An amazing experience into the fascinating world of data
This bootcamp is a great opportunity for everyone interested to meet the latest trends and tools in the field of data science.
Specifically, it is designed to provide expertise not only in the theoretical concepts, but also in hard skills that are necessary prerequisites to every data science job description. As a student I found the entire course to be beneficial in building my knowledge over python, visualization tools, machine learning, neural networks etc. Furthermore, every weekly project and the final big project(with a partner company) added valuable experience to my journey. All instructors in Big Blue are acclaimed in their domain, with a prestigious career in EU companies and they provided all the support and guidance we needed. Last but not least, I was happy to have 2 job offers, even before the ending of the bootcamp and at the moment I work as a mid-senior Data Analyst!Overall5.0Curriculum5.0Job support5.0Instructors5.0 -

Valuable knowledge
The bootcamp was everything I could ask for. Experienced instructors and everyone is always available to help. But the most important part that made this bootcamp stand out is the everyday and weekly application of everything we had already learned, plus the final project, that we worked for a company's project. Also, the classes about the soft skills were especially helpful.Overall5.0Curriculum5.0Job support5.0Instructors5.0 -

An excellent Business Intelligence (BI) Bootcamp
This BI Bootcamp is a great investment for anybody who wants to gain some new or expand already existing knowledge in the of Business Intelligence and Data Analytics.
The Bootcamp is very intense with a lot of exercises, so be prepared to spend some extra hours if you want to succeed.
Positives
* High organization
* Complete curriculum with extended knowledge
* Many exercises and 2 projects (mini & final) for hands-on training
* Very good, helpful and willing to help instructors
* Cooperation is encouraged in general
* CV writing, interview preparation, LinkedIn creation or optimization
* Job assistance
* Live-online with the opportunity to learn from the comfort of your own place. Money & time savings.
Suggestions
* The program is pretty intense with many exercises which makes it difficult to complete at least most of them. In my cohort (2-6/2026), most of the students didn't completed a lot of the exercises. This fact created some gaps at the learning process. Maybe more hours should be spent for this progam
Overall it was a great Bootcamp and experience!
Couldn't rate with less than 5 stars! Great Job! Thank you!Overall5.0Curriculum5.0Job support4.0Instructors5.0 -

Practical and Well Structured
I recently completed the Business Intelligence Bootcamp at Big Blue Data Academy, and overall it was a very positive experience.One of the strongest aspects of the program was its structure. The curriculum was well organized, progressing from fundamental concepts to more advanced topics in a logical way. Rather than focusing only on theory, the bootcamp emphasized practical application through hands-on exercises, business cases and projects using industry-standard tools such as Excel, SQL, Power BI, Tableau and KNIME.Another major strength was the support provided by the instructors. They were approachable, knowledgeable and always willing to answer questions, clarify concepts and provide guidance whenever needed. This made the learning process much smoother, especially when working on more challenging assignments.The final team project was an excellent way to consolidate everything we had learned. Working with a real-world dataset, building a complete BI solution and presenting our findings helped bridge the gap between learning concepts and applying them in practice.There is, however, one area that could be improved. In some of the badge certification exams, a few questions covered topics that had not been addressed during the course, while others were phrased in a way that made the correct answer open to interpretation. Improving the alignment between the course material and the assessments, as well as making some questions more precise, would make the certification process even stronger.Overall, I would definitely recommend this bootcamp to anyone looking to build practical Business Intelligence and Data Analytics skills. It provides a solid foundation, extensive hands-on experience and excellent instructor support, making it a valuable choice for both beginners and professionals looking to transition into the field.Overall5.0Curriculum5.0Job support5.0Instructors5.0 -

A Challenging but Valuable Bootcamp
Overall, this was a demanding but very practical bootcamp focused on Data Analysis and Data Science. I started with almost no programming background, so the learning curve was definitely steep for me. Still, the structure of the program, the live coding sessions, and the daily exercises helped me build my skills gradually and understand how to approach problems in a more practical way.What I appreciated the most was the hands-on part of the bootcamp. The live coding sessions, the weekend projects, and especially the final one-month project gave me a much better sense of how to work under pressure, collaborate with a team, ask the right questions, and move towards a common goal. The instructors were patient and knowledgeable, and they clearly had real experience from the job market. Many times, when we asked questions, they answered with examples from their own professional experience, which made the lessons much more useful.The bootcamp was not easy, and I think you need to invest serious time and effort to get the most out of it. But if you do, it gives a lot back. By the end, I had completed several projects, built a stronger technical foundation, and created a portfolio that can support my next steps in the Data field.The main thing I would improve is the pacing of the curriculum. Some earlier topics received more time than necessary, while some of the harder topics near the end felt a bit rushed. I also think the theory and live coding parts could be more connected, with small practical examples during each topic presentation, so the transition to coding feels smoother.I would recommend this bootcamp to people who already work in Data Analysis and want to move further into Data Science, but also to career changers who are ready to put in the work. For someone looking for a practical alternative to a more traditional academic path, the projects and hands-on experience are a major advantage.Overall5.0Curriculum4.0Job support5.0Instructors5.0 -

I recently attended the Professional Diploma in Data Analytics at Big Blue Data Academy, and I must say it was an exceptional experience. The course content was not only highly relevant and insightful but also presented in a very engaging and practical manner. The instructors were incredibly knowledgeable, approachable, and genuinely passionate about the subject, which made learning both enjoyable and inspiring.
What I particularly appreciated was the perfect balance between theory and hands-on practice, allowing us to immediately apply the concepts in real-world scenarios. In fact, I have already started using what I learned in my current work, which has made a tangible difference in my daily tasks. The overall structure of the program was well thought out, keeping the sessions interactive and stimulating.
I wholeheartedly recommend this program to anyone looking to deepen their understanding of data analytics and gain valuable, actionable skills. It was an inspiring journey that truly exceeded my expectations!
