About the Coding: Data Structures – Binary Trees test

For organizations seeking skilled coders, a strong foundation in binary trees is crucial. Binary trees play a key role in the efficient navigation and manipulation of hierarchical data structures, which is crucial in tasks such as database management, file systems, and data processing. This intermediate-level, language-agnostic coding challenge concentrates on binary tree manipulation. Candidates have the flexibility to choose their preferred coding language, with configurable options for employers. This test rigorously evaluates candidates' ability in manipulating binary trees, an essential skill for effective data organization and retrieval in various computing scenarios. Candidates engage with moderately complex problems, displaying their versatility across different programming languages. The challenge is assessed against predetermined cases, and candidates are encouraged to create additional test cases, offering a holistic assessment of their intermediate programming abilities. This screening test acts as a crucial tool for pinpointing candidates who are ready for professional advancement in coding. Successful candidates will not only demonstrate proficiency in binary tree manipulation but will also prove their capability to make significant contributions to diverse coding projects.

This language-agnostic Binary Trees coding test ensures that candidates are competent in applying this data structure effectively in a programming language of their choice. Discover insights into candidates' problem-solving skills, identify individuals with strong intermediate coding expertise, and form a capable coding team that aligns with your organizational goals.

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.
