If you are a fresher and have doubts about preparing for your Tableau interview, go through the following basic Tableau interview questions and answers to ace your interview.
This is a frequently asked Tableau interview question that you must keep at your fingertips. Different Tableau products include:
BI tools and Tableau differ in terms of efficiency and speed. The other differences between these two are:
When you display the measures and dimensions in an aggregated form, it is known as an aggregation of data. Whereas when you display every data field separately, it is known as disaggregation of data. You must know the common aggregate functions available in the Tableau tool, which are as follows:
The supported file extensions in Tableau are:
The supported data types in Tableau are:
You need to load testing in Tableau to understand the server’s capacity concerning its environment, workload, data, and use. You should conduct load testing at least 3 to 4 times a year. That is because workload, data, usage upgrade, or content authoring change whenever a new user joins in.
You must know that Tabjolt was created by Tableau to conduct point and run load and performance testing, particularly in Tableau servers. The features of Tabjolt are:
The differences between QlikView and Tableau are:
A few of the various reasons to use Tableau are:
If you use a filter in Tableau, it will restrict unnecessary data and will show the exact data you want. The three filters you can use in Tableau are Quick, Datasource and Context.
To remove the show-all option from a Tableau auto-filter, you must do the following: Right-click on Filter > Customize > Uncheck the show-all option.
It is not possible to join more than 32 tables together in Tableau. It means you can join a maximum of 32 tables in Tableau.
With the help of a treemap, you can illustrate hierarchical data. It is a powerful tool used to visualize a part or whole relationship between different data. On the other hand, with the help of a treemap, you can compare categories using size and color and two various measures.
You should not miss these ‘Tableau Interview Questions for Experienced’ even if you are a fresher. You must cover every corner of Tableau while preparing Tableau interview questions to create a long-lasting impression on the interviewer.
To view SQL, you need to go to C:/Users/MyDocuments/MyTableau repository. If you have a live connection to the data sources, you need to check the log.txt and tabprotosrv.txt files. The tabprotosrv.txt files often show detailed information about queries.
Firstly, you need to create a particular time to develop and extract the data source and publish it on the server. Before publishing, click on ‘scheduling and authentication and select the schedule option from the drop-down and publish it.
After doing this, you have to publish data sources and assign the schedule. You must know that this schedule will automatically run for the scheduled time, and the workbook will get refreshed automatically and regularly.
In Tableau 8.0, you will get new visualizations, such as bubble charts, treemaps, and box and whisker plots. You can copy worksheets directly from one to another. Tableau 8.0 introduces the R script as well.
You must follow the steps given below to create filled maps:
Using Index, you can mainly deal with a record’s physical location. You can assign incremental numbers according to the record’s physical order. Whereas in Rank, you can deal with the record’s value. You must know that the highest value gets the highest rank, and the lowest value gets the lower rank.
Tableau data extracts are screenshots of data optimized for aggregation and loaded into system memory. This is done to recall for visualization quickly. For example, real-time decisions need to be made when hospitals monitor incoming patients based on their physical condition.
Whereas by using the live connection, you get real-time updates. Tableau does not reflect any changes made in the source in a live connection. For example, hospitals need to see patients’ health based on their weekly/monthly reports.
The function Left(3, “Tableau”) will return an error as the syntax is incorrect. It should be Left(“Tableau”, 3). You should know that Left returns a specific number of characters from the start of the string. If the syntax were correct, the result would be ‘Tab.’
You must use a level of detail expression to run complex queries involving many dimensions at the data source. For example, suppose you want to look at the colors of particular furniture in furniture-related data. In that case, you must use LOD to eliminate other factors, such as size, date of manufacturing, or any additional related information.
You should prepare these sample Tableau interview questions along with the above-mentioned Tableau interview questions and answers to uplevel your preparedness.
