How to prepare for Tableau Interviews
For Tableau interviews, it is needless to say that you should have a good knowledge of Tableau and how to create visualizations in Tableau.
If you go for an interview, there is a chance that companies will talk to multiple candidates before deciding on the right candidate. More than likely, all these candidates will know Tableau, so you should try to stand apart from the rest.
