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.

Getting a job with CodeSignal!
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.
- CodeSignal is very effective at giving companies a third party way to efficiently screen candidates before moving them into their next rounds of interviewing
- CodeSignal is effective at scoring and judging a candidate's technical competence with a reasonable margin of error
- CodeSignal has a great support team that responds very quickly and handles issues adeptly
- There have been some loopholes identified in terms of approaching the assessments, which can potentially compromise the integrity of the assessment.
- CodeSignal's biggest problem for me is that you can't take an assessment again. You have to wait 14 days. This is tough because if you do a test for one company and you don't like your score, your only options are to send the bad score or wait to take another test which can be problematic due to the strict deadlines some companies impose.
- CodeSignal could use a better way to prepare for the assessments within the website. Maybe like a 'module' on how to approach the test etc. This is because CodeSignal, while providing similar questions like the Leetcode website or the like, will occasionally ask questions that are far different from what is typical in tech interviewing websites.

Good but will benefit from continued improvement
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.
- Variety of questions separated reasonably into different categories.
- Organized and useful courses.
- Clean and easy-to-use online code editor.
- CodeSignal homepage can be difficult to use; the "recommended next task" isn't always useful or optimal.
- A hidden dropdown menu underneath the brand logo can be hard to find; I had difficulty finding the "interview practice" button. Would be preferred to keep it on the top bar where "my profile", "test center" etc are.
- I don't believe that the CodeSignal currency is useful; it seems to be an unnecessary distraction.

CodeSignal is good for assessing junior engineers
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.
- Testing the skills and knowledge of junior engineers
- Lets reviewers see what the candidates wrote while the exercise was happening and provides an indication of the candidate's thought process
- In my opinion, UI is really bad
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.

CodeSignal - All the right signals!
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”.
- Easily Understood UI/UX
- Wide variety of testing options
- High availability
- Better post-examination analytics

CodeSignals for University Labs.
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.
- Cheap.
- One Time Purchase.
- Maybe UI.
- Have a clearer list of what apps work.

Great for interview practice
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.
- User experience
- Provide real interview questions
- Feedback on your results
- Make discussion section
- Have their questions divided into more sections

This is really helpful if you want to scale quickly.
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.
- Developer assessment.
- Skill evaluation.
- Coding score.
- Web Interface.

CodeSignal : Some good, Some bad.
My work does not require me to use CodeSignal. I have been using it to practice coding problems and prepare for my interviews. This has been useful for me to do a guided set of problems belonging to a coding category.
- It has IDE, which helps you put debugging statements and run code which helps to find bugs or verify results when practicing coding.
- It also has dedicated Java Spring-related questions that mimic what is being worked on in the real-world (Creating APIs etc.).
- It definitely lets import/support more libraries than other coding platforms out there.
- It needs to expand its use case to another actual working environment beyond Java and spring (not sure if it supports everything today).
- The ones which have 3 or 4 questions to be completed within 1 hour is really bad for people who code in Java and provide a HUGE advantage to people who code in python.
- Modify the question based on the language chosen; only then the time limit will make sense.

Code signal as an engineering user
Used it as an interview tool to assess in a trusted and secure manner the performance of me as a software engineer. This took guaranteed I didn't cheat, maintaining trust between my interviewer and I. It also provided me with amazing coding tools to make my experience as smooth as possible.
- Coding tools for developer
- Monitoring tools for interviewer
- Programming language diversity
- Tutorials are confusing

Awesome Product!!
Amazon is always expanding and hiring new professionals as per the team's requirements. Since there are thousands of applicants for each open position, CodeSignal helps us to acquire the right individuals that have the potential to match the bar at Amazon. The flexibility of CodeSignal allows us to prepare a good screening round for candidates. The overall interface and experience of CodeSignal also allow candidates to give their best.
- Good UI/UX - Allows candidates to feel comfortable while attempting the test.
- Good Interface - Good design of the code editor enables candidates to focus on solving the problem.
- Nothing for now.

I got the job!
I used it to prep for the screening challenge and interview. I did a lot of the arcade challenges and it helps me remember/sharpen my algorithm skills. I also used it during the screening process - this is where I took a four part coding challenge on webcam. During the interview, I used a collaborative feature where the manager could watch me and code with me real time. I have found CodeSignal to be incredibly important and without it I would've never transitioned from being in the public sector to now being a software engineer.
- Easy to use
- Looks pretty
- Widely accepted
- Multiple language options
- Diverse algorithms
- Helping to understand the time requirement
- Providing a better understanding of edge cases
- Sometimes need more explanation in the prompts

Incredible recruitment sourcing
CodeSignal helps sort out interview applicants by examining them on the skillset required on the job. While recruiting, some services require experiences as priority above word of mouth, cover letters and CVs. Thus, a demonstration of one's capabilities when giving the task at hand. In instances of recruitment of such services CodeSignal provides an additional filter to sort out the best among candidates.
- The simulation of the test sessions with the practice sessions integrates the user well with the platform with use cases.
- The test questions involved are up to par with industry standards and makes one deliver an expression of his knowledge in a language.
- CodeSignal provides a platform to improve your knowledge in any programming language by assigning badges to accomplishments keeping users motivated.

A complete package for assessment
CodeSignal is the technical assessment platform that we use to hire new employees. The CodeSignal assessments are given as part of the interview process. We use CodeSignal to assess the aptitude in programming skills from the CodeSignal assessment score. As the score is generated on aspects such as the candidate's problem-solving ability and speed, the CodeSignal assessment serves as a good measure to judge a candidate before that person is called for the next round of interviews.
- Option of proctored/unproctored assessment
- Uniform structure of assessment
- Variety of problem sets to choose from
- Score certification process to check for malpractices
- Code editor should be more responsive for auto suggestions
- Practice environment should be located in such a way that it should be found easily
- A transparent and publicly available pricing

Review on CodeSignal!
I have used CodeSignal to practice for coding interviews. I have seen many companies use it for their online coding assessment round and I really like the UI code signal. Also, I love how it evaluates the time complexity and the test cases which test for all possible edge cases.
- Coding Assessment
- Code analysis
- Performance rating
- Show time complexity for complex codes.
- Show lines of code which can be omitted.
- How to make code more efficient.
I used CodeSignal to train myself for coding interviews. The tool allows me to set a training program, a schedule and then I can follow it throughout the weeks. I also realized interviews with another company using CodeSignal as their tool of choice for the coding & algorithms section.
- Coding interview training
- Coding interviews with interviewers
- Comparison of solutions of algorithms
- Good explanation and examples of algorithms
- Some algorithm have problems in the expected resolution (they don't work)
- There could be more shortcut options in the code editor

An Opportunity to Grow Yourself
I have been using CodeSignal for almost 1 year. This is a great way to test your problem-solving and algorithm implementation skills. I started using CodeSignal when I applied for an internship and have been using it ever since. In addition to regular exams, we also offer algorithmic and data structure-based questions and data science modules. The coding environment is so stable and intuitive that most people can understand it without any problems. Numerous exercises to help improve your algorithm and data structure skills. The final assessment helps candidates track their progress by identifying their strengths and weaknesses. My coding abilities have vastly increased and continue to assist me in improving. It smooths down the screening process, and because the administered appraisals are verified by CodeSignal, the results of the evaluations are guaranteed to be accurate. Because of their verifiable experience, more people can be hired.
- Organizing questions based on the implementation and data structures used.
- Customer service and user interface are both excellent.
- A diverse set of questions that is regularly updated.
- Minimizes the number of candidates by screening through.
- The platform should provide candidates with detailed feedback, allowing them to identify areas for improvement if necessary.
- Furthermore, despite the fact that the assessment is complete, the platform prioritizes speed. In order to finish the assignment on time, people may be forced to forgo quality or desired output.
- They should improve the question selection procedure, as some of the questions are too long to finish in the allocated time.
