Data Science & AI bootcamp | On campus, full-time Reviews

Wow, where do I even begin? I just wrapped up the nine-week Data Science bootcamp at Le Wagon, and to say it was life-changing feels like an understatement. Coming from a background with very little coding experience, I was pretty nervous, but I can honestly say it was a great decision.The program is an intense, deep dive into the world of data, but it’s structured so perfectly that you never feel lost. We started with the fundamentals of Python and SQL and, before I knew it, we were building and deploying actual machine learning models. The curriculum is incredibly practical and project-based, which was my favourite part. You’re not just memorising theory; you're coding every single day, working on real-world challenges, and applying what you learned immediately.What truly makes Le Wagon special, though, are the people. The teachers are absolute rockstars—many are former students who know exactly what you're going through. They don’t just give you the answers; they guide you to find the solution yourself, creating a supportive and fun learning environment. The final two weeks are spent working in a team on a final project, building a full product from scratch. This was an amazing way to experience agile development and teamwork, just like in a real tech company.The bootcamp is definitely challenging, but it’s also incredibly rewarding. I walked away with a solid foundation in data science, a portfolio of projects I’m proud of, and a huge confidence boost. Plus, you become part of this massive global community of alumni and get lifetime access to the learning platform, which is amazing for continued growth. If you're looking to switch careers and dive into tech, I can't recommend Le Wagon enough. It’s an intense, thrilling, and transformative experience

Amazing bootcamp! I 100% recommend this bootcamp. It made me enjoy learning by myself, gave me all the tools needed to create a successful path in the Data World. The staff is amazing, really nice people, made sure that everyone felt at home. The teachers are all past students so they know what you are going through and are great at helping you out.The campus is really nice and open, everything well functioning and modern. Wouldn't recommend doing any other bootcamp then LeWagon.

# During: Information OverloadA note to the perfectionist voice inside of us:
🤐 SHUT THE F*** UP!!!
📝 This course contains an OVERWHELMING amount of information which my human brain was nowhere near able to digest in one 9-week-go.
♾️ Especially the countless rabbit holes which are sprinkled throughout the course did a great job of evaporating whatever little time I had left myself besides studying in class, studying at home, sleep, socialize, eat, and work-out (ordered by duration).
🌀 For me, being forced to PRIORITIZE and focus on what truly matters to ace the daily challenges and final project with my buddies was an immersive and deeply fulfilling flow-experience. 

# After: Job Seeker Program👔 I signed up for the Comprehensive Job Seeker Program. 
💸 Thanks to my savings, I was not under an immediate financial pressure to find a job during the bootcamp, deferring the job seeker program to the time after the bootcamp, i.e. starting now. 
🤗 I'm grateful that I could embrace this opportunity to become completely absorbed in this coding-learning-bonding experience during the bootcamp while shutting the outside world out as much as possible. 
🪽 Now that the bootcamp is already over (those 9 weeks were FLYING) I am refactoring my first and second brain (physical and digital) to figure out where my journey will continue. 
📈 Although I cannot yet make any statement about the effectiveness of this Job Seeker Program for me personally, it too gives me a very complete first impression, which is consistent with the rest of the bootcamp. 
🎯 Wherever the professional path may lead me from here, my search has become much more targeted and CLEAR to me. 
🫀 Thanks Le Wagon !

I recently graduated Le Wagon's Data Science & AI Bootcamp. The bootcamp is very well structured, covers the most important ML and DL algorithms as well as SQL, Docker, MLflow and cloud platforms such as GCP. It is suited for people without any prior coding experience (like me) but also for people that already have some prior python experience. The teachers are very well prepared and with very strong technical skills. The learning experience is very well supported through Le Wagon's learning platform and the guidance and support of the teachers and the TA's . It finishes with a 2-week team project where one can practically apply the concepts and skills acquired throughout the Bootcamp. Le Wagon also offers top job search services upon successful completion of the Bootcamp as well as  networking platforms for their alumni. The batches are small 10-20 people, which gives you more time for personal coaching and 1 on 1 meetings with the teachers to discuss newly learned concepts or difficulties that have aroused. I am extremely satisfied with my experience throughout the Data Science & AI Bootcamp. It was intensive and challenging, but every bit of it was worth it. I would definitely recommend Le Wagon for anyone that wants to dive into the tech world.

The course provided a fantastic learning experience with practical examples and real life cases. It was quite intense, but that made it a great opportunity to get a broad and comprehensive overview of the different topics. The structure was well organized so it was easy to follow, although at times I would have liked more time to think and breathe, a bigger picture (summary) and the opportunity to speak with industry experts. Overall a valuable and insightful experience.

Our batch was taught by an arrogant instructor who was more interested in showcasing his expertise than helping students get up to speed with the bootcamp content.When this behaviour was called out, I was singled out by the instructor and got into a number of arguments. At one point, I was threatened to be kicked out of the bootcamp.Instead of the situation being managed by the manager, it escalated to the point where the instructor verbally threatened me. To summarise, I didn’t have a positive experience with Le Wagon Bali and will not be recommending it to my colleagues.

My experience at Le Wagon’s Data Science Bootcamp was both challenging and energizing. From day one, I felt immersed in a well-structured curriculum that guided me from the basics of data manipulation to more advanced topics like machine learning and AI. The instructors were genuinely supportive, breaking down complex concepts into understandable pieces, and I really appreciated the sense of community—everyone was learning, struggling, and celebrating together. I left feeling more confident not just in my coding and analytical abilities, but also in my capacity to tackle real-world problems.
