Thanks to Kyle, I passed the SQL Test and job interview at a domestic unicorn company! Even though I'm an experienced worker, it was my first time taking a coding test, so I was actually quite nervous, but I solved it so easily. The retention problem that you said "comes out when you put in the effort" really came out😆😆 I solved it the easiest thanks to the logic that we covered a lot in the lecture! To be honest, I don't think that "just listening will guarantee you to pass". I participated in a study group, worked hard on solving problems, analyzed other people's solutions in the lecture community, and made my own problems using the data sets you provided and solved them... I tried my best to do as much as I learned. <Tips for getting the most out of the lecture> Beginner: Just listen to the lecture Intermediate: Solve the homework yourself and practice Advanced: Use the community and don't hesitate to get 1:1 coaching (+ I got a lot of advice 1:1 and passed the job interview🤙) Also, many people don't know about the Inflearn roadmap feature, so check it out. https://www.inflearn.com/roadmaps/4639 I've received a lot of help from your blog a few years ago to this lecture, but this is my first time leaving a review. Thank you for being my mentor outside of my company, from my first job search to my work and when I changed jobs🙏 I'm looking forward to the next lecture that you announced at the end!!!
