About the managerial round round

The managerial round is usually with a hiring manager or team lead. It mixes real-work scenarios, prioritisation and stakeholder questions with behavioural questions about ownership, conflict and learning.

Tips for the managerial round round

  • Use the STAR format for every story: Situation, Task, Action, Result.
  • Show trade-offs: what you chose, what you gave up and why.
  • Be honest about mistakes and focus on what you changed afterwards.
  • Ask the manager about team goals and how success is measured in the role.

01

How are LOD expressions different from table calculations?

LOD ExpressionsMedium
Save to ▾
Show answer
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.
02

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.
03

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.
04

Tell me about a time you pushed back on a stakeholder's request.

Dashboards and Tableau ServerHard
Save to ▾
Show answer
Situation: a sales director asked me to remove returns from revenue on the leadership dashboard to show higher growth. Task: keep reporting accurate while meeting his need. Action: I explained the impact on other reports, showed gross and net side by side with clear labels, and escalated the definition to finance for a final decision. Result: finance confirmed net revenue, and the director accepted it.
05

Monthly sales files arrive in a folder every month. How do you avoid manual work each time?

Data Connections and ModellingMedium
Save to ▾
Show answer
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.
06

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.
07

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.
08

What are the performance impacts of quick filters?

Filters, Parameters and ActionsHard
Save to ▾
Show answer
Every quick filter with Only Relevant Values sends extra queries to fetch domain values, and multiple value lists on high-cardinality fields like Customer Name are expensive. Many filters also slow rendering. Use action filters from charts instead, use Apply buttons, prefer All Values in Database for large lists, filter dates with ranges, and push data source filters for fixed restrictions.
09

A client wants dashboards embedded in their internal web portal. How would you approach it?

Dashboards and Tableau ServerMedium
Save to ▾
Show answer
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.

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.
11

Leadership wants one dashboard that shows 25 KPIs. How do you design it without clutter?

Charts and Visual DesignHard
Save to ▾
Show answer
Clarify the top five decisions the dashboard should support. Show 4 to 6 headline KPIs as cards at the top, group the others into themed sections or separate tabs, and use drill-down actions to detailed views. Use consistent formatting, small multiples and sparklines for trends. Prototype with users, gather feedback, and remove KPIs that nobody uses.
12

How do you create a sparkline in a KPI table?

Charts and Visual DesignHard
Save to ▾
Show answer
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.
13

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.
14

You notice hundreds of duplicate workbooks and data sources on Server. How would you clean up governance?

Dashboards and Tableau ServerHard
Save to ▾
Show answer
Use admin views and usage statistics to find stale or duplicate content. Agree a governance model with owners: certified data sources, project structure by department, naming standards, and a sandbox project for drafts. Archive content not viewed in 90 days after notifying owners, lock project permissions, and set a monthly review. This reduces confusion and Server load.
15

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.
16

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.
17

How do you implement drill down with set actions?

Filters, Parameters and ActionsHard
Save to ▾
Show answer
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.
18

Tell me about a time you found a data quality issue before stakeholders did.

Data Connections and ModellingMedium
Save to ▾
Show answer
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.
19

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.
20

Your company is migrating from Tableau Server to Tableau Cloud. What would you plan?

Dashboards and Tableau ServerHard
Save to ▾
Show answer
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.
21

Different analysts calculate active customer differently. How do you resolve it?

Calculated FieldsHard
Save to ▾
Show answer
Agree on a business definition with stakeholders, such as a customer with at least one order in the last 90 days, and document it. Create one calculated field using an LOD on the last order date, add it to a certified published data source with a description, and deprecate old versions. Communicate the change and compare old and new numbers so users understand the difference.
22

A workbook with many nested table calculations is slow in the browser. How do you approach it?

Table CalculationsHard
Save to ▾
Show answer
Table calcs run on the result set, so large numbers of marks make them slow. Reduce marks by aggregating to the needed level, filter data earlier with context or data source filters, replace some table calcs with LODs or database-side calculations, and avoid nested WINDOW functions over thousands of rows. Use a performance recording to confirm computing layouts and query time.
23

How do you create a navigation menu between multiple dashboards?

Dashboards and Tableau ServerMedium
Save to ▾
Show answer
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.
24

A stakeholder asks for a pie chart with 15 categories. What do you suggest?

Charts and Visual DesignMedium
Save to ▾
Show answer
Explain that a pie with 15 slices is hard to read because people compare angles poorly. Suggest a sorted horizontal bar chart showing values and percentages, which makes ranking clear, or group the smallest categories into Others and show the top five. If they still want a pie, limit it to a few slices. Offer both and let them choose based on readability.
25

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.
26

A business user wants a what-if analysis for price increase on profit. How would you build it?

Filters, Parameters and ActionsMedium
Save to ▾
Show answer
Create a float parameter Price Change with a slider range of -20 to 20 percent. Build calculations: New Revenue = SUM([Sales]) * (1 + [Price Change]) and New Profit = New Revenue - SUM([Cost]). Optionally include an elasticity parameter for demand change. Show current versus projected profit side by side, and label assumptions clearly on the dashboard.
27

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.
28

A dashboard with many nested IF calculations on 50 million rows is slow. What would you change?

Calculated FieldsHard
Save to ▾
Show answer
Run a performance recording to confirm calculations are the bottleneck. Replace string comparisons with integer or boolean logic, convert long IF chains on single values to CASE, move derived columns into the database view or an extract so they are materialised, and remove unused calculations. Hide unused fields before extracting. Measure again after each change to show improvement.
29

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.
30

Tell me about a mistake you made in a report and how you handled it.

Table CalculationsMedium
Save to ▾
Show answer
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.
31

How do you calculate the current month and previous month sales in a KPI?

Calculated FieldsMedium
Save to ▾
Show answer
Current Month: IF DATETRUNC('month', [Order Date]) = DATETRUNC('month', TODAY()) THEN [Sales] END Previous Month: IF DATETRUNC('month', [Order Date]) = DATEADD('month', -1, DATETRUNC('month', TODAY())) THEN [Sales] END MoM %: SUM([Current Month]) / SUM([Previous Month]) - 1
32

How do filters interact with LOD expressions?

LOD ExpressionsHard
Save to ▾
Show answer
Extract, data source and context filters apply before FIXED, so they change FIXED results. Normal dimension filters apply after FIXED, so they do not affect it but do affect INCLUDE and EXCLUDE. Measure filters apply later still. Therefore, to make a region filter change a FIXED total, add it to context. Knowing this order prevents incorrect percent-of-total and cohort results.
33

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.
34

Your dashboard has 40 sheets and analysts keep making inconsistent calculations. How would you standardise it?

Tableau FundamentalsHard
Save to ▾
Show answer
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.
35

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.
