About the Coding: Data Structures - Hash Tables test

For organizations looking to optimize data storage and access, understanding hash tables is essential. Hash tables are crucial to efficient data management, improving search times in databases, and enhancing caching mechanisms in software applications. This intermediate-level, language-agnostic coding challenge focuses on hash table operations. Candidates have the flexibility to choose their preferred coding language, with configurable options for employers. This test evaluates candidates' knowledge in using hash tables, covering hashing functions, collision resolution, and data retrieval. Candidates tackle moderately complex problems, showcasing their adaptability across various programming languages.

The challenge is evaluated against predetermined cases, and encourages candidates to go above and beyond by creating additional test cases. This gives a comprehensive evaluation of their intermediate programming skills. This screening test serves as a key tool to identify candidates ready for professional growth in coding. Successful candidates will prove their skills in hash table manipulation, and also show the versatility to make significant contributions to complex coding projects.

This language-agnostic Data Structures - Hash Tables coding test ensures candidates are adept at using hash tables effectively, in the programming language they are most comfortable with. Gain insights into candidates' problem-solving capabilities, identify individuals with strong intermediate coding skills, and build a proficient coding team aligned with your organizational needs.

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.
