The first interview stage is a 1-hour phone interview, which was very skills-focused although it did include a more traditional question or two. The second stage is an in-person interview with the engineers that, based on the times I was offered, lasts from 1 PM to 4:30 PM. Sometime during that interview, a conference call is made with the company's CEO in South Korea as well, which can be considered the third stage of the process.
