Sorry, I just saw your reply. It has been quite an eventful past few months!

To answer your question, no, I didn't get the senior position. It went to someone much less qualified. Surprisingly, I actually enjoyed working with the guy, but after my discussion with the CIO for both my annual review and the news that I didn't get the position, I decided it was time to leave and accepted a position with another company. Similar title, but 30% increase, much more autonomy, and (best of all) only 40 hours per week.

I have actually stayed in contact with the senior ETL architect at the old place to help him along. Funny enough, a handful of people from that team followed me over to my current employer. Whoever said that the BI landscape has produced a mercenary culture nailed it on the head.
