MySQL for Business Intelligence

Hello everyone,

I am about to do an interview for a BI Analyst position, and just wondering if anyone in this forum may be able to offer some insights on how proficient I have to be, and any recommended materials that I should cover aside from the MySQL course that Mosh provided. I have finished Mosh’s MySQL course and have finished w3schools’ exercise – I was hoping I could get some more exercise as the first interview would be technical.
