Shubham’s Transition from Hardware Automation to Data Science

Read how Shubham successfully moved from hardware automation into data science through structured learning, continuous upskilling, practical projects, and real-world industry exposure at DataMites.

Q1. Please introduce yourself.

My name is Shubham, and I completed my engineering in Electrical Engineering. I initially worked in the hardware automation field after graduating in 2019. During that time, I became interested in the growing opportunities in data science and machine learning.

Q2. How did your journey into data science begin?

While working in automation, I learned about the growing impact of AI and machine learning from colleagues and friends. During the COVID-19 lockdown, I joined DataMites to build my knowledge in data science and machine learning. At that time, technologies like GPT and large language models were still emerging, and I wanted to prepare myself for future opportunities in this field.

Q3. Did you have any prior IT or programming background?

No, I did not come from an IT background. Since I was from Electrical Engineering, most of my experience was related to hardware and automation systems. However, I had basic exposure to programming concepts during engineering, which helped me understand coding fundamentals.

Q4. Was learning Python difficult for you?

No, Python was comparatively easier to learn because of its simple syntax. Understanding programming logic during engineering also helped me adapt quickly to Python programming.

Q5. What was the most challenging part while learning data science?

The challenging part was understanding statistics, machine learning concepts, neural networks, NLP, and the mathematical foundations behind machine learning systems. Since these technologies were still evolving rapidly at that time, understanding how models worked internally required continuous effort and learning.

Q6. How did DataMites help in your learning journey?

DataMites helped me build a strong foundation in machine learning, modeling, mathematics, and statistics. The trainers provided preparation notes, practice materials, assessments, and guidance that helped me understand concepts clearly and stay consistent throughout the learning process.

Q7. Did you use additional learning resources apart from classroom sessions?

Yes, apart from training sessions and notes, I regularly referred to YouTube videos, online tutorials, and free Udemy courses to strengthen my understanding. I believe continuous learning and staying connected with new technologies is very important in data science because the field evolves rapidly.

Q8. How important are fundamentals in data science?

Fundamentals are extremely important. Before learning advanced concepts, it is necessary to understand the basics of machine learning, statistics, and modeling clearly. Strong fundamentals make it easier to learn advanced technologies later.

Q9. Did you work on projects during your training?

Yes, I completed multiple capstone projects during my training. These projects helped me apply theoretical learning to practical problems. I also worked on time-bound assignments and certification-based projects that improved my understanding of real-world implementations.

Q10. How did projects help you during interviews?

Projects played a major role during interviews because interviewers focused heavily on practical implementation rather than only theoretical knowledge. The projects also helped me build GitHub repositories where I showcased my work and technical skills.

Q11. How did you prepare for job interviews?

I spent a lot of time understanding company requirements and industry expectations. I attended multiple interviews during the initial phase, and every interview helped me understand what companies were looking for in data science professionals.

Q12. Did you face rejections before getting selected?

Yes, I faced multiple rejections initially. However, every interview gave me new insights and helped me improve my technical knowledge, confidence, and interview preparation.

Q13. What was your strategy while starting your career in data science?

My focus was not initially on salary. I wanted to gain practical industry exposure and real-world project experience. Once I started working on real projects, learning and career growth became much faster.

Q14. What advice would you give freshers for getting interview calls?

Freshers should build strong resumes aligned with job descriptions. It is important to include projects from multiple domains like prediction systems, NLP, sentiment analysis, and pipelines. Resume keywords, ATS optimization, and showcasing practical skills are very important today.

Q15. Which interview platforms and resources are useful for freshers?

Platforms like LinkedIn and Naukri are very useful for job applications. Freshers should also regularly monitor job descriptions to understand current industry requirements and skill expectations.

Q16. What technical skills are commonly asked in data science interviews?

Interviewers usually focus on machine learning basics, statistics, data preprocessing, algorithms, hyperparameter tuning, sampling methods, and scenario-based problem-solving questions. Basic Python programming questions are also frequently asked.

Q17. Are programming rounds difficult for freshers?

No, most programming rounds for freshers focus on basic Python concepts, loops, libraries, and logical thinking. The main objective is to evaluate whether candidates understand programming fundamentals.

Q18. What skills should freshers focus on initially?

Freshers should avoid overloading themselves with too many technologies at once. Instead, they should focus on understanding one domain clearly, whether it is machine learning, NLP, pipelines, or predictive analytics systems. Strong clarity in basics and projects is more important than superficial knowledge across multiple areas.

Q19. Is Deep Learning important for freshers?

Yes, understanding deep learning architectures, neural networks, RNNs, and model structures is beneficial. Interviewers often ask conceptual and architecture-related questions to evaluate understanding rather than memorized answers.

Q20. What is your current role at Accenture?

Currently, I work as a Senior Data Scientist at Accenture. I work on predictive analytics projects, fraud prediction systems, agentic API development, and machine learning solutions for business use cases.

Q21. What does your day-to-day work involve?

My daily work includes understanding business requirements, discussing use cases with stakeholders, data preprocessing, building machine learning models, pipeline development, and ensuring project delivery within deadlines. Understanding the business problem is often more important than simply writing code.

Q22. Which tools and technologies do you currently use?

I work with Python, Databricks, VS Code, Azure pipelines, CI/CD systems, and machine learning workflows. Depending on project requirements, we also use internal enterprise tools and systems.

Q23. What is your biggest advice for aspiring data science professionals?

Focus on mastering the basics first. Understanding machine learning concepts, business requirements, and problem-solving approaches is more important than memorizing complex coding techniques. Stay curious, keep learning, and continuously improve through projects and practical implementation.
