About the Database Development test

In the current age of information and technology, every business deals with complex software and web applications, each of which requires data storage via a database management system. It is crucial to have professionals on staff with fundamental knowledge of database development and its best practices to be able to efficiently store and access the information you require.

Hiring a developer with strong database development skills means that you will reduce the amount of time you spend managing data, improve the quality and consistency of the information you use to guide your business decisions, and turn disparate information into a valuable resource for your company.

The correct development and implementation of a database management system (DBMS) provides an opportunity to develop complex applications that work efficiently and can deal with the load from millions of user requests. It also provides the ability to easily store and access any piece of information.

The questions in this test are related to all core concepts of relational DBMS and database development, covering data models, optimal database design and normalization, transactions, and indexing.

Candidates who perform well on this test have a strong fundamental knowledge of core DBMS and relational database development approaches and can make the best use of each one when working with different types of information. In addition, such candidates have all the necessary skills to help your company achieve its goals in the storage, management, and accessing of data.

VP of engineering, mid-market (51-1000 FTE)

Any tool can have functions—bells and whistles. Not every tool comes armed with staff passionate about making the user experience positive.

The TestGorilla team only offers useful insights to user challenges, they engage in conversation.

For instance, I recently asked a question about a Python test I intended to implement. Instead of receiving “oh, that test would work perfectly for your solution,” or, “at this time we’re thinking about implementing a solution that may or may not…” I received a direct and straightforward answer with additional thoughts to help shape the solution.

I hope that TestGorilla realizes the value proposition in their work is not only the platform but the type of support that’s provided.

For a bit of context—I am a diversity recruiter trying to create a platform that removes bias from the hiring process and encourages the discovery of new and unseen talent.

FAQs

An assessment is the total package of tests and custom questions that you put together to evaluate your candidates. Each individual test within an assessment is designed to test something specific, such as a job skill or language. An assessment can consist of up to 5 tests and 20 custom questions. You can have candidates respond to your custom questions in several ways, such as with a personalized video.

A video question is a specific type of custom question you can add to your assessment. Video questions let you create a question and have your candidates use their webcam to record a video response. This is an excellent way to see how a candidate would conduct themselves in a live interview, and is especially useful for sales and hospitality roles. Some good examples of things to ask for video questions would be "Why do you want to work for our company?" or "Try to sell me an item you have on your desk right now."

Besides video questions, you can also add the following types of custom questions: multiple-choice, coding, file upload, and essay. Multiple-choice lets your candidates choose from a list of answers that you provide, coding lets you create a coding problem for them to solve, file upload allows your candidates to upload a file that you request (such as a resume or portfolio), and essay allows an open-ended text response to your question. You can learn more about different custom question types here.
