Story of my previous company (mine was around 3000 employees company with a DBA team around 15 people in different verticals, sql server 4 people were there in which one is MVP )=>

I got 3+ year exp, in which 2 year was Appln Dev from there got into DBA team. Initially with my PM's (he was the primary DBA for that project) guidance i been in DW project, in which i did the same task of yours creating Dimension and fact tables writing Stored Procedure, using Dynamic Task to configure server, I used INI files rather than tables as client was comfortable with that. I did the same task as yours my other DBA team members most of them were atleast 5+ year exp, so they were not comfortable intially seeing me in DBA team with zero exp. Mine was little bit dev kind of work initially so still they were not comfortable with DW or my kinda of work. But I proudly say I could win the heart of all those well experienced DBA's and also almost all the Sql developers in the company. My greatest dream was to become MVP for which my peers encouraged me and the MVP in our team guided and mentored me. But I couldnt be MVP, as currently i am working for Microsoft... I miss my old firm, old DBA team, DB/other developers , my old PM, everyone ...

I think either you were in wrong crowd  or things didnt turn good for you there... Attitude plays a big role in this kind of job...

Thanks,
