01

A string calculation CONTAINS([Product], 'phone') misses some rows. Why?

Calculated FieldsMedium
Save to ▾
Show answer
CONTAINS is case-sensitive in many sources, so Phone or PHONE will not match. Use CONTAINS(LOWER([Product]), 'phone') to normalise case. Also trim extra spaces and check for nulls. If you need complex patterns, use REGEXP_MATCH where the data source supports it. Test the result by counting matched rows and reviewing samples.
02

Your dashboard looks perfect on your laptop but broken on the manager's screen. How do you fix it?

Dashboards and Tableau ServerMedium
Save to ▾
Show answer
The dashboard probably uses Automatic or Range size, so objects reflow on different resolutions. Set a fixed size suitable for the audience, such as 1366 by 768 or 1200 by 900, or use Range carefully with tiled containers. Avoid floating objects that overlap. Create a device layout for phones if needed and test on common screen sizes before sharing.
03

What are small multiples and why are they useful?

Charts and Visual DesignEasy
Save to ▾
Show answer
Small multiples are a grid of similar charts that share axes, one for each category, such as a sales line chart per region. They make comparisons easier than one crowded chart with many coloured lines. In Tableau you create them by adding a dimension to Rows or Columns alongside the chart fields, or with index-based calculations for a trellis grid.
04

What is a virtual connection and data policy in Tableau?

Dashboards and Tableau ServerHard
Save to ▾
Show answer
A virtual connection is a shareable, centrally managed access point to database tables, with embedded credentials and optional extracts. A data policy attached to it applies row-level security at the table level using user functions and entitlement tables. Every workbook and data source using the connection inherits the security, so rules are defined once instead of in each data source. It requires Data Management licensing.
05

What are subscriptions and data-driven alerts?

Dashboards and Tableau ServerMedium
Save to ▾
Show answer
Subscriptions email users an image or PDF snapshot of a view or dashboard on a schedule, such as every Monday at 9 AM. Data-driven alerts notify users when a measure crosses a threshold, such as inventory below safety stock, checked when data refreshes. Both help business users who do not open dashboards daily, but too many can cause email fatigue.
06

How do you create a donut chart in Tableau?

Charts and Visual DesignMedium
Save to ▾
Show answer
Create a pie on the first axis using a measure on Angle and a dimension on Color. Put two copies of MIN(0) on Rows, set the second to circle mark, make it smaller and white, and select Dual Axis with synchronised axes. Place a total label on the inner circle. Use donuts only for two to four segments; bar charts are usually clearer.
07

Tell me about the most impactful dashboard you have built.

Dashboards and Tableau ServerMedium
Save to ▾
Show answer
Situation: the operations team tracked delivery delays in spreadsheets updated weekly. Task: give them daily visibility. Action: I built a dashboard on a scheduled extract with delay KPIs, a city map and a drill-down to late orders, and trained the team leads. Result: they spotted delays a day earlier, and late deliveries reduced by about 12 percent over two months.
08

How do you set up an incremental extract refresh?

Data Connections and ModellingMedium
Save to ▾
Show answer
Create an extract from the Data menu, choose Extract Data, and tick Incremental refresh. Select a column whose values always increase, such as Order ID or Load Timestamp. Publish to Server or Cloud and create a schedule for incremental refresh, plus an occasional full refresh. Ensure the source does not update old records, or those changes will be missed.
09

What are the main categories of functions in Tableau calculations?

Calculated FieldsEasy
Save to ▾
Show answer
Tableau offers number functions such as ROUND and ABS, string functions such as LEFT, CONTAINS and SPLIT, date functions such as DATEDIFF, DATEADD and DATETRUNC, type conversion such as STR, INT and DATE, logical functions such as IF, CASE and IIF, aggregate functions such as SUM and COUNTD, user functions such as USERNAME, and table calculation functions such as RUNNING_SUM and RANK.
10

What is the difference between a filter and a parameter?

Filters, Parameters and ActionsEasy
Save to ▾
Show answer
A filter directly restricts data in the view based on field values and can show multiple selections. A parameter is a single value variable that users change, and it affects the view only through calculations or features that reference it. Filters are tied to data fields; parameters are global and can be used across data sources, making them useful for switching measures or dimensions.
11

What types of filters are available in Tableau?

Filters, Parameters and ActionsEasy
Save to ▾
Show answer
Tableau has extract filters, data source filters, context filters, dimension filters, measure filters, table calculation filters and date filters such as relative date, range and individual dates. Filters can be shown as quick filter controls like dropdown, single value list, multiple values list, slider or wildcard match. Each type applies at a different stage in the order of operations.
12

Write a calculation for year-to-date sales compared with last year to date.

Calculated FieldsMedium
Save to ▾
Show answer
YTD Sales: IF YEAR([Order Date]) = YEAR(TODAY()) AND [Order Date] <= TODAY() THEN [Sales] END LYTD Sales: IF YEAR([Order Date]) = YEAR(TODAY()) - 1 AND [Order Date] <= DATEADD('year', -1, TODAY()) THEN [Sales] END Growth: (SUM([YTD Sales]) - SUM([LYTD Sales])) / SUM([LYTD Sales])
13

How do you build a bullet chart for actual versus target?

Charts and Visual DesignMedium
Save to ▾
Show answer
Select Sales and Target with a dimension such as Region, then choose bullet graph from Show Me. Tableau puts Sales as bars and Target as a reference line with distribution bands. If the roles are reversed, right-click the axis and choose Swap Reference Line Fields. Add colour for achieved versus missed using a calculation comparing SUM(Sales) with SUM(Target).
14

What does LOOKUP do and how is it used?

Table CalculationsMedium
Save to ▾
Show answer
LOOKUP(expression, offset) returns the value of an aggregate from another row in the partition, relative to the current row. LOOKUP(SUM([Sales]), -1) returns the previous period, useful for period-over-period difference. Positive offsets look forward. FIRST() and LAST() can be used as offsets to compare every row with the first or last period.
15

What are user functions and how are they used for row-level security?

Calculated FieldsMedium
Save to ▾
Show answer
User functions such as USERNAME, FULLNAME, ISMEMBEROF and USERDOMAIN return details of the person viewing the workbook on Server or Cloud. A calculation like [Manager Email] = USERNAME() or ISMEMBEROF('North Team') can be used as a data source filter set to true. Each user then sees only their rows. This is a common way to implement row-level security in Tableau.
16

Calculate month-over-month percentage growth.

Table CalculationsMedium
Save to ▾
Show answer
MoM Growth: (SUM([Sales]) - LOOKUP(SUM([Sales]), -1)) / ABS(LOOKUP(SUM([Sales]), -1)) Compute along month. The first month returns null because there is no previous value. Format as percentage and colour positive and negative values differently for quick reading.
17

What is the Tableau order of operations?

Tableau FundamentalsMedium
Save to ▾
Show answer
Tableau applies filters and calculations in a fixed sequence: extract filters, data source filters, context filters, then sets, Top N and FIXED LOD, then dimension filters, then INCLUDE and EXCLUDE LOD and blending, then measure filters, then table calculations, totals and reference lines, and finally table calculation filters and trend lines. Knowing this explains why a FIXED calculation ignores a normal dimension filter unless it is added to context.
18

What is the difference between Tableau Server and Tableau Cloud?

Dashboards and Tableau ServerEasy
Save to ▾
Show answer
Tableau Server is self-hosted on the company's own infrastructure or cloud machines, so IT manages installation, upgrades, scaling and security. Tableau Cloud is a fully hosted software-as-a-service platform managed by Tableau, with automatic upgrades. Cloud reaches on-premise data through Tableau Bridge. Companies with strict data residency or customisation needs may prefer Server.
19

How do calculations affect performance, and what are best practices?

Calculated FieldsHard
Save to ▾
Show answer
Row-level calculations on large live sources run in the database for every query, so heavy string operations and nested IFs can be slow. Best practices are to use booleans and integers instead of strings, prefer CASE for fixed lists, move complex logic to the database or extract, materialise calculations in extracts, avoid unnecessary COUNTD, and keep LODs and table calculations simple.
20

What is a union and when do you use it?

Data Connections and ModellingMedium
Save to ▾
Show answer
A union stacks tables with the same structure on top of each other, adding rows rather than columns. It is used for monthly or regional files such as Sales_Jan, Sales_Feb and Sales_Mar. Tableau supports manual unions and wildcard unions that pick up files or sheets matching a name pattern, and adds Table Name and Path fields to identify the source of each row.
21

Users complain that a dashboard with 10 dropdown filters is slow. How do you improve it?

Filters, Parameters and ActionsMedium
Save to ▾
Show answer
Measure first with performance recording. Reduce the number of quick filters and replace some with dashboard filter actions. Change Only Relevant Values to All Values in Database where cascading is not needed. Add an Apply button to multi-select filters, convert high-cardinality filters to wildcard search, and move fixed restrictions to data source filters. Re-test after changes.
22

What are dynamic parameters?

Filters, Parameters and ActionsMedium
Save to ▾
Show answer
Since version 2020.1, parameters can refresh their list of values or current value from a field when the workbook opens. For example, a date parameter can default to the latest date in the data using a calculation like MAX([Order Date]), and a list can pull current region names. This removes manual maintenance when new values appear in data.
23

A CSV loads dates as strings like 15-08-2025. How do you convert them?

Calculated FieldsMedium
Save to ▾
Show answer
Try changing the data type to Date first; Tableau may parse it automatically. If not, use DATEPARSE with the pattern: DATEPARSE('dd-MM-yyyy', [Date String]). For extracts and most databases this works reliably. Alternatively use MAKEDATE with INT of SPLIT parts. Then check for nulls, which indicate rows with a different format that need cleaning.
24

Sales team wants year over year growth for each month on a single chart. How do you build it?

Table CalculationsMedium
Save to ▾
Show answer
Place MONTH(Order Date) discrete on Columns and YEAR(Order Date) on Color with SUM(Sales) on Rows. Add a quick table calculation Percent Difference, compute using Year, relative to previous. Each month now shows growth versus the same month last year. Alternatively calculate with LOOKUP(SUM([Sales]), -1) partitioned by month and addressed by year.
25

How do you blend sales data with a targets file in Tableau?

Data Connections and ModellingMedium
Save to ▾
Show answer
Connect to both sources. Build the view with the primary source, for example Region and Month from sales. Switch to the targets source in the Data pane, check the link icon next to Region and Month so they are active linking fields, then drag Target onto the view. Tableau aggregates targets to those fields. Make sure the linking field names and values match exactly.
26

What options does the Analytics pane provide?

Charts and Visual DesignMedium
Save to ▾
Show answer
The Analytics pane offers summarise options such as constant line, average line, median with quartiles, box plot and totals, model options such as average with confidence interval, trend line, forecast and clustering, and custom reference lines, bands, distributions and box plots. Dragging an item onto the view adds it at table, pane or cell scope.
27

Are LOD expressions dimensions or measures?

LOD ExpressionsMedium
Save to ▾
Show answer
FIXED LODs with dimensions return row-level values that can be used as dimensions, for example a customer's first order year used for cohort analysis. Tableau puts them in measures by default when the result is numeric, but you can convert them to dimension. INCLUDE and EXCLUDE results are measures because they depend on the view. Converting FIXED to a dimension is common for bucketing.
28

Tell me about a time your analysis changed a business decision.

LOD ExpressionsMedium
Save to ▾
Show answer
Situation: the marketing team planned to increase spend on a segment they believed was growing. Task: check the trend before budget approval. Action: I built a cohort analysis using FIXED first purchase date and found repeat purchase rates in that segment had fallen for three quarters. Result: they shifted part of the budget to retention campaigns, and repeat purchases improved the next quarter.
29

Your percent of total changes when a user filters Category. The business wants it to stay fixed. What do you do?

LOD ExpressionsMedium
Save to ▾
Show answer
If you used a quick table calculation, the total is computed on the filtered view, so it changes. Replace it with a FIXED LOD for the total, which ignores dimension filters, or use EXCLUDE for the filtered dimension. Make sure any filters that should affect the total are added to context. Test with and without filters and document the behaviour.
30

What is the difference between discrete and continuous fields?

Tableau FundamentalsEasy
Save to ▾
Show answer
Discrete fields (blue pills) contain distinct, separate values and create headers or labels in the view. Continuous fields (green pills) form an unbroken range and create axes. Both dimensions and measures can be either. For example, YEAR(Order Date) as discrete shows separate year headers, while continuous dates draw a single timeline axis. Choosing correctly changes how the chart looks and how filters behave.
31

A live connection dashboard on a large database is very slow. What options would you evaluate?

Data Connections and ModellingHard
Save to ▾
Show answer
Check the performance recording to see slow queries. Options include switching to an extract with aggregation and extract filters, adding database indexes or materialised views, removing custom SQL, enabling referential integrity assumptions, reducing the number of marks and quick filters, and using context filters wisely. If real-time is not required, a scheduled extract usually gives the biggest improvement.
32

How do you improve dashboard performance in Tableau?

Dashboards and Tableau ServerMedium
Save to ▾
Show answer
Use the performance recorder to find slow queries and rendering. Use extracts with only needed fields and rows, aggregate data, reduce marks and sheets, limit quick filters and relevant values, prefer integer and boolean calculations, avoid heavy custom SQL, use fixed dashboard size for caching, and hide unused fields. Workbook Optimizer in Desktop also suggests improvements based on best practices.
33

Calculate average sales per customer for each region.

LOD ExpressionsMedium
Save to ▾
Show answer
Use INCLUDE to compute at customer level inside each region: AVG({INCLUDE [Customer ID] : SUM([Sales])}) Place Region on Rows. Tableau sums sales per customer within each region, then averages those totals. Without INCLUDE, AVG([Sales]) would give average per order line, which answers a different question.
34

What is Tableau Prep Builder used for?

Data Connections and ModellingMedium
Save to ▾
Show answer
Tableau Prep Builder is a visual tool for cleaning, combining and shaping data before analysis. A flow includes input, clean, aggregate, pivot, join, union and output steps, and shows data profiles to spot nulls and outliers. Output can be a hyper extract, CSV, or published data source. With Prep Conductor on Server or Cloud, flows can run on schedule as a repeatable pipeline.
35

After joining Orders with Returns, total sales went up. What happened?

Data Connections and ModellingMedium
Save to ▾
Show answer
The join type or grain caused duplication. If Returns has multiple rows per order, an inner or left join repeats each order line, so SUM(Sales) inflates. Fix it by using a relationship instead of a join, aggregating Returns to order level before joining, or using an LOD to deduplicate. Always check row counts before and after a join to catch this problem early.
36

What is custom SQL in Tableau and what are its drawbacks?

Data Connections and ModellingHard
Save to ▾
Show answer
Custom SQL lets you write your own query as a data source, useful for complex logic or pre-aggregation. The drawback is performance: Tableau wraps it as a subquery, so the database may not optimise filters well, and it blocks some features such as join culling. It is also harder to maintain. Prefer database views or relationships and use custom SQL only when needed.
