The process had 5 parts.
1. Screening with a recruiter.
2 & 3 were trivia style questions
4 was a take home project
5 onsite.
I had interviewed with this company for over a month because of scheduling conflicts and lack of communication on their end. Their recruiters would often take over a week to get back to me. I easily completed their second and third interview but got a call that I wouldn't move on to the fourth because they had already filled the last of the roles.
I applied online. The process took 3 weeks. I interviewed at Mobiquity (Amsterdam) in June 2016
Interview
The interview process consisted of three stages: two skype interviews and a technical 1:1 interview with a senior developer. The first and the last interviews were really informal and brisk, so I liked them very much. The second (skype) interview with the tech lead was more formal and only concerned the past experience, but, also, did not take too long. Overall, I would say that the interviewing process was very quick and more mature than in many other places I have had experience with.
