5 Tableau interview questions with sample answers
These are some common interview questions for job candidates who specialise in Tableau, along with the reasoning behind them and a sample answer for each:
1. What is your experience with Tableau?
Some hiring managers choose to start their interview by asking you to describe your proficiency level with the software. When answering this, it's important to use concrete examples of your past work to demonstrate your experience using Tableau for various purposes. When describing the projects that you completed using Tableau, you can also discuss the skills you developed during the process.
Example answer: 'I have about a year of experience using Tableau for data compiling and organisational purposes. I mostly used it to visualise and query data by using SQL language programming and to transfer information between internal and external sources. After gaining some knowledge and experience in Tableau, I earned my Tableau data analyst certification and I plan on continuing to expand my related knowledge.'
2. Can you tell us about the different filters in Tableau?
Tableau filters help users select specific data from a large database. Interviewers may ask about filters to assess your proficiency in quickly and accurately sorting large amounts of data. You can answer this question by mentioning the three types of available filters, along with a brief description of each.
Example answer: 'There are three types of filters in Tableau. They each help you restrict different types of data from a given database. The normal filter selects data from the entire database based on a single criterion. The quick filter can filter each worksheet on a dashboard in real time by changing values dynamically. The context filter helps you filter the data from each worksheet by creating a temporary flat table to help it compute the chart.'
3. Can you mention all the different Tableau products?
Tableau has five different sub-products with slightly different characteristics. The recruiter may want to assess your experience using Tableau in different scenarios by asking you to discuss each of them. You can answer by mentioning all of them, along with a brief description of each.
Example answer: 'There are five Tableau products. Tableau Desktop is an easy-to-use desktop solution for business analytics and data visualisation. Tableau Server is its enterprise version that's for larger organisations. Tableau Online is a cloud-based version that helps users perform analytics and visualisations on the go. Tableau Reader is a free app that allows users to view existing Tableau Desktop dashboards. Tableau Public is also free. It helps users make visualisations and allows them to save their workbooks in a public file.'
4. Can you discuss a project you completed using Tableau's public version?
The interviewer may want to gain deeper insight into your proficiency in using Tableau's different versions and ask you about a specific situation in which you used one of them. If they ask about Tableau Public, they usually want to assess both your Tableau experience and your ability to distinguish publicly available data from confidential information. You can answer by mentioning a specific situation in which you used Tableau Public to share your work with other parties, such as customers, shareholders or the general public.
Example answer: 'I used Tableau Public to help my organisation's business clients share the information I provided to them with key stakeholders. Before introducing the data into the public version, I first made sure to eliminate potentially confidential information, such as earnings numbers, investment plans and product milestones. To keep this information separate from the public dashboard, I had to create distinct data queries and files within the public domain.'
5. How do you assess and use different data sources?
The ability to use Tableau to combine multiple related data sources and extract relevant information from them can be a valuable skill sought after by hiring managers. When answering, you can provide examples of how you used multiple data sources in the past. If relevant, you can also mention your ability to identify and evaluate data sets from both internal and external data sources.
Example answer: 'When I'm working on a system with multiple data files, I check many factors to identify the different types of sources. Their file names usually provide me with important information, including each file's source, location and most recent extraction. In some instances, I also analyse the connection type and its location.'
Interview tips for candidates for Tableau-related roles
Consider following these tips when interviewing for a role that requires Tableau proficiency:
Make sure you emphasise your soft skills: While any tech-related job requires a distinct set of specific skills, you can gain an advantage over other job candidates by also showcasing your soft skills. You can use the interview to demonstrate your communication skills, attention to detail and critical thinking ability.
Practise answers for common interview questions: Some questions, like the ones regarding your background, skills and desire for the respective role, are likely to come up in any job interview in different forms. You can make sure you give an appropriate answer by reading the job description, researching the company to make sure you understand the requirements for this role and formulating some sample answers and rehearsing them before the interview.
Prepare relevant questions: Although the recruiter usually asks most of the questions during an interview, you can show your interest and competence by asking your own questions during the conversation. It's usually best to compose them before the interview and then ask them at an appropriate time.
