What you may not know is that the importance of learning SQL Interview Questions goes beyond just getting a job!

Believe it or not, getting a SQL job is not as hard as keeping the job after you get it!

In this article I will share the most effective strategies for acing SQL interview questions, getting a job or keeping a SQL job after you get it!

How To Ace SQL Interview Questions

Answering SQL Questions is easy when you realize that almost every SQL job interview is designed to be one of these:

  1. Open Ended Or Essay Type SQL Interview Questions: In this type of interview, you are asked a number of open ended SQL programming questions. However the interviewer is not looking for a textbook or theoretical answer but a practical answer forged from the textbook, real world experience and hands-on knowledge of the question. You score points on each SQL interview question based on how knowledgeable or prepared you sound.

  2. Multiple Choice SQL Interview Questions: In this type of SQL interview, you are made to take a SQL quiz using a testing software program. You may have to answer up to 50 SQL interview questions randomly selected from a question pool. You have to chose the exact answers and your choices are automatically graded at the end of your SQL developer interview.

Acing SQL Interviews Is Easy!

Now, why did I say that both types of interview questions are simple? SQL interview questions are simple because:

  • Limited Question Pool: There is a limited number of interview questions that you could be asked on SQL Queries or Relational Databases (RDBMS) or SQL Joins, Stored Procedures, or their SQL topics! The key is to recognize this in advance and prepare thoroughly and exhaustively.

  • Interview Questions Are 80/20: technical interviews are more practical rather than theoretical in nature. Job applicants tend to be overwhelmed when preparing for interviews because they try to study every possible theoretical questions under the sun! That is so wrong … the truth is that job interviews are designed to test the areas of a skill or technology that you actually use on the job! For example, Normalization to the Third Normal Form is good for most practical database projects. So, staying up late to master all the higher normal forms including Boyce Codd Normal Form is a bit of a theoretical exercise!

The Better Way To Prepare For SQL Job Interviews

The convenient or effective time to start preparing for a SQL Job Interview is not one or two weeks before you a job search! It is better to start preparing months in advance of your job search … that way, when you actually need to take an interview, you will have prepared yourself thoroughly in advance, without any pressure or duress and you have had time to assimilate and understand every nuance of the SQL Programming Language!

Continuous Testing And Assessment

The SQL Boot Camp Online Training Software has an in-built testing program. In addition to the Online SQL Video training you are tested continuously … to check your understanding, retention or application. There are three types of SQL Quiz questions employed by the SQL Boot Camp’s in-built Quiz training system:

  • Single Choice Quiz Questions: In a single choice quiz, you may choose only one answer as the correct answer.

  • Multiple Choice Quiz Questions: In a multiple choice quiz, you may choose one or more answers as the correct answer

  • Essay Type / Open Ended Quiz Questions: In an open ended, essay type quiz, you may provide as much detail as you would in a face to face job interview!

The SQL Boot Camp Online Training Software provides instant feedback to your answers in a single choice or multiple choice question. The feedback includes both the correct answers and the answer explanation.
