Simple skype interview to learn my skills, then asked what kind of environment I preferred to work in. Ended up telling me that he will refer to another recruiter that is more suited for my area of work.

The interview was thorough. There were five stages. The first was a 10-minute phone interview which was mainly focused on prior work experience and current employment. The second was a 30-minute Skype call with a recruiter and the head of Robert Half's Salaried professional services manager. After that, They asked me to come in to meet the sales team which was a team of 5-6 people interested in current skills, preferred technologies, and libraries. The fourth stage was a written assessment test, taken online, and at your convenience. And lastly, a technical phone interview with a current Robert Half developer.
