Analytics at Amazon (Bangalore)

Hey all! Needed some insights on how analytics is at Amazon. I see a few Business Analyst roles here. I've been working in start-ups so far.

Few things I would like to know:

1. Career progression
2. Learnings
3. Culture
4. Tech stack (I see VBA as one of the requirements in the JD - just want to ensure they don't have legacy practices)
5. Pay

I'm at 3.5 YOE now.
