    Growth doesn’t happen by chance. It happens with the right direction.

    Switching from one Big 4 to another wasn’t just about skills, it was about preparation with purpose. Through my professional journey, I faced multiple challenges; however, I was finally able to push myself and make this switch successfully. Here’s the complete story: 

    I had been working as a Consultant in the Data Engineering domain for around 4 years. But while I was in Deloitte although I had gained good experience, I felt it was time to upskill, learn advanced concepts, and move on to a new organization.

    But I knew interviews preparation with my job was possible but I would need help, and so, I started researching different learning platforms, and that’s when I came across Bosscoder Academy.

    It matched exactly what I wanted to learn, focusing on market-relevant skills and consistent problem-solving, which convinced me to enroll in the Data Engineering program.

    Learning & Mentorship Experience

    The instructors at Bosscoder explained concepts in a clear and easy-to-understand way, which made even complex topics manageable. What stood out the most for me personally was the mentorship support.

    I shared a strong bond with my mentor and could reach out whenever I had doubts. He guided me on:

    • How to plan my transition
    • Which companies to target
    • How to approach interviews with confidence

    The doubt support system was also quick and helpful whenever I faced any technical issues.

    Preparation & Results

    With the help of their live sessions, structured learning, and regular revision, my understanding of Data Engineering concepts improved significantly. I became more confident in solving problems and explaining my approach.

    As a result of this preparation, I was able to crack multiple offers from different product companies. In the end, I chose KPMG and switched there as a Consultant in the Data Engineering domain.

    This journey showed me that upskilling with the right structure and mentorship makes a real difference. Bosscoder Academy provided the consistency, guidance, and confidence I needed to take the next step in my career.

    If you’re planning to transition or level up in Data Engineering, I would definitely recommend Bosscoder Academy.
