Summary: Interview Query swaps SQL practice for A/B testing

Why It Matters: The site is shifting its focus from technical coding tasks to product intuition and experiment design. This suggests they are targeting higher-level data roles that require business logic rather than just database skills.

What Changed:

• Replaced a technical SQL bank transaction question with a Facebook A/B testing product case study.
• Updated community stats: members grew from 69,750+ to 90,999+.
• Increased active discussion topics from 697+ to 899+.
• Increased expert coach count from 16 to 21.
• Fixed a typo in the partner section from "Micro" to "Microsoft."
• Removed several duplicate testimonial entries from the bottom of the page.
