I applied in-person. The process took 4 weeks. I interviewed at Duo Consulting (Chicago, IL) in Apr 2015
Interview
I had met the development director at a Drupal meetup and sent him my resume. I had a ~20min phone interview with him and then came into the office for an in-person interview with him, the company owner and the lead front-end developer.
Interview questions [1]
Question 1
I was expecting more technical question but only got a few regarding what functionality I had included in previous Drupal sites that I had built and a question about what modules are my favorites.
