Hey Richard, great video. Used this to refresh some basic interview skills last night before a panel interview today. I got the job after one single tech question. The question was "walk me through your methods to performance tune a TSQL Query?" Briefly, my answer touched from top to bottom, starting with index evaluation/improvements, to query syntax and known issues, to under lying OS disk alignment, RAID, CPU config, maxdop etc.
