Best interview experience, hands down. The HR has been super nice and walked me through the whole process, which lasted 4 weeks. I started by answering some general questions in a phone call with the HR. Got the feedback the following day and proceed to the video interview with the director of product design. I walked through my portfolio and answered some high-level questions in design. After the interview with the director, I was given options to either do a video or onsite interview with the design team, which is an opportunity for the team to take a closer look to my previous work and ask questions. I choose to take a video interview and received the feedback soon. The final step before the onsite interview was a phone call interview with one of the PMs to talk about the design flow of a specific feature to evaluate your design thinking. Still, received the feedback quickly and got invited to the SF headquarter for the onsite interview. The HR offered me options to avoid red-eye flights and asked if I would like to stay longer in SF to explore the city - super sweet. The instruction for the onsite interview was clear and helpful, and they picked a nice boutique hotel within 7 minutes' walking distance from the office. The onsite interview lasted 4 hours, including a lunch break with the director of engineering. A whiteboard challenge with one of the PMs, a product critique with one of the product designers, some discussion about the role with the director of product design and some high-level review of the product with the VP. Everyone was nice, smart and insightful. The whole process was well-arranged, smooth and pleasant.
