Roles and responsibilities in ISP – L1 Executive


As an L1 junior executive in ISP Provides an entry-level experience for any fresher. There are many ISPs in the country who are willing to provide part-time to full-time jobs in L1 support. I began my first full-time job as the L1 junior executive at Vianet PVT LTD in Nepal. I had no experience before with a real job in Networking. Previously, I did my internship for a college final project where I had little experience with how ISPs operate in real time.   I did my bachelor’s in computer science and Information Technology.

The basic Networking concept was known to me. The interviews taken by HR were pretty basic and related to Router, switch, DNS, IP address, DHCP, and how it works. It was pretty decent, I did 2 rounds of interviews in a week for the selection procedure to be completed.  The roles and responsibilities in ISP as an L1 executive are responsible for ensuring a positive customer experience by providing timely support.
