Aditya’s Journey into Data Science: A Story of Transformation with DataMites

From an engineering graduate to a skilled data science professional, Aditya’s path highlights how structured learning and perseverance with DataMites led to his career breakthrough.

Q1: Please introduce yourself and share your background.

I completed my Bachelor of Technology in Electronics and Communication Engineering in 2023. During my graduation, I learned Python and had some experience with data structures, so coding wasn’t completely new to me. But I wanted to dive deeper, so I enrolled in the DataMites data science course to learn systematically. I completed the course as well as an internship there, which helped me a lot.

Q2: How was your initial experience with learning Python, statistics, and machine learning?

Since I had already learned Python during my engineering, it wasn’t very tough initially. However, machine learning was challenging because I had forgotten most of the mathematics I had learned earlier — like differentiation and linear algebra. So I had to relearn these concepts to understand machine learning algorithms properly.

At DataMites Institute, I found that we didn’t need deep math — just the necessary concepts to apply machine learning effectively. That was reassuring because many think heavy math is required, but the basics you learn in school and engineering are usually sufficient.

Q3: How important is mathematics for a data scientist?

I used to think math was very important, but after learning through DataMites, I realized you don’t need heavy math for basic data science roles. However, if you want to advance into AI and deep learning, you do need to understand more advanced math like calculus and matrix operations. For most machine learning projects, practical application matters more.

Q4: What about statistics? How was that learning experience?

Statistics was well taught by the instructors, especially Pranu Sir and SS Sir. They covered everything from basic statistics to hypothesis testing and the advanced concepts needed for machine learning. The teaching was very clear, which helped me gain confidence in applying statistical techniques.

Q5: How did your projects and internship help shape your learning?

Initially, I found projects difficult because everything was new. But after completing two projects, I got a better understanding of the process — from data collection and cleaning to model building. Kaggle was an invaluable resource; I learned preprocessing techniques like handling missing values and different coding approaches from many experienced practitioners.

Q6: What challenges did you face in interviews?

I attended three interviews. One was with a company based in Hyderabad where I was asked to write code, but I forgot sorting algorithms during the test and couldn’t clear it.

Another Bangalore-based company interviewed me for about an hour and 20 minutes with basic questions related to my projects and Python coding, like string manipulation. I answered all the questions but never got feedback.

After these setbacks, I realized I needed to improve my coding and problem-solving skills, so I started practicing Python problems on arrays and strings, moving from simple to medium level challenges.

Q7: How did you deal with interview failures?

Failing interviews was tough but I understood that it’s part of the journey. I worked hard on problem-solving, which is crucial for technical rounds. Failures are stepping stones — learning from them and improving is key to eventually landing a job.

Q8: What role did mentorship and structured learning play in your success?

Mentorship was critical. DataMites provided a structured curriculum and great support from instructors. Their clear explanations and real-world examples helped me grasp tough concepts. The classroom environment also allowed me to ask doubts and interact with peers, which accelerated my learning.

Q9: Any advice for beginners looking to break into data science?

Start with Python and basic statistics. Use platforms like Kaggle to practice real projects. Don’t shy away from math but don’t be scared either — learn just what’s needed. Practice coding daily to improve problem-solving skills because interviews test this heavily. Finally, be patient and persistent; it takes time and multiple attempts.

Q10: How did you prepare for your data scientist interview?

I practiced solving Python coding questions extensively from GPT prompts and coding platforms like GeeksforGeeks. This helped me solve two coding questions in just two minutes during the interview.

Q11: How long did it take you to get a job after your training?

I joined the September batch and started preparing for placements by the end of May, with placement team involvement from June. It took about a month or two after training to get job calls.

Q12: When does the placement team usually start contacting students?

The placement team typically contacts students around the sixth month of the course (the course is eight months), during the grooming phase before actual placements start.

Q13: What advice do you have for aspiring data scientists?

Focus on learning from multiple authors and resources. Practice coding consistently. Be hungry for knowledge and persistent in your learning journey because the job will eventually come as a result of your learning.

Q14: Did you apply to jobs independently, like on LinkedIn? Did it work?

Applying independently on LinkedIn often does not work well because many job postings are ghost jobs without responses. It's better to rely on placement teams and focus on skill development.

Q15: What coding platforms do you recommend for practicing data science-related programming questions?

GeeksforGeeks and HackerRank are good platforms for practicing Python coding questions relevant to data science. LeetCode is less important for data science roles.

Q16: Is coding knowledge important for data science interviews?

Yes, coding and problem-solving skills are very important for data science roles because they test your ability to solve problems, not just theoretical knowledge.

Q17: What kind of assignments did you do during your training/internship?

I worked on large datasets requiring preprocessing, clustering into categories, and supervised learning to predict categories, which involved handling complex, similar classes like gaming and entertainment.

Q18: How did you create your resume?

I used a template from a resume website and edited it according to my information. The placement team helped me fine-tune it for every job application to better match job descriptions.

Q19: Which concepts are most important for data science interviews?

Interviewers usually focus on basic machine learning concepts and questions related to your project rather than advanced topics. Programming questions test problem-solving skills.

Q20: How important is data science in today’s world?

Data science is very important because it helps make better decisions by supporting them with factual data and predictions, impacting various areas like business, personal decisions, and technology development.
