Hi guys,

yes, there is a difference in job scope.

level 1 is (obviously) the basic level, here most of the time you'll just be doing monitoring jobs and only basic troubleshooting (ping, telnet, etc if you are in network support like me ). mostly composed of fresh graduates. a.k.a operations monitoring, command centre, etc.

level 2, more troubleshooting (with advanced commands) and less monitoring. higher responsibility and also higher skill level is needed to work here. usually known as technical support.

level 3, is the most otai of the 3 la. troubleshoots problems that nobody else can solve. usually known as deep technical support.

there, hope it's helpful! peace out guys!!
