  • Young Tse (4/5) : However, it has still helped a great deal as there are lots of similarities in both.
  • Travis Johnson (5/5) : Great course to give you insight on what to expect on database interviews.
  • Aakash Behl (5/5) : best course i ever purchased on udemy, many of these questions were asked in my job interview 1 weeks ago, i wish i had done this course a week ago


  • Sharon Morris (1/5) : It is not very interactive and it is difficult to understand the instructor at times
  • Akram Mirza (1/5) : chapter 13 with clause example is too difficult to understand and no material provided for further review.
  • Chris H (2/5) : Much of it is only for Oracle, some of it is just wrong for non-Oracle databases and whole sections are just irrelevant for non-Oracle.
  • Sonali S (2/5) : Examples are not shown in SQL developer for each and every interview question which makes it difficult to understand.
