Laalmon,

Typically when you go as a admin, it is understood that you have a fair to good understanding of developers work.

But do not think too much into it, if your job description was strictly for Admin job.

About managers/leads talk talking to you,its not necessarily a bad thing. Either you are doing your job or they don't have anything for you yet. It usually a bad sign when your supervisor comes talks to you.

I work as a developer and i hardly talk to my manager. Its not personal, just business!

Hope this helps!

The Nepali.
