I applied through other source. The process took 2 weeks. I interviewed at Airware (San Francisco, CA) in Jun 2014
Interview
My first impression came when I was contacted by a cold-call email. It struck me as unusual in how detialed and personal the content was. They had already researched me and my work. The following two phone interviews were both well thought out and professional (one technical, the other getting-to-know-you). The following two onsite interviews were friendlier and more targeted then what I have come to expect in this industry. There was one take home test as well. Later in the process, i particular appreciated there help and support transitioning out of my old position.
Interview questions [1]
Question 1
The hardest technical question I fielded was on threading, for which there are some interesting subtleties across various platforms. However, for me, I felt the most challenging question related to system architectural design.
