Many beginners often ask how to be confident enough to start applying for the job of a Data Analyst. To become a job-ready Data Analyst, you need to practice solving real-world problems that companies expect data analysts to solve 90% of the time. So, in this article, I’ll take you through some common problems you should solve to become a job-ready Data Analyst.
Become a Job-Ready Data Analyst: Solve These Problems
Below are the most common problems that companies expect data analysts to solve 90% of the time. Solving such problems will help you become a job-ready Data Analyst.
Data Cleaning & Preprocessing
Let’s understand why data cleaning & preprocessing is a major problem solved by Data Analysts with an example of the challenges faced by Amazon.
Amazon, handling vast amounts of customer, product, and transaction data, faces data quality challenges like:
- missing shipping addresses
- inconsistent date formats across regions
- duplicate orders due to payment delays
- and extreme price fluctuations from third-party sellers
To ensure accurate insights and smooth operations, Amazon’s analysts use automated ETL pipelines for data processing. They leverage SQL and Pandas for data cleaning, standardization, and preprocessing.

- Project 2: Building a Data Preprocessing Pipeline
Exploratory Data Analysis (EDA) & Business Insights
Let’s understand why Exploratory Data Analysis and Business Insights are major challenges for Data Analysts. We’ll use Salesforce as an example.
Salesforce is a leading SaaS company in customer relationship management (CRM). It faces challenges in reducing customer churn and improving retention. Thousands of businesses use its platform, making churn analysis complex. The business team suspects churn is linked to product adoption rates. Engagement with customer support also plays a role in retention. Pricing models may further influence customer churn.
To validate these factors, data analysts perform Exploratory Data Analysis by examining customer usage patterns, visualizing retention trends, and segmenting accounts based on engagement levels.

- Project 2: Cricket Analytics
KPI & Performance Tracking
Businesses rely on Key Performance Indicators (KPIs) to measure success, track progress, and make strategic decisions. Let’s understand why KPI & Performance Tracking is a major problem that Data Analysts work on with an example of the challenges faced by Amazon.
Amazon is one of the largest e-commerce platforms and continuously optimizes its website layout. It improves the checkout process to maximize conversion rates. Enhancing user experience is a key focus for Amazon’s design team. After a recent homepage and product recommendation redesign, analysts track key performance indicators (KPIs). They monitor bounce rate, click-through rate (CTR), and average session duration. Revenue per user is another important metric for evaluating performance.
Let’s say they discovered that while the new layout has improved product discovery and increased CTR, the checkout drop-off rate has risen due to a new multi-step authentication process causing friction for returning customers. These insights prompt Amazon to refine the checkout flow, to ensure a seamless shopping experience while maintaining security, ultimately leading to higher conversions and customer satisfaction.

- Project 2: Consumer Price Index Analysis
Data-Driven Decision-Making & A/B Testing
Let’s understand why Data-Driven Decision-Making & A/B Testing is a major problem that Data Analysts work on with an example of the challenges faced by Instagram.
Instagram continuously optimizes its platform to improve user engagement and maximize time spent on the app. To encourage more users to create and share Reels, let’s say that Instagram decides to test two different versions of its Reel creation interface. Version A follows the existing design, while Version B introduces a simplified UI with enhanced editing tools and AI-powered suggestions for trending audio and effects.
To determine which version performs better, Data Analysts at Instagram conduct an A/B test by randomly assigning users to each version and tracking completion rates, time spent editing, and the number of Reels published. After gathering sufficient data, analysts will apply hypothesis testing to check for statistical significance between the two versions. This will help Instagram make data-driven decisions using A/B testing.
Here are some resources that will help you master Data-Driven Decision-Making & A/B Testing:
- Course: Marketing Analytics and Measurement
- Project 1: Hypothesis Testing
- Project 2: Building a Data-Driven Mutual Fund Plan
Forecasting & Predictive Analysis
Let’s understand why Forecasting & Predictive Analysis is a major problem that Data Analysts work on with an example of the challenges faced by H&M.
H&M, a global fashion retailer, relies on demand forecasting to optimize inventory and prevent stock shortages or excess inventory. The supply chain team needs to predict monthly demand for different clothing categories, considering seasonal trends, holiday sales, and regional preferences. Data Analyst collects historical sales data, weather patterns, and promotional periods to build a time series forecasting model using ARIMA, Prophet, and regression techniques. Let’s say the model detects patterns, such as increased demand for winter coats in colder months and higher sales of summer dresses before vacations.
By implementing these forecasts, H&M can ensure efficient inventory allocation, reduce overproduction, and improve supply chain efficiency, ultimately enhancing profitability and customer satisfaction.

- Project 2: Stock Market Portfolio Optimization
Customer Segmentation & Behavioral Analysis
Let’s understand why Customer Segmentation & Behavioral Analysis is a major problem that Data Analysts work on with an example of the challenges faced by HDFC Bank.
Let’s say HDFC Bank, one of India’s largest private sector banks, wants to enhance customer engagement by segmenting its customers based on their spending habits and banking behaviour. The bank’s analysts will use RFM (Recency, Frequency, Monetary) analysis to classify customers into segments such as high-value customers, frequent transactors, and inactive users. By analyzing how recently a customer made a transaction, how often they transact, and their total spending amount, the bank identifies that premium customers frequently use credit cards for high-value purchases, while others engage mainly during festival offers.
Using these insights, HDFC Bank can tailor marketing campaigns by offering exclusive rewards for premium customers, cashback incentives for active users, and reactivation offers for dormant accounts.
