Phone interview, followed by a lunch meeting, followed by a day of interviews.
1. Phone interview:
A standard discussion about portfolio of work, interests, experience and design processes. With a few questions specifically about the area/project I was applying for. The main purpose seemed to be to gauge my design competency.
2. Lunch Meeting:
Met hiring manager and team director for lunch on-campus. We talked very casually, again about my work, the project I was applying to work on, and more about design systems and projects management. The main purpose seemed to be to gauge my personality and compatibility with Google culture.
3. Day of interviews:
Presented a homework assignment and portfolio presentation to a group of designers, project managers, researchers and engineers, none of whom where on the team I was applying to join (this is a strategic thing). About 8 people in total. Then, had individual 1 hour interviews with a few of them, each focussing on different areas of connection they would have with a designer like me. In other words, the researcher asked me about design testing, the engineer asked about optimization of assets and flow, the project manager asked about how to deal with conflicting opinions and settle on a good decision, and the designers set me a mini design challenge.
There were no trick questions or brain teasers.
