Using IFNULL() on a Google SQL Interview Question

This video will walk you through Google's "Videos Removed on Latest Date" SQL interview question. We explore two datasets and use of IFNULL() function and SQL queries to find the latest date when flags got reviewed for each unique user, and then determine the total number of distinct videos that got removed on that date. Along the way, we discuss important SQL concepts such as filtering, joining, and aggregating tables. Join us to see how we solve this hard-level problem!
