Interviewing Patterns & Anti-Patterns: Advice from the SQL Server Community
I’m glad I picked interviewing as the topic of TSQL Tuesday #93, because people wrote posts chock full of great advice and funny stories.

Do Index Changes Remove Execution Plans from Cache?
When you modify the indexes on a table, SQL Server needs to reconsider how it executes queries that reference that table. But the way this appears when you’re looking at your execution plan cache is far from obvious: Impacted query plans are NOT removed from cache at the time you change an index. The next time the query is executed, it will be recompiled, and the new plan and related execution information will be placed in cache.
The Story of an Interview Flop
Some of the biggest lessons I’ve learned about interviewing come from an interview experience that meant a ton to me – and all my dreams came crashing down.

Did that Query Eliminate Partitions? (videos)
Table partitioning makes execution plans a bit more confusing. I have a free online course which walks you through decoding execution plans, including whether or not partition elimination occurred.
