Tableau Technical Interview Questions and Answers
Hello Everyone,
After the first 5 most frequently asked Tableau interview questions,
Link the first blog……
Here is my next blog to answer the next five top interview questions.
These interview questions are mostly asked in the technical round of interview of the tableau.
Questions which I have answered in this video:
- What is the difference between a tree map and heat map?
- A heat map can be used for comparing categories with color and size. With heat maps, you can compare two different measures together.
- A tree map also does the same except it is considered a very powerful visualization as it can be used for illustrating hierarchical data and part-to-whole relationships.
2. Name the components of a Dashboard.
Horizontal — Horizontal layout containers allow the designer to group worksheets and dashboard components left to right across your page and edit the height of all elements at once.
Vertical — Vertical containers allow the user to group worksheets and dashboard components top to bottom down your page and edit the width of all elements at once.
Text — All textual fields.
Image Extract — A Tableau workbook is in XML format. In order to extracts images, Tableau applies some codes to extract an image which can be stored in XML.
Web [URL ACTION] — A URL action is a hyperlink that points to a Web page, file, or other web-based resource outside of Tableau. You can use URL actions to link to more information about your data that may be hosted outside of your data source. To make the link relevant to your data, you can substitute field values of a selection into the URL as parameters.
3. What is the difference between joining and blending in Tableau?
Joining term is used when you are combining data from the same source, for example, worksheet in an Excel file or tables in Oracle database
While blending requires two completely defined data sources in your report.
4. What is TDE file?
TDE is a Tableau desktop file that contains a .tde extension. It refers to the file that contains data extracted from external sources like MS Excel, MS Access or CSV file.
5. What is the difference between Discrete and continuous?
Discrete data roles are values that are counted as distinct and separate and can only take individual values within a range.
Continuous data roles are used to measure continuous data and can take on any value within a finite or infinite interval.
