While on an interview process with a company for a Data Analyst role I was asked to do an SQL test. The employer provided me with a document with some questions and a few CSV files with tables.
In the past I did very well on HackerRank tests and I have completed the entire SQL track on Codeacademy. After browsing the internet for hours, at the end I turned down the opportunity to participate because although I knew how to perform the analysis, I didn´t know which platform I could use to perform the querying.
What’s a good platform, database to use in this situations? Any tutorial, guides you can recommend?
Thanks a lot in advance
