Since I work closely with enterprise BI and open-source coding groups, I often interact with them about the kind of interviews and job profiles they are more likely to succeed in. In the countless interactions I had during the COVID-19 lockdowns, I witnessed a significant shift in the hiring pattern of DevOps and Product teams that look out for business analytics professionals. They would rather try out a certified IT professional from a business analytics course than a fresher with no coding or experience in data visualization techniques.
Do you get a hint here?
90% of folks would be awestruck at the word “freshers”, while I would train my senses on the technical aspirations — yes, you got it right the second time. It’s data visualization. Data Visualization skills, for long until COVID-19, I believe, remained a highly territorial skill. Beyond business analysts, or maybe a few handfuls of Marketing and Sales account reps, the rest of the company employees would stay out of the league.
For those who are pursuing a business analytics course, here is a quick guide on the top interview questions that would assist you in your goal — “to grab the job you are interviewing for next.”
What is Visualization Designed for?
This is a very popular question in the interviews. The straightforward answer is not available. Depending on the industry, functions, and departments, the answers could vary. The simplest answer you could provide is:
It depends on the user persona. If it’s for Marketing, the answer is Marketing Forecasts, Customer Analytics, and Marketing performance metrics.
For Sales, the answer could be Sales forecasting or Sales Rep Performance
For Finance, it could be risk assessment, and so on.
Why Data Visualization, and not Testing or A / B Experimentation?
I am in love with the interviews that focus on applications rather than on persona or technicalities.
The best answer I have ever got to this question is: It makes analysts fall in love with data and intelligence. There’s a ton of data available and so many analysts could be working on the same data at the same time. But, the creativity of analysts reflects when tons of data get a visually attractive platform to demonstrate their effect on our decisions, graphically, or in charts. It’s like I am master of my own art — through colours and its effect are entirely created using data–something I would love to do over and over again.” If it helps business decision-makers arrive at a profitable outcome, it’s a great resource for me.
What challenges do Virtualization tools solve?
Data Visualizations solve countless problems that an EXCEL or XML spreadsheet project may not be able to solve. It usually took 3-4 months in the heydays of analytics back in the 90s and early 2000s. But now, thanks to the availability of SaaS-based AI ML Data Analytics tools, the turnaround has been reduced to mere days and in some cases, hours.
So, the simplest answer is – it saves time and resources.
What is the best data visualization format for a business group?
It is basically pointing at the various graphical or visualization techniques you can use to represent data.
The best techniques or formats include:
- Pie Charts / Donuts
- Area Charts / Maps
- Bar Charts
- Bubble plots
Complex problems can be represented in the simplest manner. That’s why a majority of DV specialists look for answers related to heatmaps, plots, and flowcharts.
It’s an era of “graphics and visual content”– so chart your way out, and drive in with infographics. That’s why we are seeing companies like Nielsen Analytics, SAS, HG Insights, GoodData, Sisense, and Oracle focus immensely on the quality of DV and technographics.

The COVID-19 gave EVERYONE an opportunity to try out data visualization, and even improve the overall experience, thanks to Zoom meetings, and employee collaboration, and messaging / planner platforms such as Ring Central, Microsoft Teams, and Google Suite. It’s just astonishing how the data visualization market has entered the mainstream SaaS and B2B Commerce management, with tons of data and analytics coming through.
