Or in Haiku-form: 
🌊 Into cold water
🦘 A Wagoneer Leaping up
🍀 Chance of a lifetime
🌸 From 14.04.2025 to 13.06.2025, my body and mind were firmly rooted and blossoming at Carrer de la Diputació, 409, L'Eixample, 08013 Barcelona, Spain. 😄I particularly enjoyed the engaging and challenging learning atmosphere, which was fostered thanks to an amazing group of teachers on-site in Barcelona!  # Before: Comprehensive CurriculumChecking out the curriculum of our bootcamp opens up an in-depth view of all relevant hard- and soft-skills a modern-day data scientist must master:
💻 Setup participant laptops, install software and connect to the KITT learning platform (https://kitt.lewagon.com)

# 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 loved the collaborative environment and the strong support network from both teachers and peers. Practical projects and hands-on coding challenges were incredibly valuable, enabling me to build real-world skills effectively.My experience at Le Wagon has been transformative, significantly boosting my practical skills and professional confidence in tech. It has been challenging yet incredibly rewarding.The London staff was professional, welcoming, and incredibly supportive. Communication was always clear and timely, greatly enhancing the learning experience.

It was an incredible experience and I am so happy to have experience it. I learnt a tremendous amount in a short period of time and made some friends who will remain with me for life. It was a thoroughly rewarding nine weeks and I have memories that will live with me forever. Very grateful to have learnt all that I did. Initially it was very overwhelming but by week 5 it all started to come together. This is me speaking as someone with very limited programming experience.

The bootcamp curriculum content is highly industry relevant, which will be a highly valuable skillsets for our career change. The focus on practical, real-world applications of machine learning, data analysis, and AI ensures that we are equipped with the skills employers are actively seeking. The instructors were incredibly knowledgeable and supportive throughout the bootcamp. Their expertise in both theoretical concepts and practical applications of data science and AI was evident. They were always willing to go the extra mile to answer questions, provide guidance, and offer personalized support, which significantly contributed to my learning experience.

My experience at the Bootcamp was truly transformative. The environment struck the perfect balance between high expectations and genuine support. The instructors were incredibly approachable, demonstrating both deep expertise and a passion for teaching. I especially appreciated the collaborative spirit among the participants: everyone was eager to help each other, creating a tight-knit community where we all thrived.The curriculum itself was dense yet well-structured, blending theory with hands-on projects that brought concepts to life. Working on real-world tasks allowed me to develop practical skills that I can apply directly in a professional setting.What really stood out, though, was the social aspect of the Bootcamp. From informal meetups to fun group activities, there was always a sense of camaraderie that made the intense learning experience enjoyable. I walked away feeling not only prepared for the tech world but also enriched by the strong friendships and connections I formed along the way.In short, if you’re looking for an immersive, practical, and community-driven learning journey, I can’t recommend this Bootcamp highly enough. It’s been an unforgettable milestone in both my personal and professional growth.

It's difficult to decide what my favourite part of the course was, between the wide range of material covered and the atmosphere on campus. I feel like the course really filled in any gaps in my knowledge and exposed me to so many of the major technologies used in industry today. I feel like the atmosphere on campus was very conducive to learning and constructive collaboration and I looked forward to coming in every day.The staff are top notch, always so welcoming and friendly, they led by example and set a wonderful tone. The campus was always clean, well maintained and warm, and the staff were so accommodating with any issues with the classrooms and booking rooms. In summary, the course gave me a new start, was a huge confidence builder, and was worth the large investment! I've already been contacted about two jobs less than a week after the course.

Attending the Le Wagon Data Science Bootcamp was an incredible experience that exceeded all my expectations. The atmosphere was energetic, collaborative, and inspiring, making it the perfect environment to dive deep into data science. The structured curriculum, combined with hands-on projects, allowed me to learn a tremendous amount in a short period.One of the biggest highlights was the community—being surrounded by like-minded individuals made the learning process even more engaging. I made lifelong friends, collaborated on real-world challenges, and felt fully supported throughout the journey. The instructors and TAs were knowledgeable and always ready to help, ensuring that no one was left behind.Beyond just technical skills, the bootcamp was designed to make us job-ready. From working on industry-relevant projects to refining our problem-solving mindset, I left the program feeling confident in my abilities to tackle data science roles.Overall, I would highly recommend Le Wagon to anyone looking to transition into data science or level up their skills. It’s an amazing investment in yourself, and the experience is truly life-changing! 

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.

Honestly, I'd probably give this boot camp four stars. I did hate all the emojis and the words of encouragement saying you're now a "machine learning engineer" or a "Data Scientist", because let's face it, you're not. That's the reason for the one star. In the post 2022 market, completing a bootcamp isn't going to help you  "change your life, break into tech". Just go onto the CS subreddits. You might actually be better off leaving the bootcamp experience off your resume as the market is oversaturated right now. If you're asking for job placement rates, be sure to ask for 2023 or 2024 stats, and in particular the roles people got. The marketing materials often highlight graduates who ended up at say a top company, failing to mention that 1) they were previously employed at a similar company in a different role, and 2) they graduated before 2022. If you have 7k to spend and are just looking for a cool experience, go for it. If you're looking for a job, pick a different industry or do a legit MSCS or MSDS. Gatech's online Masters is about the same price as the bootcamp, but you'll have an actual degree. Nonetheless, even with a Master's finding a job will be an uphill battle. Good luck!

 They make big promises to get you in, but the reality falls short. The person in charge is rude and discouraging, offering little support or guidance. They ask for feedback, but instead of using it to improve, they use it against you, even though it’s supposed to be anonymous. By the end, you’re left feeling stranded. The course has no proper credentials or professional value. Don’t waste your money on this unless you’re fully aware of what you’re signing up for. 

Superbe expérience au Wagon. Pour celles et ceux qui cherchent un bootcamp efficace, je ne peux que conseiller sans réserve le Wagon. Avec toutes les offres qui existent sur le marché c'est compliqué de s'y retrouver !Alors pourquoi ?Comme vous avant, j'ai cherché sur le web une formation sérieuse pour apprendre les bases de Data Science. Une journée type au wagon- Tous les matins nous avons un cours - Exo tout le long de la journée où l'on peut demander de l'aide à un prof (j'insiste sur ce dernier point) - le soir récap avec un live code - petit bonus, en fin de bootcamp, il y a un projet à monter en équipe(ça c'était vraiment cool)Mon expérience perso : Je ne savais même pas ce qu'était Python avant de commencer ! Mon objectif était de monter en compétence grâce à la compréhension technique de l'IA et de la science des données (la partie mathématique). Je viens de 19ans de commerce et de marketing et je voulais apprendre à automatiser mes recherches de data pour gagner en performance. La formation est très intense et assez difficile, je ne le cache pas. Si vous êtes du genre à être humble, à accepter de ne pas comprendre des fois, à demander de l'aide et si vous êtes bosseur alors cette formation est faite pour vous ! A la fin de ce bootcamp, je sais coder, je sais corriger mes problèmes et je sais monter un projet de A et Z en toute confiance et en parfaite autonomie. Je ne cache pas que j'ai eu des moments de doutes mais j'ai continué à travailler et à demander de l'aide quotidiennement au prof. J'insiste sur ce point car c'est vraiment le point fort de ce bootcamp.D'ailleurs les profs sont très compétents, bienveillants et pédagogues. C'est totalement insane. On n'est jamais seul, toujours une personne pour vous aider, vous accompagner à trouver la réponse. Le service administratif est très présent pour vous soutenir tout du long de votre formation. C'était un batch d'été 2024 en petit groupe de 7. J'ai vécu une très très belle expérience. J'espère que ma review permettra à d'autres de se lancer dans l'aventure et à prendre un ticket pour le prochain Wagon.
