Google Hardware interview questions

two phone interviews. First talking to the project host, who asked about some general technique questions such as how to design IC timing, or how to solve a specific security problem. Second interview was talking to the another engineer in the same group, more specific technical questions, especially coding on a google doc. Both interviewers are friendly, they will explain their solutions after each question.

I applied for a specific group. I got two phone interviews. The two interview are both asking specific question related to the team. One interview is focus on general knowledge about the team background and the other interview is to design an algorithm. The interviews are both very experienced and are helpful of answering the questions.
