Littleflower leveraged structured learning, hands-on training, and certification to restart her career after a gap. Her journey with DataMites led her to secure a role as an Associate Data Engineer, showcasing dedication and practical skill-building.

Q1. Could you introduce yourself and share your academic background?

I completed my MCA in 2020. After graduation, I decided to pursue a Certified Data Science course at DataMites in 2022. Through DataMites, I not only completed my course and internship but also got placed in my first and second jobs via their placement assistance team.

Q2. Were you an online or offline student at DataMites? How was your experience?

I was an online student in the 8:30 PM batch. My experience with DataMites was very positive, with a well-structured seven-month course and a hands-on internship that provided real-world exposure. The placement support helped me throughout the process and assisted me in securing both my first and second job offers.

Q3. Which company did you get placed in, and what is your current role?

I got placed in BDB.AI as an Associate Data Engineer. Before starting officially, I completed a one-month internship, which helped me understand the company’s products and get familiar with practical tasks, preparing me for full responsibilities in my current role. 

Q4.What is the scope of your work in your current role?

It’s mostly related to data pipelines, Python queries, and MongoDB. I’ve just started, so I’m still learning. Even for data engineers or data scientists, having knowledge of these areas is important to develop end-to-end products. I also completed a one-month internship, which helped me get familiar with the company’s products.

Q5. What led you to transition from Data Science to Data Engineering?

Although I trained in data science, the DataMites placement team provided opportunities in related roles too. I appeared for interviews that matched my skills and got selected for a data engineering position because of my Python and SQL knowledge.

Q6. What type of questions were asked during your interview?

Most of the questions focused on Python basics and SQL queries, such as functions, arguments, and basic query concepts like GROUP BY and HAVING. The interviewer mainly tested my foundational understanding.

Q7. How did you build and structure your resume?

Since I had a career gap after 2020, I included:

• My MCA qualification
• DataMites certification
• Projects from my internship
• Experience and skills from my previous job

I made sure to highlight technical skills like Python, SQL, computer vision, and dashboard-building frameworks.

Q8. Did you include project details in your resume?

Yes, I briefly mentioned the projects I completed during my DataMites internship, along with the key tools and technologies used. I kept the project descriptions concise and skill-focused.

Q9. How did you manage your daily schedule while taking online classes?

At that time, I had a career gap, so I dedicated around 4 to 5 hours daily to studying concepts and algorithms. In the evenings, I attended my online classes, cleared doubts, and revised topics immediately after sessions.

Q10. Did you rely only on DataMites training or explore other learning platforms too?

I supplemented my learning with YouTube tutorials and other online learning resources. I believe it’s essential to learn from multiple sources and validate what works best for your understanding.

Q11. How did you overcome the challenge of a long career gap?

Initially, it was tough. I focused on upskilling continuously, taking certifications, and staying updated with the latest trends in data Science and AI. Even though I felt demotivated at times, I reminded myself that consistent effort brings opportunities eventually.

Q12. What role did mock interviews play in your preparation?

Mock interviews during my DataMites internship were very useful. They helped me identify my weak areas and improve confidence. Often, we realize our knowledge gaps only when we try answering questions in real time.

Q13. How many interviews did you attend before getting selected?

I attended four interviews in total. Each interview helped me learn something new about how to communicate and present my technical knowledge better.

Q14. What advice would you give to aspiring data professionals, especially those restarting their careers?

Never give up! Even if you have a career gap or feel outdated, keep learning. The key is continuous upskilling and maintaining a growth mindset. Take guidance from mentors, practice regularly, and stay motivated, your opportunity will come when you’re ready.
