Phone Interview. The young lady that spoke with me told me she had just been rotated into the interviewing job, but was looking forward to talking with me. She noticed that I had taken and passed the LinkedIn Recruiter certification test that they administer.
She was very interested until about 10 minutes into the interview when she said "Wow, you have a lot of experience and job history." After that she said we were nearing the end of our allotted time.
When I asked what the next step was, she said that they had already hired someone and that I was a backup interview in case that person did not work out.
Note: I actually waited almost two months before posting this review. Since then the position has been posted several times (I realize they might have multiple positions), the young lady that interviewed me has left LinkedIn, and my business relationship officer has left LinkedIn as well.
