SQL for Tech and Data Science Interviews (Udemy.com)

This is a good answer. However, in the middle of Mock Interview 6, the interviewer introduced another question about user segmentation by city_ids. The interviewee did not address this question, which seems to have been overlooked.

TL;DR poorly scripted, no response on Q&A, lacks in-depth analysis of each interview to improve understanding of the interview criteria and approach from the interviewee. I wouldn't recommend it but it is one of only a couple of interview courses on SQL. Tina could have done a lot better, but I guess there wasn't enough incentive. They should redo the course. This course really needs a lot of refinement and editing. Results of queries are not shown. Feedback from the interviewer is never provided. Each video pretty much ends with Tina saying that it looks good. What would help is if there was commentary about the interview after to discuss what the interviewer was looking for in the interviewee and whether that objective was accomplished. The interviews are poorly scripted, Tina keeps saying "ok, cool" as a filler for silence. It would be better if she wrote the notes on the screen as to what she was understanding. Often her questions to the interviewer are not relevant to the problem statement, it's as if she's just asking questions to ask something rather than asking poignant questions that clarify what the interviewer is looking for in the query. I asked questions in the Q&A but they were never responded to by the 365 careers or Tina. Lastly, I suspect a lot of the reviews are just her friends. For example Ken Jee is one of the 5-star reviewers and he is one of the people in the course and he works for 365 careers. How many other reviews are just from friends or employees of 365 careers? That skews the overall rating. Smaller content creators don't have that advantage even when they create good content and answer their Q&A. Sorry but unless the course is improved my rating is just 1-star.

Just what I was looking for! The 5 step framework is really useful. The cases are of different variety - range from social media to online ride sharing system. 2.5 hours well spent

Many aspects of SQL interviewing are missed!

I would have loved to hear the feedback side on all of the mock interviews, but questions were quite good to give an overview of what to expect.

i admit, i was too confident in my sql, however that changed after seeing the interview questions that could be asked from different angle, the most important thing i have learnt in this course is CTE, and her sunday sql videos on youtube is icing on cake. I hope she brings out more courses like these,

Great content - Tina is all class and an excellent instructor. It was awesome seeing the thought process behind each of the questions - it helps students immensely!

Tina Huang is very empowering and she knows what she is talking about. Her advice appears very solid and she knows about the difficulties and barriers students are faced often when preparing for job interviews. She is concise, pragmatic and to the point in the videos and it is easy to follow her lectures

Wonderful course so far Tina. I'm I've learned SQL before but I need a refresher. This course is presenting it's self as both a refresher and a challenge. It encourages me to go out an re-learn SQL and excites me for the mock interviews to come.

Amazing content ! Definitely a course worth investing in as it sticks out as a unique course focusing on SQL interviews and doesn't contribute to the abundance of generic courses on the internet !
