Evaluation Metrics: Accuracy, AUC, Confusion Matrix, RMSE


Step 5: Learn Data Visualization & Storytelling

Python (matplotlib, seaborn, plotly)

Power BI / Tableau

Communicating insights clearly is as important as modeling


Step 6: Use Real Datasets & Projects

Work on projects using Kaggle, UCI, or public APIs

Examples:

Customer churn prediction

Sentiment analysis

Fraud detection



Step 7: Understand Cloud & MLOps (2025+ Skills)

Cloud: AWS (S3, EC2, SageMaker), GCP, or Azure

MLOps: Model deployment (Flask, FastAPI), CI/CD for ML, Docker basics


Step 8: Build Portfolio & Resume

Create GitHub repos with well-documented code

Post projects and blogs on Medium or LinkedIn

Prepare a data science-specific resume


Step 9: Apply Smartly

Focus on job roles like: Data Scientist, ML Engineer, Data Analyst โ†’ DS

Use platforms like LinkedIn, Glassdoor, Hirect, AngelList, etc.

Practice data science interviews: case studies, ML concepts, SQL + Python coding


Step 10: Keep Learning & Updating

Follow top newsletters: Data Elixir, Towards Data Science

Read papers (arXiv, Google Scholar) on trending topics: LLMs, AutoML, Explainable AI

Upskill with certifications (Google Data Cert, Coursera, DataCamp, Udemy)

You donโ€™t need to be a LeetCode grandmaster.
But data science interviews still test your problem-solving mindsetโ€”and these 5 types of challenges are the ones that actually matter.

Hereโ€™s what to focus on (with examples) ๐Ÿ‘‡

๐Ÿ”น 1. String Manipulation (Common in Data Cleaning)

โœ… Parse messy columns (e.g., split โ€œName_Age_Cityโ€)
โœ… Regex to extract phone numbers, emails, URLs
โœ… Remove stopwords or HTML tags in text data

Example: Clean up a scraped dataset from LinkedIn bias

๐Ÿ”น 2. GroupBy and Aggregation with Pandas

โœ… Group sales data by product/region
โœ… Calculate avg, sum, count using .groupby()
โœ… Handle missing values smartly

Example: โ€œWhatโ€™s the top-selling product in each region?โ€

๐Ÿ”น 3. SQL Join + Window Functions

โœ… INNER JOIN, LEFT JOIN to merge tables
โœ… ROW_NUMBER(), RANK(), LEAD(), LAG() for trends
โœ… Use CTEs to break complex queries

Example: โ€œGet 2nd highest salary in each departmentโ€

๐Ÿ”น 4. Data Structures: Lists, Dicts, Sets in Python

โœ… Use dictionaries to map, filter, and count
โœ… Remove duplicates with sets
โœ… List comprehensions for clean solutions

Example: โ€œCount frequency of hashtags in tweetsโ€

๐Ÿ”น 5. Basic Algorithms (Not DP or Graphs)

โœ… Sliding window for moving averages
โœ… Two pointers for duplicate detection
โœ… Binary search in sorted arrays

Example: โ€œDetect if a pair of values sum to 100โ€

๐ŸŽฏ Tip: Practice challenges that feel like real-world data work, not textbook CS exams.

Use platforms like:

StrataScratch
Hackerrank (SQL + Python)
Kaggle Code

C - Clustering: A technique used to group similar data points together based on certain characteristics.

D - Data Cleaning: The process of identifying and correcting errors or inconsistencies in a dataset.

E - Exploratory Data Analysis (EDA): The process of analyzing and visualizing data to understand its underlying patterns and relationships.

F - Feature Engineering: The process of creating new features or variables from existing data to improve model performance.

G - Gradient Descent: An optimization algorithm used to minimize the error of a model by adjusting its parameters.

H - Hypothesis Testing: A statistical technique used to test the validity of a hypothesis or claim based on sample data.

I - Imputation: The process of filling in missing values in a dataset using statistical methods.

J - Joint Probability: The probability of two or more events occurring together.

K - K-Means Clustering: A popular clustering algorithm that partitions data into K clusters based on similarity.

L - Linear Regression: A statistical method used to model the relationship between a dependent variable and one or more independent variables.

M - Machine Learning: A subset of artificial intelligence that uses algorithms to learn patterns and make predictions from data.

N - Normal Distribution: A symmetrical bell-shaped distribution that is commonly used in statistical analysis.

O - Outlier Detection: The process of identifying and removing data points that are significantly different from the rest of the dataset.

P - Precision and Recall: Evaluation metrics used to assess the performance of classification models.

Q - Quantitative Analysis: The process of analyzing numerical data to draw conclusions and make decisions.

R - Random Forest: An ensemble learning algorithm that builds multiple decision trees to improve prediction accuracy.

S - Support Vector Machine (SVM): A supervised learning algorithm used for classification and regression tasks.

T - Time Series Analysis: A statistical technique used to analyze and forecast time-dependent data.

U - Unsupervised Learning: A type of machine learning where the model learns patterns and relationships in data without labeled outputs.

V - Validation Set: A subset of data used to evaluate the performance of a model during training.

W - Web Scraping: The process of extracting data from websites for analysis and visualization.
