01
What are the Compute Using options such as Table Across and Pane Down?
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.
02
What is the difference between IF, IIF and CASE in Tableau?
IF supports multiple conditions with ELSEIF and complex logical tests. IIF is a compact form taking a test, a true value, a false value and an optional unknown value for nulls. CASE compares one expression against exact values and is easier to read for many fixed options, such as parameter selections. CASE cannot test ranges like Sales greater than 1000, so use IF for that.
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.
A parameter is a user-controlled variable, such as a number, date or string, that is not tied to the data. It does nothing alone; you reference it in calculations, filters, reference lines, Top N or bins. Examples are a measure switcher, a what-if discount rate, or a dynamic Top N. Parameters can be shown as dropdowns, sliders or type-in fields.
05
What is the difference between discrete and continuous fields?
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.
06
What are the main categories of functions in Tableau calculations?
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.
Create a set on Category. Build a calculation: IF [Category Set] THEN [Sub-Category] ELSE '' END, and place Category and this calculation on Rows. Add a set action on select that assigns values to Category Set and removes them when cleared. Clicking a category expands only its sub-categories, creating an asymmetric drill down that standard hierarchies cannot do.
08
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.
09
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.
10
Users complain that a dashboard with 10 dropdown filters is slow. How do you improve it?
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.
Show and hide buttons let users collapse or expand a floating container, such as a filter panel or help text, by clicking a button. They save space on crowded dashboards and keep the main view clean. You enable it from the container menu with Add Show/Hide Button, and style it with images or text. They also work well for mobile layouts.
12
Your manager says the dashboard total does not match the Excel total. How do you investigate?
First compare filters, date ranges and data refresh time between both sources. Check the aggregation used, for example SUM versus AVG, and whether joins have duplicated rows, which inflates totals. Use View Data to inspect underlying rows and COUNT the records. Check null handling and whether Excel has hidden rows or manual adjustments. Document the cause and fix it at the data source level.
13
Sales team wants year over year growth for each month on a single chart. How do you build it?
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.
14
What do addressing and partitioning mean in table calculations?
Addressing fields define the direction the calculation moves along, such as across months. Partitioning fields define the groups where the calculation restarts, such as each region. In Compute Using, checked dimensions are addressing and unchecked ones are partitioning. For a running total of sales by month restarting each year, month is addressing and year is partitioning.
15
What does aggregation mean in Tableau and how can you turn it off?
Tableau aggregates measures to the view level, using SUM, AVG, MIN, MAX, COUNT, COUNTD, MEDIAN and others. Aggregation can be changed per pill from its dropdown. To see every row, you can uncheck Aggregate Measures in the Analysis menu, which plots disaggregated rows, useful for scatter plots of raw records. For large data it can create many marks and slow the view.
16
A stakeholder says the dashboard is too crowded. How do you redesign it?
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.
17
What are sites, projects and permissions on Tableau Server?
A site is an isolated tenant with its own users, content and settings. Projects are folders within a site that hold workbooks, data sources and flows, and can be nested. Permissions are set on projects and content for users and groups, using capabilities such as view, download, web edit and publish. Locking project permissions keeps security consistent for all content inside.
Tableau supports inner, left, right and full outer joins in the physical layer. Inner keeps matching rows only, left keeps all rows from the left table, right keeps all rows from the right, and full outer keeps everything with nulls where no match exists. You can also create join calculations when keys need transformation, such as trimming or changing case, before matching.
19
How do you build a dynamic Top 10 customers chart?
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.
20
What is the difference between FIXED, INCLUDE and EXCLUDE?
FIXED computes at exactly the listed dimensions, regardless of the view. INCLUDE computes at the view level plus extra dimensions, then re-aggregates, for example average sales per customer per region. EXCLUDE removes dimensions from the view level, for example regional total shown against each state. FIXED ignores dimension filters unless in context, while INCLUDE and EXCLUDE respect them.
21
What other Tableau file types should an analyst know?
Common types are .tds (data source definition with connection and metadata), .tdsx (packaged data source with extract), .hyper (extract file), .tfl and .tflx (Tableau Prep flows), .tbm (bookmark of a single sheet) and .tps (preferences for custom colour palettes). Knowing them helps when publishing reusable data sources, sharing flows, or troubleshooting why a colleague cannot open a workbook.
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.
INDEX returns the position of the current row in the partition starting from 1. FIRST returns the offset from the current row to the first row, so it is 0 on the first row and negative afterwards. LAST returns the offset to the last row, 0 on the last row. SIZE returns the number of rows in the partition. They are used for filtering, labelling and custom calculations.
24
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.
25
How do you create a navigation menu between multiple dashboards?
Add Navigation objects or buttons from the Objects pane, set each to go to a target dashboard, and style them with text or images. Place them in a horizontal container at the top of each dashboard for consistency. Use Go to Sheet actions for drill-through from charts. Hide sheets and use Show Sheets as Tabs off when publishing, so users rely on the custom menu.
26
How do you build a line chart showing monthly sales trend?
Drag Order Date to Columns, right-click and choose continuous MONTH. Drag Sales to Rows; Tableau draws a line. Add Category to Color for multiple lines, enable markers from Color options, and add a trend line from the Analytics pane if needed. Format the axis, add a title and tooltip, and check that the latest incomplete month is labelled or excluded.
27
After joining Orders with Returns, total sales went up. What happened?
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.
28
Why do you want to work as a Tableau developer or BI analyst?
Situation: during my final-year project I had sales data in spreadsheets that nobody could read quickly. Task: I wanted to make the trends obvious. Action: I learned Tableau, built a dashboard with KPIs, trends and filters, and presented it to faculty. Result: decisions took minutes instead of hours. I enjoy turning data into decisions, and a BI role lets me do that daily while growing in SQL and analytics.
29
Tell me about a time you explained a complex chart to a non-technical stakeholder.
Situation: a regional head could not understand a scatter plot of discount versus profit. Task: help him act on it. Action: I replaced jargon with a simple story, highlighted the quadrant of loss-making high-discount orders, added a clear title and tooltip, and walked through two examples. Result: he reduced discounts above 30 percent in two regions, and margins improved the next quarter.
Site roles define the maximum capabilities a user can have. Creator users can connect to data, build in Desktop and Prep and publish. Explorer users can explore and web edit existing data sources, with Explorer (can publish) allowing publishing. Viewer users can view and interact with dashboards. Site Administrator roles manage users and content. Permissions on content further restrict what each user can do.
