Are you stressed out of losing a big job opportunity? … Or are you afraid of making a bad impression? That’s totally normal before an interview. The best way to overcome interview anxiety is to prepare yourself.

Our SQL Interview Questions course is here to help.

Prepare with 156 popular, real world SQL Interview Questions and walk in confidently knowing exactly what types of questions you will be asked. Impress the interviewer and become the no. 1 candidate on their list.

Why this course?

  • You’ll go over a set of questions that are very likely to be asked on an SQL Interview. The quizzes contain a set of 157 real world interview questions, posted by real candidates and extracted from popular industry sites like: LinkedIn, Stack Overflow, Glassdoor, Reddit and a few other forums. By the end of the course you’ll know exactly what types of questions to expect and how to answer on your interview.  

  • Remember 50% more of the information by taking quizzes. A research lead by Jeffrey D. Karpicke and Janell R. Blunt, published in the Science journal in 2011, found that students who take a test asking them to recall what they know, retained about 50 percent more of the information a week later than students who just read the information. The SQL Interview Questions are structured into 2 quizzes followed by answers so that you’ll remember more during the interview.   

  • Review the information easily before the interview. The answers are written down in text format. You can scroll or search for something that you need easily.
