SQL stands for the Structured Query Language which is used for the purpose of database management as well as manipulation of data. In this day and information, data plays a significant role in the day to day life. Whole structures are built on the foundation of data, and several companies are working in the data services. With the increased reliance on the data for the information, there has been increasing in the demand of SQL developers as well.
However, the scene in the market is such that the supply of SQL developers is more than the actual demand. That makes it problematic for a company to filter through the right contender for the job. Having some sort of test or pre-screening process will make it easier to choose the candidate who meets all the requirements for the job designation.
Overview of SQL
Structured Query Language is utilized for the accessing of databases and also manipulating it if the need arises. In the year 1986, it became a standard for the ANSI- American National Standards Institute. In 1987, it became the standard of ISO- International organization for standardization. It was developed in the 1970s in 1970s and was released by the Oracle in 1979.
The version which is available right now is monitored by ANSI which is voluntary and vendor compliant. Various major companies tend to have their own proprietary versions that are built on the platform of ANSI SQL.
What tasks is the SQL able to perform?
SQL is basically used for the accessing and manipulation of the data, but it has other features as well
- Execution of the queries against the database
- The task of retrieval of data from a database
- Insertion of data
- Updating the records and delete the records as well if the need arises
- Creation of new databases and the creation of new tables in those newly created databases.
- To create stored procedures in a database.
- Creation of views in the database
- The setting of the permissions on procedures, views, and tables
There are different versions of it. SQL is an ANSI/ISO standard, but there are several other variants available, but there is a need to be compliant with the standards of ANSI, so all the other variants support the major commands like SELECT, DELETE, INSERT, UPDATE, WHERE, etc. Quite a few SQL database programs have their own personalized extensions along with the SQL standard.
The enhanced performance is guaranteed when SQL is utilized because it ensures that the performance of the database is guaranteed. The processing method also gets efficient and quicker. SQL provides the extra choices as well for the modification purpose of the operation.
Versatility is a beneficial feature as well because it lets you run the database within an operating method. It is a cost-effective method too because in comparison to the other variants and is quite user-friendly as well.
Why is there a need for an assessment procedure before hiring a candidate?
The developer market is scaling at a high rate, and even then it is not enough to meet the supply. That is because the number of people getting educated and getting degrees and certifications about the developer roles is extremely high in number.
That leads to the clash of the whole concept of supply and demand. The establishment of the firms, start-ups, and companies are for the sole purpose of scaling and garnering profits. The interview process to becomes tough if there are only a few positions to fill and in turn of it, the applications are way too more. That gets hectic for the employers as well, so there has to be a certain amount of process which can make the task of hiring easier. Luckily, now there are such systems in place.
They are known as the assessment tests which are used as a screening procedure for the hiring process. It enables the company to set the test as per their requirement and because of that, if the candidate gets successful results, then only he or she can get hired.
SQL Developer Tests
The basic point of such tests is to provide the SQL challenges to the candidates, and if they get a good score on it, then only the next process can be done. The role of a SQL developer is to write the functions, programs, and the queries as well so that he or she can manipulate the structure and data of a database by utilizing the Structured Query language.
In some cases, there might be a requirement to write the custom queries for the generation of reports. This test can be used for the job profiles of SQL developer, Software developer, and Database developer. For several other profiles, this test can be used. The test is used as a pre-screening task and checks whether the candidate is proficient in the works of SQL, its basics, knowledge of key concepts, analytical skills and the hands-on test of the skill implementation.
The way these tests work is that the company will create the test and questions will be in such a way that it meets the requirements of the designation. Then this test would be shared with the candidate who is there for the job. Upon completion of the test, the performance can be easily reviewed by the company, and if it is up to the mark, then the further discussions can be done. A lot of companies are now implementing this method for the hiring process.
There are several platforms and portals which also offer the service of the creation of customized tests to suit the requirement of the company. If a company wants to hire a suitable candidate for a particular job role, then having such test criteria as a part of the hiring process will make it easier to filter the prospects. It is vital to hire a candidate who would prove out to be helpful for the scaling of the company and ensure personal growth as well.Sponsored Post
