First of all, I just want to say that I have no idea what those who had a bad experience are talking about-- I had a wonderful experience from start to finish! The first round was on campus with one product manager that was very informal. It felt very much like a conversation where we talked about what we're interested in, she told me more about the company and her experience, and asked me about my goals. I found out the next day that I was invited for final rounds up in their office. The final round was long but very enjoyable. It started with a quick conversation with HR where I talked about myself a little more (very basic questions) and he told me about the day. He really emphasized that he wants the day to feel two-way in that they would be assessing me, but they want to provide me all the information I need to properly assess them. I then was brought to a junior HR employee who asked me more creative questions (recommend your favorite book to me, what do you do in your free time, etc). I then took an assessment that was basic verbal logic and math-- really easy, just short time constraints. Then I had two interviews with very senior members, a lunch with new employees, and then two more interviews with other senior members (all were one-on-one). They were all very relaxed, back and forth interviews where they mostly asked general questions about myself. Lunch was completely informal and totally off the books. At the end of the interviews, I had one last meeting with the girl I interviewed with on campus just to review the day and next steps. I found out a few days later I got the offer (and the salary/signing bonus is awesome). Overall, a wonderful experience that felt very natural and provided a great feel for the role and company.
