Got an email few hours after applying to schedule an interview on site. Two weeks after I went to the company for the interview. Few words with the CEO first about what I can do then a programming challenge for 2 hrs and half on their laptop (you can google) .

Phone screen first, then one round on site interview with CEO and 2 engineers. Start from general questions about previous projects experience, availability, academic degree, behavior questions. After Q/A interview, also gave me a computer to write the real code in Visual studio, including how to open/close/read/write files. I was told I could google if I need.
