I applied online after attending a conference where they were hiring for mostly hardware engineering roles.

After applying, I received an email via HireVue asking me to answer a few questions and record my responses.

Shortly after, I received another email asking for my availability in order to schedule a 1-hour interview with a manager from California.

The next day, I received a call where they wanted to fly me out to Dallas, TX for the final interview. They wanted me to prepare a 10-minute presentation describing a technical project I worked on.

Most of the questions were based on my project. I had two one-hour interviews with two people each. One asked me to derive the transfer function for a circuit that he designed while I was presenting. The other group asked me to solve an equation that they had on the board.
