Applied late April and was contacted by a technical director himself after about a week. Did a phone interview about a week later. Didn't go through the HR department to schedule the interview. The tech director and I exchanged some informal emails about when to schedule the phone interview. The phone interview lasted about 15 minutes. He asked questions like how I handle pressure and fast-paced workplace, why I chose my major, what I can contribute to his department, and how I would solve an engineering problem with minimal information. Was contacted a day after to do a Skype interview. It was short as he mainly wanted to see the face of the intern before he hired. He asked why he should hire me and not other qualified candidates. Overall, it was very informal and fast.
