I was contacted by a recruiter. First step was a 15 minute phone screening about my experience, languages I know, and then a quick run down on what ONE does. Second step was a online test. Moderate in difficulty; one or two questions were ambiguous and unclear. Third step was a technical interview. Questions about OOP concepts, building SQL queries, one or two abstract problem solving techniques. I felt this part was fairly easy. Fourth step is another technical interview, this one I was asked about every language and technology mentioned in the job description. For me, this was the most difficult portion. Fifth and final: I had an interview with the manager for the team I was to join. Two very easy technical questions, then a long discussion about work styles and experiences. All my interviewers were very polite and professional. Also, the test and each interview (except phone screening of course) lasted roughly 1 hour.
