Commonly asked data analytics interview questions
Your resume is shortlisted. Now it is time to bring out the big guns and blow away the recruiter at the interview. The best way to do this is to plan for questions that may come up during your first meeting. Such as:
“What are the responsibilities of a data analyst?”
- Analyse data to predict consumer behaviour, spending habits and patterns
- Discover ways to boost productivity and sales
- Help in making sound decisions based on the research findings
- Use the latest software tools to maintain databases for easy access
- Convert the recorded information into insights
- Be aware of the latest trends and emerging technology
“How well do you understand: (insert industry term here)?”
Your recruiter could ask you to define a well-known data terminology. It is important to show you have grasped all basic concepts well.
Let’s say, they ask you about data wrangling:
It is a method where the analyst collects the raw data and cleans it up to appear coherent and structured. It is formatted in a comprehensive way so that the team can gather insights and make sound decisions. Essentially, you are converting a big, complex jumble of data and simplifying it for easy access.
Similarly, they can also ask you about these terms:
- Data mining
- Predictive modelling
- Aggregate and microdata
- 5 Vs of big data
- Business intelligence
So make sure you know your concepts well. If you have done the prestigious PGCM data analytics course, you will be able to define the terms in a clear, coherent manner.
“How would you measure our company’s performance?”
They want to know if you have done your homework about the organisation before the interview. Always do the research.
What are the company’s business goals and targets?
What problems do you think they may encounter?
What is their place in the industry?
How do they fare compared to the competition?
How would you use your skills to add value to the business?
Think it over, plan your strategy and then calmly explain your ideas to your interviewer.
How good are your software skills?
It is a technology-driven job. If you are not adept at using algorithms and software systems, you might as well work in a Macdonald’s. If you have a data science certification, you might already be well versed in the following programmes:
- Microsoft Excel
- Power BI
- Machine learning
You need to efficiently use these tools and techniques to analyse the data and arrive at a well-crafted solution.
“What problems could occur during data analysis?”
It is good to be aware of the challenges that could crop up on the job. Here are some of the issues you could discuss with the employer.
- Duplicate data
- Tampered data quality such as spelling errors
- Collecting accurate data at the right time
- Incomplete data
- Tackling any storage problems
- Securing the data and other compliance issues
You could also discuss data cleansing or wrangling as one of the means to fix some of the problems.
“How would explain data analysis to a layperson?”
Data analysis is a quantitative method where qualified analysts collect, study and classify data to create insights and ideas that can help a company improve their performance and increase profits.
“How would you differentiate data mining from data profiling?”
Data mining is when companies look for hidden patterns in large batches of data. It is then converted into useful information to create business strategies and sales plans.
Data profiling is cleansing and categorising data into structured systems, so they can be ready for further analysis, such as the quality or authenticity of the data.
“How would you confirm if a developed data model works?”
A reliable database model can make predictions for the future. An efficient model can adapt accordingly to changing circumstances and is scalable.
“How would you confirm that the data validation is successful?”
There is a two-step method when we validate data.
Step one, screen the data using multiple algorithms to spot any inaccuracies or fallacies.
Step two, we verify the data by evaluating and examining the information.
