Question 1
They wanted to know as an engineer what my process for working with designers and product owners was.
The process took 3 weeks. I interviewed at Spring in Feb 2015
Interview
They emailed me a coding challenge to be completed in 2-3 days. Upon completion, I was scheduled an interview with an engineer - it was slightly behavorial but mostly technical that lasted about an hour. Afterwards, another technical interview was scheduled that lasted 2 1/2 hours with 3 engineers taking turns talking to me and asking me to code/answer technical questions.
The recruiter was very helpful the entire time and everyone was a pleasure to talk to.
