Left the Giant

Yesterday marked my last day at vodafone VFE.
I had very nice three months working there, I gained a lot of knowledge about the telecommunications world, the production and application support as well as the meaning of systems analyst title and what is OnCall all about.
Vodafone Egypt is a very nice place, its facilities and buildings are very well designed and organized.
Multinational companies and corporates, it is all about the hierarchy, reporting tree, escalation matrix, service level agreements, policies, off-site meetings, outings and tight workflow of change management.
I was never before this point in time; a client, they gave me this very new perspective of being 'the client' and having 'vendors', how to deal with that, get what you want from vendor and serve your own 'clients' who ranged from the normal person (subscriber) to dealers, agents and even internal employees.
I also never worked that close with sun microsystem servers, i had the opportunity to bounce against the command line of unix.
The job was systems analyst, which is all about supporting running applications, constantly monitoring and solving any raised trouble tickets and escalating them to vendors if resolution is not clearly defined in documents...
VFE is a big company with lots of departments, many lines of support, a special atmosphere and environment that you could hardly forget.
And yes the OnCall part, this was new to me as well, in OnCall you have to be in a standby mode for 24 hours during the days you were scheduled to be OnCall.
You then might receive phone calls or sms indicating the state of certain systems upon which you have to act, acting might require going to the headquarters data center or you could just solve it from your laptop using your connect card based upon the severity of problem.
It was a great experience, but gradually I felt I am losing the only thing I could do well, that is, development and planning.
In applications support you are taken away from development, planning, and anything related to the roles and tasks you used to have when you worked as a software engineer/developer.
When I handed over my resignation, I truly believed that this job is so early for me, although it is not hard and could be done but once you are totally in you will never know or be good at anything else, which decreases and eliminates my options and chances to work anywhere else later on.
It is sad that I had to leave such a nice company but anyways..I wish all its people the best of luck.
