I liked the Data Engineering LinkedIn course by Harshit, but I was disappointed by this course, so this wouldn't stop me from checking other courses by him.
My observations:
Writing column names before writing table names is definitely a no-no.
The examples had case-sensitive table names and column names.
There were no relevant examples in the "Outer and cross joins" related to the subject itself.
The examples seemed to lack depth and rushed by.
What I liked was the attempt at different types of SQL challenges, but redoing the course with a better sample data setup and forming the SQL in the expected way, i.e. beginning with the table name and then column names and doing some peer review, would be nice.

Course details
Want to test—and develop—your SQL data-engineering skills? Do you fancy yourself pretty skilled at SQL and want to see just how sharp you are? Then check out this installment of the Code Challenges series, as instructor Harshit Tyagi presents a number of challenges requiring you to write SQL queries to solve problems and answer questions. The challenges start at a relatively low level of difficulty—column selection, filtering rows from data, sorting and grouping query results—and get progressively tougher, testing you on topics like handling missing and invalid data, calculating moving window average, and data transformations. The challenges are all a few minutes long, and use a single database, so you can jump around from challenge to challenge or watch the entire course. So, if you want to see if you’re equal to the tasks, try out these SQL challenges.
