I was referred by a friend, then had a phone screening by a recruiter, followed by a phone interview with an enterprise team supervisor. Both phone interviews were standard, questions were focused on my background and customer service experience. I was asked in for an in-person group interview (three candidates, three interviewers) - the six of us met for a half hour, each interviewer took turns asking basic questions about background, what do you like about working in customer service, etc., then we each had two 30 minute individual interviews. All three interviewers were incredible nice and welcoming, and seemed mostly focused on finding someone who would be a good fit for the team and the LinkedIn culture. My advice is do your homework, know about the LinkedIn recruiter product, read some articles published by current employees about their experience, and do as many informational interviews as possible. Most of the questions asked called for specific examples ("Discuss an instance that you dealt with an angry customer, and how you dealt with the situation"). Overall, I had a great experience, and can't wait to get started!
