The company explicitly asked for 5 star reviews to be written in exchange for extended access to its learning content. This is a direct violation of Trustpilot's rules. When this was pointed out, Zach Wilson did take away the incentive. Trustpilot is very clear that businesses should not be offering incentives. It's disappointing that it took a few honest reviews in the sea of hundreds for this company to change its practice. It's made me distrustful, on top of my disappointing experience with the content. I took the free beginner data engineer bootcamp. It has been disorganized since the beginning. The biggest disappointment was the lack of homework. Zach spent a significant portion of the pre-bootcamp video emphasizing the importance of doing the homework assignments to the learning process, including a demo of how to submit the homework for feedback. However, there have been no assignments. If this bootcamp was just meant to be a series of videos, it should have been advertised as such. The pre-bootcamp video is longer than the entire bootcamp combined. It's unclear if there is more content coming. Yesterday's incentive email says there is, but a moderator on Discord says all of the content for the beginner bootcamp has been posted. Based on this experience, I have no interest in pursuing any of the paid materials. While Zach has a lot of experience, an expert's stream of consciousness doesn't automatically translate to helpful learning.

Thank you for your feedback — I understand your concern. To make sure everything is fair for all students, we’ve extended access for everyone from November 24th to December 28th, with no review required. Reviews are completely optional and never a condition for continued access. I appreciate you bringing this to my attention. The absolute beginner boot camp will continue over time (give it 3-4 more months). Truly apologize for the delays in the roll out of that.

Zachary is adding so much value to the data engineering field by helping the community understand complex concepts by using very direct and easy to understand lectures. Thanks a lot for the knowledge shared within your platform

The Community Bootcamp is a blast! However, you will have to research further to be able to understand the concepts better. It is best suited for those who already have background knowledge about data engineering. Overall, it's great because you'll learn a lot and it's for free! :)

I am deeply grateful. As a soon-to-graduate student, I feel fortunate to have had the opportunity to join this community, learn from everyone, and share knowledge along the way
