It was a huge help because you provided a bird's-eye view of the flow of follow-up questions and the interviewer's intentions, which are things I hadn't been able to consider deeply as a job seeker! In particular, by clearly comparing and analyzing answers for the same technical question across different levels—from Bronze to Gold—I was able to specifically correct the issue of not being able to articulate things properly in an interview despite knowing them in my head. It even allowed me to conduct my own mock interviews. I felt that DB was my weakest area, so thank you for the great lecture!! I'll work hard and get that job! 🎉
