finished my airbnb product designer loop about three weeks ago and wanted to write something more specific than the usual 'prepare your portfolio' advice.
i'm a staff designer, 9 YOE, so my loop was calibrated for senior/staff level. i imagine the new grad and mid-level experience differs in scope of what they expect in your cases.
Portfolio review format: 60 minutes, 3 interviewers (design lead, another designer, a PM). they asked me to walk through 2 projects in depth. i chose a consumer product end-to-end redesign and a complex multi-stakeholder B2B workflow, thinking the contrast would show range. in retrospect: airbnb is consumer. they connected more with the consumer case. know your audience.
what they pushed on hard: the messy middle of the design process. not 'here's the beautiful final screens' but 'walk me through the frame where you had 3 competing directions. how did you decide?' they want evidence of structured ambiguity, not a clean linear story. real design doesn't go from research to wireframes to final without detours.
What differentiated the interviewers' follow-ups: How did you incorporate accessibility constraints from the start (not as an afterthought)? Walk me through a time the research pointed one direction but the product/eng constraints forced a different call. how did you handle that tension? How do you know the design worked? (they want metrics, not vibes. show them that you can connect design decisions to outcome data.)
The values/behavioral round: designers get the same core values interview everyone else does. "be a host" lands naturally for designers: the whole job is making someone else's experience feel cared for. have a story ready.
One thing that surprised me: they had me do a short in-room design exercise. 20 minutes, whiteboard-style, design a feature for an edge case user (they gave me a specific user scenario). i was not expecting live design and it threw me for a moment. recover fast and talk out loud the whole time.
overall the process felt genuinely respectful of design as a discipline. the PM on my panel asked thoughtful questions, not just 'can you ship fast'.
