem that Wayfair users encounter and how to address it with measurable impact. If applicable, a presentation round based on pre-assigned take-home exercises may also be a part of the onsite interview.

Typically, interviews at Wayfair vary by role and team, but commonly product manager interviews follow a fairly standardized process across these question topics.
