Question: What do Data Analysts do?

Answer: The first section of Data Analyst interviews might feel a bit like a pop quiz, but even if you’re a relatively experienced Data Analyst, it’s important to be able to answer knowledge questions like this one in a clear and easy-to-understand way. So you could first explain that to validate data – or, in other words, to review the quality of source data – you first perform data screening by using different algorithms to scan a data set for issues. Then, you evaluate any data values you suspect might be inaccurate before deciding whether or not to use them.

Here is an example of a personal interview question a Data Analyst might be asked (and how you can answer it):

Question: Why did you decide to become a Data Analyst?

Answer: Put your storytelling hat on and take the interviewer through your career and how you wound up working in data analytics. It’s a personal question so you will also have a personal answer, but as you discuss your journey, try to weave in specific projects you worked on that confirmed your interest in data analytics (along with the outcomes of those projects).

Other reasons you might be interested in data analytics could include your love of:

• Crunching numbers
• Problem-solving
• Creating compelling and stimulating visualizations to communicate complex ideas

Successful Data Analysts have the necessary leadership and communication skills to make decisions, solve problems, and share insights and findings.

Question: As a Data Analyst, have you ever recommended a change to different tools or techniques? What was the outcome?

With this question, a hiring manager will be looking to see whether you’re the type of difference-maker who can innovate a company’s processes without worrying too much about rocking the boat.

Try to provide a specific example of when you identified an opportunity to improve the way an organization was operating, along with the outcome.

A candidate’s past job experiences can reveal a lot about their skills, knowledge, and abilities. For behavioral interview questions, you will want to provide specific examples of situations, as well as lessons you learned or skills you gained.

Here is an example of a behavioral interview question for a Data Analyst and how you can answer it:

Question: Describe your experience sharing your insights in presentations?

Answer: It’s not just enough for a Data Analyst to be adept at creating brilliant visualizations – they also must have the communication skills and confidence to present that information in front of diverse, sometimes intimidating audiences.

Increasingly, employers will also want to know that you’re comfortable presenting both in-person and virtually. Though it’s hard to quantify success or outcomes in your presentations, you could talk about how much you enjoy getting the chance to go into detail on your work.

Another way to score points with interviewers: mention how you pride yourself on creating presentations that can be understood and appreciated by all audiences, regardless of their technical background. After all, it’s generally much more likely that you will be presenting to audiences of laypeople than other data science or data analytics professionals.
