5 DATA ANALYSIS QUESTIONS YOU MUST KNOW HOW TO ANSWER

5 Questions for Data Analyst Interviews

5 Questions for Data Analyst Interviews

After working as a Data Analyst for almost 6 years, I have both experienced and observed multiple interviews. I'm here to share 5 questions that you can practice to increase your chances of success during this stage.

Why is this Important to You❓

I want to share my experience to save you the stress of preparing for interviews.

How can You address this❓

Let me give you a real-life example that you can use to prepare for any data-related job application. This exercise will help you develop critical thinking, communication, and thought processes.
Just imagine the recruiter asking you the following questions ⬇️

  1. 'We don’t know where this data is. How would you try to find the data?'

  2. 'What would you then do?'

  3. 'What kind of insights would you want to look for?'

  4. 'What if the data is missing?'

  5. 'What if the data has poor quality?'

By developing the what ifs” and “then what’s” mindset, you can build the problem-solving skills that most companies seek (even more than advanced technical knowledge).

DATA SKILLS TIPS
A DATA ANALYST BLUEPRINT TO IMPROVE VISUALIZATIONS

Not Applying Visual Hierarchy

Applying Visual Hierarchy

I've built dozens of dashboards, and let me tell you, to create great visualizations, you must practice. However, practicing without guidance won't necessarily make you better—it will just make you comfortable. So, I’m offering you 8 tips that you can use today to upgrade your visualization toolkit.

Why is this Important to You❓

The difference between a good visualization and a bad one lies in the small details. I’ll be sharing those with you in this article.

How can You address this❓

Here are some 8 tips to improve your visualizations⬇️

  1. Apply Visual Hierarchy: People have different levels of attention span. Using colors to provide contrast helps your audience quickly identify the most important information, making your message more engaging without using too much of their brain power.

  2. Avoid non-relevant comparisons: Avoiding invalid comparisons due to different timeframes or units will help you keep credibility. If you don’t have historical data to use, compare it with industry benchmarks or competitors.

  3. Make it measurable to make it understandable: Stating that Elon Musk’s fortune is valued at 206 billion dollars might not be impactful. However, explaining that if you distributed that money among every U.S. citizen (approximately 332 million), each would receive about $620 might offer an impactful perspective.

  4. Keep it simple: Most of the time, line charts and bar charts are all you need.

  5. Pay attention to typography: To highlight a key statistic in a presentation, use a larger font size and bold text.

  6. Use the right type of animation: If you have multiple focal points, introduce them sequentially using animations. This will guide the audience's focus.

  7. Base your story on data: If you’re making presentations on historical trends, start with a line chart to show past performance and end it with a dashed line to forecast future trends.

  8. Use cheat sheets: When you need to communicate quickly with small audiences, give them printed data visualization cheat sheets. These will help your audience to reference key information, thus decreasing the need for extensive explanations.

A day in My life

A day in My life

Being a Data Analyst and Content Creator is challenging, but I've consistently managed it for over a year. Now, I want to share 4 rules that I personally use to keep it healthy and sustainable.

Why is this Important to You❓

If you’re after a sustainable approach on living a healthy life, you'll like these four 4 rules that I cannot live without.

How can You address this❓

These are my baseline conditions for my everyday life ⬇️

  1. Working Out: Schedule your workouts; mine are non-negotiable at 7:00 AM, right after coffee. Taking care of your body is the first step to mental health.

  2. Prioritization: My schedule includes days filled with meetings. I take 10 to 15 minutes after each one to outline important tasks and set priorities for the rest of the day.

  3. Lunch Walk: I never skip my midday walks with my wife and dog, which boosts my energy levels for the afternoon.

  4. Shutdown Routine: At the end of each day, I summarize key action points to avoid confusion the next morning.

Current Schedule:

  • 07:00 AM: Workout

  • 09:00 AM: Work

  • Noon: Check emails and handle documentation, plus family time

  • 02:00 PM: Resume work

  • 06:00 PM: End workday, followed by family time

  • 09:00 PM: Work as a Content Creator
