I had 2 interviews. First was with HR who asked simple behavioral questions. The second was with the manager who asked networking related questions and discussed the timings of the job. The networking questions were focused on OSPF, EIGRP and mainly BGP. In some cases, senior engineers conduct the interview instead of managers.

One day process. with four rounds. HR, technical, communication skills. Most imp is the technical round. You need average english speaking skill to get through communication skills round. all based on ccna knowledge. questions were on routing protocols and cmd line. Thank you
