I applied in-person. The process took 4 days. I interviewed at We Are Mobile First (Barcelona) in Jun 2018
Interview
In the first step, I met the CTO at the agency to get to known each other better. We talked about Design Patterns and iOS SDK. In the second step, I met their iOS senior developer and the CTO for a 15 minute technical interview about one of my latest projects. Then I received the offer.
