A recruiter found my Linkedin and recommended the position to me. She prepped me for my first and second call with the team manager and another senior team member in a different city. I was asked to study some network protocols and prove my understanding on my second call as well as my technical knowledge in general.

Not too difficult. I had two interviews with the company but decided to pursue a different opportunity. The first interview was very general. The second interview was a little technical, and I had to learn a bit about computer networking.
