01
Monthly sales files arrive in a folder every month. How do you avoid manual work each time?
Use a wildcard union on the folder with a pattern such as Sales_*.xlsx so new files are included automatically on refresh. Alternatively, build a Tableau Prep flow with a wildcard input and schedule it with Prep Conductor. Ensure every file has the same column names and types. Use the Path or Table Name field to derive the month if it is not in the data.
02
How do you create a filter action from a map to other sheets?
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.
03
Users say the dashboard takes 30 seconds to load on Server but is fast in Desktop. What do you check?
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.
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.
05
Write a calculation for year-to-date sales compared with last year to date.
Drag Customer Name to Rows and SUM(Sales) to Columns. Drag Customer Name to Filters, open the Top tab, choose By field, Top 10 by Sales Sum. For a flexible version, create an integer parameter and select it instead of the fixed 10, then show the parameter control. If other filters must apply first, add them to context so Top N works on filtered data.
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.
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.
09
Using FIXED with SUM in the view gives a huge inflated number. Why?
FIXED returns a value repeated on every row at the fixed level. If the view is at a finer level, or at the total level, SUM adds the repeated values, multiplying the result. Use MIN, MAX or AVG to bring back the single value, or make sure the view level matches the FIXED dimensions. This is a frequent mistake when using table-level totals.
10
After rearranging the view, your percent of total gives wrong numbers. Why?
The table calc was probably set to Table Across or Table Down, which depends on layout. When fields move between Rows and Columns, the direction changes. Edit the table calculation and set Compute Using to Specific Dimensions with the correct addressing fields. Then the calculation stays correct even if users or developers reorganise the sheet.
11
Tell me about a time you found a data quality issue before stakeholders did.
Situation: while refreshing a weekly revenue dashboard I noticed one region had dropped 60 percent overnight. Task: confirm whether it was real. Action: I checked row counts in the source, found a failed ETL load for two days, informed the data engineering team and added a warning banner. Result: the leadership meeting used corrected figures, and we added an automatic row-count check to the pipeline.
12
A rank changes when the user selects a filter value. The business wants overall rank. What do you do?
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.
13
How do you create a dynamic KPI card with an up or down indicator?
Create the KPI measure and a comparison calculation, for example growth versus last month. Build an indicator calculation: IF [Growth] > 0 THEN '▲' ELSE '▼' END. Use a text mark showing the value, growth and indicator, and colour the indicator using a calculated field for positive and negative. Remove gridlines and borders and place the sheet in a dashboard container.
14
How do you publish a workbook to Tableau Server or Cloud?
Sign in through Server, Publish Workbook in Desktop. Choose the project, name and description, set permissions or inherit from the project, and decide whether to embed credentials or prompt users for data sources. Choose to show sheets as tabs if needed and include external files for extracts. After publishing, set an extract refresh schedule and verify the views in the browser.
15
A manager wants to download dashboard data into Excel but you must protect sensitive fields. What do you do?
Control capabilities through permissions: allow Download Summary Data but deny Download Full Data, or deny downloads entirely for some groups. Remove sensitive fields from the data source or hide them, and apply row-level security so downloaded data is limited to the user's scope. Provide a dedicated crosstab sheet with approved fields for export and document what is allowed.
Put the KPI dimension on Rows and continuous MONTH(Order Date) with SUM(Sales) on a separate column, choose line marks, and set Independent Axis Ranges for each row via Edit Axis. Remove gridlines, axes, headers and borders, and highlight the last point using a calculation such as IF LAST() = 0 THEN SUM([Sales]) END as a dual axis circle.
17
How would you set up row-level security using a user entitlement table?
Create an entitlement table with Username and Region columns, maintained by the business or IT. Relate or join it to the fact table on Region. Create a calculation USERNAME() = [Username] and add it as a data source filter set to True. Publish the data source with embedded credentials and restrict download permissions. Test with View As or user impersonation for each role.
18
What is the Hyper engine and what are its benefits?
Hyper is Tableau's in-memory data engine used for extracts since version 10.5. It is a columnar engine that loads and queries large datasets quickly, supports incremental refresh, and handles billions of rows on good hardware. Extracts in .hyper format improve dashboard speed, reduce load on source databases, and allow aggregation and filtering at extract time to keep the file small.
19
Count customers by the number of orders they placed.
Orders per Customer:
{FIXED [Customer ID] : COUNTD([Order ID])}
Convert it to a dimension and discrete, place it on Columns, and put COUNTD([Customer ID]) on Rows. The chart shows how many customers placed 1, 2, 3 or more orders, a common customer frequency analysis.
A dual axis chart places two measures on the same view with independent or synchronised axes, by dragging the second measure to the right side of the chart or choosing Dual Axis from the pill menu. Use it to compare related measures such as sales bars with profit ratio line. Synchronise axes when units are the same, and label clearly to avoid misleading readers.
21
How do you blend sales data with a targets file in Tableau?
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.
22
How do you create a basic bar chart of sales by region?
Connect to the data source, drag Region to Columns and Sales to Rows. Tableau aggregates Sales with SUM and chooses bars. Sort descending using the toolbar sort icon, drag Region to Color for distinct colours if needed, and drag SUM(Sales) to Label to show values. Rename the sheet and add a meaningful title such as Sales by Region, current year.
A published data source is a data connection with calculations, metadata and refresh schedules stored on Server or Cloud, which many workbooks can connect to. It provides a single version of truth, central refresh, and permissions, and can be certified by data stewards. Changes to calculations update all connected workbooks. It is a key practice for governance in enterprise Tableau.
24
An extract refresh fails every morning on Server. How do you troubleshoot?
Check the background task and job history for the error message. Common causes are expired or changed database passwords, firewall or VPN issues, schema changes like renamed columns, timeout because the query is too large, or Backgrounder overload at peak time. Fix credentials, update the data source, optimise the query or move the schedule. Set up failure email notifications.
25
Tell me about the most impactful dashboard you have built.
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.
26
How do you use a parameter action to let users click a bar and change a reference line?
Create a float parameter, for example Selected Value. Add a reference line using that parameter. Then go to Dashboard, Actions, Add Action, Change Parameter, choose the source sheet, target parameter Selected Value, and source field SUM(Sales), with aggregation set as needed. Clicking a bar updates the parameter, and the reference line moves to compare other bars with it.
27
Build a dimension switcher so users choose Region, Category or Segment.
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.
28
Tell me about a mistake you made in a report and how you handled it.
Situation: I published a dashboard where a percent of total used Table Across and gave wrong numbers after a layout change. Task: fix it and rebuild trust. Action: I informed the stakeholder immediately, corrected the calc with Specific Dimensions, added a validation sheet comparing totals, and re-shared. Result: the issue was fixed within an hour, and I now test calcs after every layout change.
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.
30
Your dashboard has 40 sheets and analysts keep making inconsistent calculations. How would you standardise it?
Publish a certified data source to Server or Cloud with agreed calculated fields, default formats, hierarchies, folders and descriptions. Ask analysts to connect to that source instead of local copies. Maintain a data dictionary, naming conventions and a review checklist before publishing. Remove duplicate calculations from workbooks. This gives one version of truth and makes later changes in one place.
