What is a PostgreSQL test?

The PostgreSQL test is a straightforward multiple-choice assessment that is used as a pre-employment screener.

Candidates complete the PostgreSQL test early in the hiring process via an email link. They are required to answer questions with similar levels of difficulty. To do well in this assessment, they need to demonstrate not only that they have the right level of knowledge about the PostgreSQL system, but also that they are skilled enough to use that knowledge in work-related situations.

Tests like the PostgreSQL test are becoming more commonly used because they are designed to provide easy-to-interpret data for the recruitment team - each candidate has the same opportunity to demonstrate their mastery, so the results can be considered unbiased and quantifiable measurements of skills and ability. This makes filtering through several similarly qualified candidates easier, and ensures only the highest quality candidates are taken further in the hiring process.

About the PostgreSQL Test

In the PostgreSQL test, candidates need to show that they are comfortable working with PostgreSQL as both a primary database and as a backend database, and that they understand what the applications of a geospatial database are.

They need to be able to use different programming languages to create the database and manipulate the data within it.

This test is designed to allow candidates to show their level of skill in using the PostgreSQL environment.

Why should you use a PostgreSQL test?

Although the PostgreSQL environment is all open source, many recruiters will be looking for developers who have a degree in something like computer science or information technology as part of the essential criteria. Even if they state PostgreSQL skills on their resume, actually gauging the level of skill and confidence that a candidate has can be challenging through a paper sift, and it is not easy to do even in an interview situation.

The PostgreSQL test can be inserted into the recruitment process just after the initial paper sift, and this means that if there is a large number of candidates who all meet the basic criteria, recruiters can quickly filter out the applicants who do not have the right level of skill to be successful in the role.

The PostgreSQL test can be administered to a large number of candidates at the same time, and each applicant will complete the test at home. The questions are relevant to the PostgreSQL environment, ensuring that the candidates understand the features of PostgreSQL, how it works in both backend and frontend development, and how it can be adapted to suit different needs.

In the test, candidates will need to show that they understand the importance of high availability and how to achieve this through load balancing, and that they can create a synchronized and useful database system that can be manipulated to produce datasets.

For the candidate, the PostgreSQL test is simple to access and takes very little time, and a suitably skilled and qualified candidate will find the content straightforward.

For the recruitment team, the results are presented in a report that shows how well the candidate will cope in the workplace using these skills. When compared to other test takers, the hiring team will be able to decide whether they are suitable to go further into the process - ensuring that less time is spent ruling out unsuitable candidates and saving time and money.

The PostgreSQL test might be useful for database administrator roles, or any type of database development job.

How our test assesses PostgreSQL skills

In Neuroworx’s PostgreSQL test, candidates will need to answer a range of questions targeting an intermediate level of proficiency, from demonstrating knowledge about the database system to interpreting code to solve common issues.

The test is designed to indicate how well a candidate understands PostgreSQL based on a final test score, which can then be compared to the scores of other applicants.

The multiple-choice questions consist of one correct answer and two to four distractors. The distractors are mostly generic mistakes or misconceptions, which makes the test challenging and helps measure a candidate’s proficiency more accurately.

During the development process, the test was rigorously analyzed to maximize reliability and validity in line with industry best practices. It was created and tested by programmers and psychometric experts, and field-tested with a representative sample of job applicants who have varying PostgreSQL experience, just like you might find in a talent pool.

Each test is reviewed by a panel of individuals representing diverse backgrounds to check for any sensitivity, fairness, face validity and accessibility issues. This ensures each programmer has a fair chance of demonstrating their true level of PostgreSQL proficiency and feels the test is of high quality.

Our programming tests are monitored to ensure they are up-to-date and optimized for performance.

Frequently asked questions

What is PostgreSQL?

PostgreSQL is a relational database system that is designed to be extensible, and it can be used as a primary database, a backend database, or a geospatial database depending on business needs. PostgreSQL supports multiple programming languages and is considered to be one of the most useful database environments currently available.

What is the difference between PostgreSQL and MySQL?

The main difference between PostgreSQL and MySQL is that PostgreSQL has more to it - MySQL is purely a relational database, which makes it simpler and faster, while PostgreSQL is both relational and object-oriented with deeper querying options available.
