What is CodeSignal?

CodeSignal is a technical interview solution. According to the vendor, companies of all sizes already use CodeSignal’s Pre-Screen and Interview products to tap into underrepresented pools of candidates, increase speed-to-hire, and increase candidate pipeline yield. Studies have shown that companies who use pre-hire screenings see turnover rates reduce by 39%.

CodeSignal uses technology to predict a candidate’s interview performance. CodeSignal’s predictive assessments go beyond testing only for data structures and algorithms, instead they dive deep into subject-specific assessments. Assessments on CodeSignal’s platform support 38+ programming languages, provides an advanced real-world coding environment, coding scores, and utilize a proprietary AI-powered plagiarism check.

Overview of CodeSignal Features

CodeSignal offers tests in 38+ programming languages in a real life coding environment. Per the vendor, their platform is a “flight simulator for developers” that allows candidates to utilize familiar tools to edit, run and debug their code.

CodeSignal offers keystroke playback and an automated plagiarism checker. The ability to play back the candidate’s keystrokes means that their work can be evaluated by multiple members of the hiring team without the hassle of everyone attending the assessment live. Their AI plagiarism checker searches for suspicious results, such as similarities in candidate responses.

CodeSignal’s assessments can assist companies looking to diversify their teams. Companies can replace a resume screen, and the unconscious bias it may bring, with a coding assessment. Using assessment scores allow them companies to evaluate candidates purely on skill rather than any other factor.

Coding Tests

CodeSignal divides different coding tests up into unit test frameworks that assess a person’s technical skills. Examples of unit test frameworks include:

  • NUnit for .NET Framework

  • xUnit or NUnit for .NET Core

  • JUnit for Java

  • Mocha/Chai for JavaScript

  • PHPUnit for PHP

  • unittest for Python

  • RSpec for Ruby

  • UI tests using Galen

  • UI functionality tests using Puppeteer

Assessments can be set to run in a specific language, or can be language agnostic so that the candidate can complete the test in their preferred language.

Testing job-specific skills allow for companies to pre-screen based on candidate skills and helps to improve the interview to hire ratio, since only qualified candidates will be offered interviews.

Coding Interviews

Companies can use CodeSignal for more than just their screening assessments, as the platform also allows for coding interviews and whiteboard sessions. CodeSignal’s coding interview options are suitable for in-person or virtual interviews. Companies can choose interview tasks from a pre-existing library, or can easily import custom tasks from GitHub.

Using CodeSignal’s interview tool, companies can see how candidates interact with the tools they will use every day on the job and make more informed hiring decisions. Team members can interact with the candidate to evaluate their approach to solving problems.

I use CodeSignal in order to prep for interviews within the software engineering field. This product helps to prep for tech interviews while simultaneously allowing companies to pre-screen candidates in an effective manner. CodeSignal gauges the technical competencies of candidates by asking them four tech questions and then deriving a score based on a multitude of factors like how fast they solve the question and how many test cases they pass etc. This score will then be sent to companies along with a report which is in theory supposed to identify whether candidates are competent enough technically to be moved into the next round. As it pertains to my use case, I was looking for software engineering internships in the summer, and tons of companies used this platform to screen candidates so whether I wanted to or not, it was in my best interest to practice and become familiar with the platform as much as possible.

As an aspiring software engineer, I have used CodeSignal over the past several months to help me prepare for technical interviews which evaluate my technical problem-solving skills. I have also used CodeSignal to complete technical challenges for various companies to help them make decisions regarding my candidacy. In particular, I have utilized the "interview practice" section extensively to prepare for particular areas where I require improvement.

CodeSignal is used early on in the interview process to assess software engineers's technical acumen, algorithmic knowledge and overall fluency in a specific coding language. The candidates generally get sent 2 to 3 questions to complete with a specific amount of time. Any candidate with a good score gets to continue the process where they will be further assessed by engineers.

At Borderless we are hiring a world-class engineering team to build a global hiring and payments platform. As a startup without any dedicated recruiting personnel, CodeSignal is instrumental in allowing us to qualify and interview candidates.

We use CodeSignal for both screening applications at the beginning of the hiring process, as well as for live coding interviews in the final stages of the process. It is very convenient to have a bank of questions to draw from. We also use it to create custom tests and exercises.

The platform gives a great candidate experience in that the editor is easy to use. It is easy to define and run test cases. It is easy to share the editor and IDE between the candidate and the interviewer. We have received a lot of positive feedback from candidates on the interview experience.

I interviewed with many companies with CodeSignal. It was the best software I have used for conducting and participating in coding reviews. It’s intuitive and has a lot of great features, as well as maintains a clean interface. It gives a very good environment for coders of all skill levels.

CodeSignal is the ideal tool to implement diagnostic tests for prospective hires and current employees seeking promotions. We did not have the bandwidth to set up an internal system for the aforementioned testing; CodeSignal covers this use case for our business. Our scope of usage can be summarized as “knowledge and proficiency testing framework”.

I use CodeSignal for technical interviews and coding interview practice. The product is beneficial for software engineers who want to brush up on their skills. Companies often send CodeSignal technical interviews to screen their candidates, and CodeSignal also offers services to allow users to complete practice questions on their websites.

I used it for a coding assessment for Roblox to test my coding skills. This helped Roblox to assess how much coding I knew and know whether or not I would be a good fit for the role based on their expectations for what a good candidate for the role could do.

I used CodeSignal as practice for interviews as well as performing the actual interview. When using CodeSignal, the evaluation is purely performance-based and automated, which reduces the likelihood of biases that may influence traditional interviews. By using their platform for both practice and actual interviews, I was able to become more comfortable with the types of problems I would encounter.

I didn't use it in my organization; I used it as a person attempting to get into Zoom for a software engineering position. However, it did act as a good way for zoom to assess my capabilities, and for me to practice coding problems and gain practical experience for other engineering positions, too.

As a student in engineering, we had to conduct various labs. In the case of code signals, our operating system lab involved installing the program Keil vision which lets you program the board. I, like many other engineers, purchased an Apple Silicon computer recently. Because of that, native support for Keil did not exist, meaning I would have to remote into a Windows computer or do various other expensive options. Code Signals was a good mix where it was very affordable and a one-time purchase (without updates) and allowed me to complete the lab. I would highly recommend it.

The platform is amazing for new coders and people who want to learn to code. The use case lies pretty much in all IT organizations who want to attract good coding talent.. an amazing platform for preparing for coding interviews and for organizations who want to conduct coding interviews. I was amazed by the platform's UI when I first used it for one of my coding interviews.

I currently use CodeSignal to prepare for my coding interviews since many big companies use this platform to conduct their own technical assessments. It is a great way to prepare since you have a real feeling of the experience, you get asked similar type of questions, get to interact with the interface and in addition to that, you have to complete within certain amount of time.

I'm just a user. I had to use it for taking coding assessments for various different companies. The business problem that code signal addresses is that it helps out companies with automating or filtering candidates based on code signal performance. This indicator will allow them to move faster with their interview process.

I've used it in the interviewing process for my company for the process of hiring when I applied for the job and we are still using it for the purpose of hiring other candidates. It's mainly used to find out interesting coding problems and given to the candidates for solving.

We used Codesignal during our interview process, which allowed us to effectively and quickly evaluate candidates for our core software engineering requirements. Especially for a startup with very few resources, it becomes imperative to have correct filtering tools at your disposal to automatically reduce the pool of applicants to invest in the interview time of the engineers; Codesignal helped us achieve this and scale our team within a month.

We use CodeSignal to enable easy code demonstration between current and future employees. The problems it addresses deal with creating a bridge between two users to allow code to be shared and displayed easily. Most use cases deal with interviews and new hires, but code demonstration is applicable to current employees as well.

Codesignal helps us select interns. We apply tests for them, and it provides valuable information about the skills of the candidates. This method allows us to concentrate on social skills rather than technical skills. And it also prevents candidates who are not ready to be part of our team from reaching presential interviews.

I use it to solve home assignments and review my code, and in general, I use it to solve multiple problems to improve my problem-solving techniques and mindset as well I use it to practice for my interviews. The product offers many questions that appeared in many companies, and it is well organized and helpful, so I can take questions from there and practice them or interview candidates with those questions.
