The interview process was like any other technical role interview. One behavioral interview on the phone with a non-technical recruiter. As long as you be yourself and show some degree of caring, you should make it to the second round. The second round interview was also on the phone with two team members. The second interview was technical with an onslaught of networking questions. The interviewers desire to get an understanding of how deep your knowledge base is. Be prepared for follow up questions after nearly every question. Be sure to prepare and to study non-vendor specific solutions to problems. Be aware that two engineers will be asking questions, as you are answering one question, the other will be pondering on the next questions. Please study - basic questions can be forgotten.

1st round interview, very basic questions. Why SIG, background, interests, qualifications. No technical questions pertaining to network. Did not get advanced to 2nd interview though. Not sure why they would decline even though I didnt get asked any technical questions.
