01

What are quick table calculations?

Table CalculationsEasy
Save to ▾
Show answer
Quick table calculations are ready-made table calcs available from a measure pill's dropdown: running total, difference, percent difference, percent of total, rank, percentile, moving average, YTD total, compound growth rate, year over year growth and YTD growth. They are fast to apply and can be edited later to change addressing or turned into a calculated field by dragging the pill to the Data pane.
02

How do you create a hierarchy and a group from the Data pane?

Tableau FundamentalsMedium
Save to ▾
Show answer
For a hierarchy, drag Sub-Category onto Category in the Data pane and name it, then drag Product below Sub-Category. For a group, right-click a dimension, choose Create, then Group, select members with Ctrl, and click Group, renaming it. Optionally tick Include Other to bucket remaining members. Both appear as new fields and can be used on any sheet.
03

What are the important date functions in Tableau?

Calculated FieldsMedium
Save to ▾
Show answer
DATEPART returns an integer part of a date such as month number. DATENAME returns the name, such as March. DATETRUNC truncates to a level, giving a date such as the first of the month. DATEADD adds intervals, DATEDIFF computes the difference between two dates in a unit, MAKEDATE builds a date, and TODAY and NOW return the current date and time.
04

What is the difference between bins and histograms in Tableau?

Tableau FundamentalsMedium
Save to ▾
Show answer
A bin is a dimension created from a continuous measure by splitting values into equal-sized ranges, for example ages in buckets of 10. A histogram is the chart that counts records in each bin. Tableau can create both automatically through Show Me. You can choose bin size manually or tie it to a parameter so users change bucket width interactively.
05

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.
06

What are reference lines, bands and distributions?

Charts and Visual DesignMedium
Save to ▾
Show answer
Reference lines mark a constant, average, median or parameter value across an axis, such as a target. Reference bands shade a range between two values, such as acceptable delivery time. Distributions show percentiles, quantiles or standard deviations. They are added from the Analytics pane or by right-clicking an axis, and can be computed per table, pane or cell.
07

Build a dimension switcher so users choose Region, Category or Segment.

Filters, Parameters and ActionsMedium
Save to ▾
Show answer
Create a string parameter Dimension Choice with values Region, Category and Segment. Then: Selected Dimension: CASE [Dimension Choice] WHEN 'Region' THEN [Region] WHEN 'Category' THEN [Category] ELSE [Segment] END Put Selected Dimension on Rows and show the parameter control.
08

Users say the dashboard takes 30 seconds to load on Server but is fast in Desktop. What do you check?

Dashboards and Tableau ServerMedium
Save to ▾
Show answer
Compare data connection, since Server may use a live connection through a slower network or different credentials. Record performance on Server using the performance recording parameter. Check concurrent load, VizQL and cache settings, the number of quick filters and marks, and whether extracts are refreshing at the same time. Ask the Server admin for resource usage and background job schedules.
09

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.
10

What is the difference between joining, blending and relationships?

Data Connections and ModellingMedium
Save to ▾
Show answer
Joins merge tables at row level before analysis and can duplicate values. Blending queries each source separately, aggregates the secondary to the linking fields, and combines results per sheet, so it works across sources but has limitations such as no COUNTD from secondary in some cases. Relationships define flexible links and let Tableau choose joins per view while keeping each table's grain.
11

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.
12

Extract the first name from a full name field.

Calculated FieldsMedium
Save to ▾
Show answer
Using SPLIT: SPLIT([Customer Name], ' ', 1) Using FIND and LEFT: LEFT([Customer Name], FIND([Customer Name], ' ') - 1) Trim spaces first if data is messy: SPLIT(TRIM([Customer Name]), ' ', 1) SPLIT is simpler, while the second method shows string function skills.
13

A Snowflake or BigQuery live connection is costing a lot due to many queries. How would you reduce it?

Data Connections and ModellingHard
Save to ▾
Show answer
Use extracts where real-time data is not needed, schedule refreshes outside peak hours, and aggregate extracts to required grain. Reduce quick filters with relevant values, limit dashboards that auto-refresh, and use published data sources so caching is shared. Work with data engineers on materialised or clustered tables. Monitor query history and cost per dashboard to target the worst offenders.
14

How do you create a filter action from a map to other sheets?

Filters, Parameters and ActionsMedium
Save to ▾
Show answer
Go to Dashboard, Actions, Add Action, Filter. Choose the map as source sheet, select the target sheets, set run on Select, and choose what happens when clearing the selection, such as Show all values. Under Filter, choose Selected Fields and map State to State. Test by clicking a state and checking that the bar and trend charts update.
15

What is the difference between a heat map, highlight table and treemap?

Charts and Visual DesignEasy
Save to ▾
Show answer
A highlight table is a text table with cells coloured by a measure, good for showing exact values with patterns. A heat map uses square marks sized or coloured to show density across two dimensions. A treemap shows hierarchical part-to-whole data as nested rectangles sized by one measure and coloured by another. Treemaps suit many categories but make precise comparison harder.
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 data blending and when would you use it?

Data Connections and ModellingMedium
Save to ▾
Show answer
Data blending combines data from two separate data sources on a sheet using linking fields, with one primary and one or more secondary sources. Secondary data is aggregated to the linking level and then joined like a left join. Use it when data lives in different systems and cannot be joined, such as sales in a database and targets in Excel. Relationships have replaced many blending use cases.
18

What is meant by granularity or level of detail of a view?

Tableau FundamentalsMedium
Save to ▾
Show answer
The level of detail of a view is the combination of dimensions placed on Rows, Columns and the Marks card. Each unique combination produces one mark. If only Region is in the view, Sales is summed per region; adding Category on Detail splits each region into category marks. Understanding view granularity is the foundation for LOD expressions and for explaining why numbers change when fields are added.
19

How do you choose the right chart type for data?

Charts and Visual DesignEasy
Save to ▾
Show answer
Choose by the question: comparison of categories uses bar charts, trends over time use line charts, part to whole uses stacked bars or treemaps with few categories, relationships between two measures use scatter plots, distributions use histograms or box plots, and geography uses maps. Keep charts simple and avoid pie charts with many slices, 3D effects or dual axes that confuse readers.
20

How do you build a waterfall chart showing profit build-up by sub-category?

Charts and Visual DesignHard
Save to ▾
Show answer
Put Sub-Category on Columns and SUM(Profit) on Rows, add a Running Total quick table calc, and change mark type to Gantt Bar. Create a calculation -SUM([Profit]) and put it on Size so each bar extends from the previous total. Colour by profit sign and enable Show Row Grand Totals to display the final bar.
21

What is the difference between full and incremental extract refresh?

Data Connections and ModellingMedium
Save to ▾
Show answer
A full refresh rebuilds the entire extract from the source, guaranteeing accuracy but taking longer. An incremental refresh adds only new rows based on a column such as an increasing ID or a date, which is fast but does not capture updates or deletes to old rows. Teams often schedule incremental refreshes daily and a full refresh weekly to keep data correct.
22

Describe a time you had to learn a new Tableau feature quickly for a project.

Calculated FieldsMedium
Save to ▾
Show answer
Situation: a client needed a what-if pricing dashboard in one week. Task: I had not used parameter actions before. Action: I studied official help pages, built a small prototype on sample data, and asked a senior to review it before applying it to real data. Result: the dashboard launched on time and the client used it in a pricing review meeting.
23

What are dashboard actions in Tableau?

Filters, Parameters and ActionsEasy
Save to ▾
Show answer
Dashboard actions add interactivity. Filter actions filter target sheets based on a selection, highlight actions emphasise related marks, URL actions open a web page with field values, Go to Sheet actions navigate, parameter actions change a parameter value by clicking, and set actions change set membership. Actions can trigger on hover, select or menu, giving users guided exploration.
24

How do you show a dynamic title that reflects the selected filter?

Filters, Parameters and ActionsMedium
Save to ▾
Show answer
Double-click the sheet title and use Insert to add fields or parameters, for example Sales for <Region> in <Parameters.Year>. For multiple selected values, the title shows All or the value list; for cleaner text, create a calculation that returns the selection or All, using a FIXED or table calc approach. Dynamic titles reduce confusion during presentations.
25

Show each state's sales compared with its region's total.

LOD ExpressionsMedium
Save to ▾
Show answer
Region Sales: {EXCLUDE [State] : SUM([Sales])} Share of Region: SUM([Sales]) / SUM([Region Sales]) With Region and State in the view, EXCLUDE removes State so each row shows the regional total. Alternatively {FIXED [Region] : SUM([Sales])} works but ignores dimension filters.
26

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.
27

A rank changes when the user selects a filter value. The business wants overall rank. What do you do?

Table CalculationsMedium
Save to ▾
Show answer
Normal filters remove rows before the rank is computed, so rank recalculates on the filtered set. Either replace the filter with a table calculation filter such as LOOKUP(MIN([Product]), 0), which hides rows after ranking, or compute rank with an LOD-based approach. Explain both behaviours to the user and confirm which rank they actually need.
28

Describe a time a stakeholder disagreed with your visualisation choice.

Charts and Visual DesignMedium
Save to ▾
Show answer
Situation: a sales head wanted a 3D pie chart for regional share. Task: deliver what he needed while keeping the chart readable. Action: I made both versions, showed how the bar chart made the rank and gap between regions obvious, and kept his preferred colours. Result: he chose the bar chart for the monthly review and asked me to apply the same style to other reports.
29

What are the Compute Using options such as Table Across and Pane Down?

Table CalculationsMedium
Save to ▾
Show answer
Table Across computes left to right across the whole table, Table Down top to bottom, Table Across then Down moves across then wraps, Pane options restrict the calculation to each pane, Cell computes within a single cell, and Specific Dimensions lets you tick exact addressing fields. Specific Dimensions is the most reliable because it does not change when the layout is rearranged.
30

What is a calculated field in Tableau?

Calculated FieldsEasy
Save to ▾
Show answer
A calculated field is a new field created from existing data using Tableau's formula language. It can perform arithmetic, string manipulation, date logic, conditional logic, aggregations, LOD expressions or table calculations. Calculations are saved in the data source of the workbook and can be reused on any sheet. Examples are profit ratio, customer age group, or a flag for late deliveries.
31

A stakeholder says the dashboard is too crowded. How do you redesign it?

Dashboards and Tableau ServerEasy
Save to ▾
Show answer
Ask which questions they need answered first. Follow a top-down layout: KPIs at the top, main trend and comparison charts in the middle, details at the bottom or on drill-through. Remove decorative elements, reduce colours, align objects in containers, use white space and consistent fonts, and move secondary filters into a collapsible panel using show and hide buttons.
32

A CXO wants a dashboard that updates every 15 minutes during a sale event. How do you design it?

Dashboards and Tableau ServerHard
Save to ▾
Show answer
Assess whether the source supports frequent queries. Options are a live connection to an optimised warehouse table with pre-aggregated data, or frequent incremental extract refreshes if allowed. Keep the dashboard light with few marks, headline KPIs and a trend, and enable auto-refresh behaviour or ask users to refresh. Load test before the event and monitor during it.
33

An Employee ID field is being summed in your view. What do you do?

Tableau FundamentalsMedium
Save to ▾
Show answer
Employee ID is numeric, so Tableau classified it as a measure. Right-click it in the Data pane and choose Convert to Dimension, and optionally Convert to Discrete. Now it acts as a label rather than an aggregated number. If you need the number of employees, use COUNTD(Employee ID) instead of SUM. Fixing default properties early avoids wrong numbers across all sheets.
34

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.
35

Show each product's rank within its category.

Table CalculationsMedium
Save to ▾
Show answer
Rank: RANK(SUM([Sales]), 'desc') Place Category and Product on Rows. In Edit Table Calculation choose Specific Dimensions, tick Product only so the rank restarts for each category. Add a filter on the rank calculation, set to at most 5, to show the top five products in every category.
36

What is a URL action and give an example?

Filters, Parameters and ActionsMedium
Save to ▾
Show answer
A URL action opens a web page, a file or an email link using field values from the selected mark. For example, clicking an order can open the order details page in an internal system with the Order ID passed in the URL, or clicking a company can open a search. URL actions can open in a new tab or inside a web page object in the dashboard.
