After graduation, I explored various industries and discovered the growing demand for data science professionals. My math background made it easier to understand algorithms, and the advice from mentors reinforced that this was the right career path.

Q3. How did you find DataMites?

I researched online and consulted relatives working in IT. They recommended DataMites as a reputable institute for data science training. I visited their center near my home to experience the learning environment and collect materials.

Q4. How challenging was learning Python for you?

Python was initially tough since I did not have a programming background. Learning loops, libraries, and implementing them in real projects took about 2–3 months. Continuous practice helped me become proficient.

Q5. How long did it take you to learn machine learning algorithms?

Machine learning was comparatively easier for me due to my mathematics background. I spent time revising algorithms and understanding the mathematical principles behind them, which helped me implement them confidently in projects.

Q6. What was your learning strategy?

I focused on mastering Python first, then statistics, and finally machine learning. Doing small projects simultaneously helped me apply theoretical knowledge practically. Revising concepts and continuous hands-on practice were key.

Q7. How were your internship experiences?

I completed two internships: first, a data analyst role, where I worked on cleaning data and creating dashboards, and second, a data science internship, where I handled multiple projects, applied machine learning algorithms, and gained practical exposure.

Q8. Did you work in a team for your projects?

Yes, initially, we were five, but ended up as a team of three due to dropouts. Working in a team helped me learn collaboratively and manage real-time project requirements effectively.

Q9. Did you work on live projects?

Yes, I participated in live projects, including performance analysis for managers. This provided real-world experience in implementing data-driven solutions.

Q10. How many job interviews did you attend before landing your first job?

I attended my first interview through DataMites, which perfectly matched my profile. Although I applied to multiple portals, most did not respond. Networking and referrals played a critical role in getting the right opportunity. Fortunately, I was selected in my very first interview at Lenden Club, a fintech company.

Q11. What advice would you give to someone starting their data science career today?

Focus on building strong fundamentals in Python, statistics, and data analysis. Use libraries like NumPy and Pandas, learn visualization techniques, and gradually move to machine learning. Working on projects simultaneously enhances your skills and confidence.

Q12. What were the most difficult concepts for you?

Python programming and certain machine learning algorithms were the most challenging initially. Gaining practical experience through projects made these concepts easier to grasp over time.

Q13. Can beginners from non-technical backgrounds succeed in data science?

Absolutely. Hard work and consistency are more important than background. Even students from non-programming or non-mathematical backgrounds can succeed by dedicating 3–4 hours daily to learning and practice.

Q14: What are the key trends in data science that excite you?

Data science trends such as deep learning, time series forecasting, and large language models continue to evolve. Staying updated and eager to explore new tools is essential, especially for freshers.

Q15. Is a degree mandatory to get a job in data science?

No, a degree is not mandatory. Companies focus more on data science skills and practical knowledge. Candidates without a degree can succeed if they demonstrate strong project experience and proficiency in required tools.

Q16. What resources did you use apart from the DataMites course?

I referred to YouTube tutorials for additional explanations and used ChatGPT as a personal tutor to clarify doubts and learn practical tips. Combining course materials with online resources helped me strengthen my learning.

Q17. What is your advice regarding salary expectations for freshers?

Focus on gaining experience rather than a high package initially. Learning on the job and working on meaningful projects is more valuable than chasing high salaries, which can be achieved later once you gain experience.

Q18. Any final tips for aspiring data scientists?

Be patient, persistent, and dedicated. Build multiple projects, practice regularly, revise concepts, and actively network on platforms like LinkedIn. The combination of skills, practical experience, and perseverance ensures success in this field.
