01
What are Show Me and the automatic mark type in Tableau?
Show Me is a panel that suggests chart types based on the fields you have selected, highlighting valid options such as bar, map, scatter or histogram and stating minimum field requirements. Automatic mark type lets Tableau pick a mark based on the pills, for example line for continuous dates. Both speed up exploration, but experienced analysts often build charts manually for full control.
02
A CSV loads dates as strings like 15-08-2025. How do you convert them?
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.
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.
04
A business user wants a chart where they can switch between Sales, Profit and Quantity. How would you build it?
Create a string parameter with the values Sales, Profit and Quantity. Create a calculated field: CASE [Measure Selector] WHEN 'Sales' THEN SUM([Sales]) WHEN 'Profit' THEN SUM([Profit]) ELSE SUM([Quantity]) END. Use this field on the axis, show the parameter control, and put the parameter in the title so users know which measure they see. Number formatting can be handled with separate calculations if needed.
05
What is the difference between a live connection and an extract?
A live connection sends queries directly to the source database each time the view changes, so data is always current but performance depends on the database. An extract is a compressed snapshot stored in the Hyper format, which is usually faster and works offline, but must be refreshed on a schedule. Teams choose live for real-time needs and extracts for speed or slow sources.
06
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.
07
Build a Pareto chart showing what share of customers drive 80 percent of sales.
Sort customers by sales descending on Columns. Running share of sales:
RUNNING_SUM(SUM([Sales])) / TOTAL(SUM([Sales]))
Running share of customers:
INDEX() / SIZE()
Use a dual axis with bars for sales and a line for running percent, and add a reference line at 0.8.
08
Your Excel source has merged header cells and title rows, and Tableau reads it incorrectly. What do you do?
Turn on Data Interpreter on the data source page, which detects headers, removes title rows and handles sub-tables. Review the interpreter results sheet it produces. If it still fails, clean the file in Excel or Tableau Prep by removing merged cells and keeping one header row. Ask the data owner for a clean, tabular format for future files.
Device layouts let you design separate versions of a dashboard for desktop, tablet and phone within the same dashboard. You can add, remove and rearrange items for each device, and Tableau shows the right layout based on screen size. For Indian field sales teams who check dashboards on mobile, a phone layout with key KPIs stacked vertically is very useful.
10
Write a calculation for profit ratio and a profit flag.
Profit Ratio:
SUM([Profit]) / SUM([Sales])
Profit Flag:
IF SUM([Profit]) > 0 THEN 'Profitable'
ELSEIF SUM([Profit]) = 0 THEN 'Break-even'
ELSE 'Loss'
END
Format Profit Ratio as percentage. Both are aggregate, so they work at any view level.
11
Describe how you work with data engineers on a BI project.
Situation: my dashboard needed customer data that was spread across three systems. Task: get a reliable, single table. Action: I wrote clear requirements with grain, fields and refresh needs, shared sample SQL, and reviewed their view together, testing counts against source systems. Result: they built a curated table, my dashboard became simpler and faster, and we reused the table for two other reports.
12
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.
With no dimension, FIXED computes at the table level, returning grand total sales for the whole data source, after context and data source filters. It is useful for percent of total: SUM([Sales]) / MIN({FIXED : SUM([Sales])}). Since it repeats on every row, wrap it in MIN, MAX or AVG in the view rather than SUM, which would multiply the total.
14
An interviewer asks you to find the highest-selling product in each category. How do you approach it?
Calculate category max: {FIXED [Category] : MAX({FIXED [Category], [Product Name] : SUM([Sales])})}. Then flag: IF {FIXED [Category], [Product Name] : SUM([Sales])} = [Category Max] THEN 'Top' END and filter to Top. A simpler alternative is a RANK table calculation computed along products within each category, filtering rank equal to 1.
15
How does Tableau handle null values in calculations?
Most operations involving a null return null, so [Sales] + null is null. Use ZN to convert null numbers to zero, IFNULL to replace nulls with a value, and ISNULL to test for them. Aggregations such as SUM ignore nulls. In charts, nulls may appear as an indicator at the bottom right, and you can choose to filter, show at default position or hide them.
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.
17
How do you gather requirements before building a dashboard?
Situation: a supply chain team asked for an inventory dashboard without clear details. Task: understand what they needed. Action: I met users to ask which decisions they make, which KPIs and filters matter, refresh frequency and who will use it, then sketched a wireframe and confirmed it. Result: the first version was accepted with only minor changes, saving rework time.
18
How do you ensure your dashboards are actually used after launch?
Situation: an earlier dashboard I built had low usage after launch. Task: improve adoption on the next project. Action: I involved users in design, ran a short training session, added a how-to-use panel, set subscriptions for managers, and checked usage statistics monthly to remove unused views. Result: weekly active users doubled compared with the earlier dashboard, and feedback guided the next release.
19
You get the error cannot mix aggregate and non-aggregate arguments. How do you fix it?
The formula mixes a row-level field with an aggregated one, such as IF [Sales] > AVG([Sales]). Either aggregate everything, for example IF SUM([Sales]) > 1000, or make everything row level. If you need to compare a row with an overall average, use an LOD such as [Sales] > {FIXED : AVG([Sales])}, which returns a row-level value that can be mixed safely.
A context filter is an independent filter that runs before other dimension filters, Top N filters and FIXED LODs. Tableau creates a temporary result set from it, and other filters work on that subset. Use it when Top N should apply within a selection, such as top 10 products within a chosen region. Context filter pills turn grey in the Filters shelf.
21
Your company is migrating from Tableau Server to Tableau Cloud. What would you plan?
Inventory content and usage to retire unused workbooks, map sites, projects, users, groups and permissions, and plan authentication. Set up Tableau Bridge for on-premise data, recreate schedules and subscriptions, and use migration tools to move content. Test critical dashboards for performance and row-level security, plan a pilot, communicate cut-over dates, and keep a rollback plan.
22
Why does filtering on a table calculation behave differently from a normal filter?
Table calculation filters apply at the end of the order of operations, after the calculation, so they hide marks without removing data from the computation. A normal dimension filter removes rows before the calc, changing running totals and ranks. To show only the last three months while keeping a running total from the start, filter with a table calc such as LAST() <= 2.
23
Management wants new versus repeat customers per month. How would you build it?
Create First Purchase Month: {FIXED [Customer ID] : MIN(DATETRUNC('month', [Order Date]))}. Then Customer Type: IF DATETRUNC('month', [Order Date]) = [First Purchase Month] THEN 'New' ELSE 'Repeat' END. Put MONTH(Order Date) on Columns, COUNTD(Customer ID) on Rows and Customer Type on Color. Validate a few customers manually to make sure classification is correct.
24
Describe a time a stakeholder disagreed with your visualisation choice.
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.
25
A client wants dashboards embedded in their internal web portal. How would you approach it?
Use Tableau's embedding API or the Tableau web component to embed views in the portal, with single sign-on such as SAML or connected apps for authentication so users do not log in twice. Ensure users have licences and correct permissions, apply row-level security, set the dashboard size to fit the portal, and use the API to pass filters or parameters from the page.
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.
A dashboard is a collection of sheets, filters, legends, text, images and objects arranged on one canvas so users can see related views together and interact through actions. A story is a sequence of story points, each showing a sheet or dashboard in a particular state, used to present a narrative such as how sales changed and why. Stories suit presentations, dashboards suit monitoring.
Tableau uses exponential smoothing models to forecast continuous time series. It chooses the best model, with or without trend and seasonality, based on the data and shows prediction intervals. You need a continuous date and a measure. Options include forecast length, aggregation level and ignoring the last incomplete period. It suits quick projections, while complex forecasting needs Python or R integration.
29
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.
30
How are LOD expressions different from table calculations?
LOD expressions are computed in the data source as part of the query, so they can be used as dimensions, in filters and inside other calculations. Table calculations run on the aggregated results already in the view, so they depend on the view layout and addressing. LODs are better for fixed levels such as customer totals, while table calcs suit running totals, ranks and differences.
