Below are some tips that can help you hire an SQL developer to best suit your needs.
What You Should Know About SQL Before Interviewing
Structured Query Language, or SQL, is a database language developed by IBM that is widely used in data management, analytics, and reporting. It can be used to extract information from databases and to create or modify database content.
SQL allows a developer to interact with databases via a user interface. It simplifies the life of a database programmer by automating basic operations such as building databases, tables, extracting data, adjusting data, editing, and deleting unneeded data. In addition, SQL databases are designed to work on different platforms.
Before interviewing a candidate, it might be a good idea to identify the exact reason your organization may need an SQL programmer to be clear and concise in the job posting. It may also be a good idea to get familiar with these platforms to gauge the candidate’s experience. The most common platforms include the following:
- Oracle
- MySQL
- Microsoft SQL Server
- PostgreSQL
- SQLite
- T-SQL
Technical Skills to Look for in a SQL Developer
After you’ve outlined the purpose of your SQL developer, defining the skills you will require from them will be the next step. You may want to hire someone with experience and knowledge related to the project at hand. Also, you will want to look for someone with soft skills such as communication, time management, and self-motivation.
However, technical skills are what will define a potential candidate’s ability to perform the job well. SQL programmers generally have a specific skill set that you may want to look for and we’ve outlined some of the most common ones below:
SQL Technical Background
A general background and knowledge of SQL are essential for SQL developers. In the absence of such knowledge, applicants may try to find information from other sources unrelated to SQL. They also may not be capable of performing with best practices in mind. On the other hand, with a technical background, developers are more likely to have a sense of theory on SQL, which will help them perform their job better.
SQL Version Knowledge
SQL has evolved both in standard form and in vendor-specific needs. For example, later SQL versions have included features like common table expressions and window functions that enable developers to execute complicated reports easier. These characteristics can be very useful in ETL, BI, and reporting. So before hiring a developer, make sure they are proficient in utilizing these capabilities, not just a few fundamental SQL-92 principles.
Database Awareness
Using SQL statements to execute plans requires knowledge of various databases. While the developer’s ability to execute plans is typically enough, understanding databases can help provide the best outcome. A basic understanding of various databases is usually enough; the potential candidate can learn the essential database skills and knowledge on a project to project basis.
Error Identification
The ability to detect mistakes or defects in software is essential to consider when you are in search of an SQL programmer that will bring your project the most success. A well-versed developer will be able to detect errors in their own work. Although indexing may alleviate most SQL performance concerns, knowing how and when to use it is critical to keeping your project on track.
How to Evaluate SQL Skills in the interviews
Once you have narrowed down a list of potential SQL developers with the skills needed for the role, you can start conducting interviews with qualified applicants.
Interviewing potential job prospects offers insight into an applicant’s soft skills, so you can visualize how the candidate will perform with your team. Furthermore, it allows you to confirm that you and the candidate are on the same page regarding the job criteria, which will enable you to better answer any questions they may have.
It’s important to evaluate these applicants based on their SQL competence and hire the best candidate for your project. This can be achieved using some type of technical interview that can assess the candidate’s skills. During this interview, you may want to ask questions like:
- What is the difference between DELETE and TRUNCATE statements?
- What do you mean by table and field in SQL?
- What are the different subsets of SQL?
- What are joins in SQL?
- What are Constraints?
Questions like these allow you to fully gauge the SQL programmer’s skills and make sure they have the necessary knowledge for the job and not just a baseline understanding of the language. If you don’t know much about SQL or need some help putting together a test, there are many free resources available online that provide questions like these and their answers
Keep in mind, answering all technical questions correctly does not imply that someone is the best fit for the job. Instead, utilize each technical interview to plan out a strategy that can help you hire an SQL developer that will be perfect for you and your team.
