The process began with a 30-minute technical interview at my school. The next round of interviews took place at the Austin, Texas office. They flew me down and paid for my hotel and other expenses.

On the evening I arrived, all the interviewees attended a dinner with HR representatives and some Software Development Engineers (SDEs).

The following day started early, with a meeting at 8 AM at the office, which is about 20 minutes outside the city. We were provided breakfast, and then split into two groups. My group started with the technical interviews. I had three back-to-back technical interviews, each with one to two interviewers. I felt good about all of my answers to the questions.

After that, it was lunchtime, where we ate with everyone – both interviewees and employees.

Following lunch, the groups switched. I then completed an hour-long coding exercise, followed by approximately two hours of presentations. That concluded the interview process.
