Costco warehouse candidates in 2025-26 describe two to three in-person behavioral interviews: a first round with one or two supervisors or a department manager, sometimes a panel, and a final round with the general manager, an assistant general manager or the warehouse manager, followed by a drug test and background check. Questions were about why Costco, difficult coworkers, urgent problems, pressure, sudden workflow changes and dealing with members, and stocking candidates were asked whether a 4 a.m. start was okay.
Speed varies widely. A Garden Grove deli clerk went through three interviews in one day, while a Portland front end assistant had to keep calling to move the process along, and some candidates waited weeks between rounds.

Detailed interview experiences
Experience 1: Three rounds, Front End Assistant (May 2026)
Process: Applied in person. First interview with two managers, then the warehouse manager.
Questions: Why did you choose Costco? Tell me about working with a difficult coworker. What urgent problem did you face, and what was the result?
Takeaway: Be early and say you are dependable. The reviewer noted the three-minute clock-in grace period and advised showing you are ready for the probation period.
Experience 2: Same-day interviews, Garden Grove (2026)
Process: Two supervisors, then the AGM the same day. The AGM told the candidate to do a drug test and background check on the spot.
Outcome: Hired about two weeks later.
Takeaway: Come prepared for more than one interview in a single visit.
Experience 3: Persistence, Portland (2026)
