So I’ve been going over datacamp and have completed the intermediate sql and the course on Joins etc but recently I tried taking a test for a product firm that required SQL and most of the questions were on joins but I just scored a 12/22. Additionally I am trying to solve the intermediate questions on hackerank related to SQL and I am failing to do so. The basic ones were pretty easy.
I am wondering what resources I should look at to relearn SQL or maybe datacamp gets better as I progress? Idk. So far it seems to gloss over a lot of concepts but there is a lack of application. Or maybe I’m not very good at this and should just stick to corporate finance :/
