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.

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

Verified User
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.
- Identifying industry needs.
- Simplifying the interview process.
- Providing a resource for job seekers.
- the flexibility of learning plans.
- The user profile should be optional.

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

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.

Great.
I used CodeSignal for an online assessment for a firm to that I applied for a summer internship. The platform was very good and user-friendly. It was very easy to navigate through the platform, and the questions were pretty good and required clarity of the concepts. It is a great platform that I will recommend.
- User friendly UI.
- Great questions.
- Easy to use.
- Compiler issues for problems.
- Switch back to previous question.
- Better editor.

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

A good experience on the platform
Code signal is a very good tool to assess coding ability with data structures and algorithms of a potential employee. It gives an excellent review of the strengths of the applicant. The wide range of questions in the system tests people on a variety of different skills that might be needed and expected out of a software developer.
- Easy assessment.
- Rarely gives repeated questions.
- Good rating after completing assessment.
- Auto complete variables.
- Auto complete commonly used syntaxes.
- Reconnect on loss of internet sometimes gives issues.

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.

Excellent Tool for Improving Coding Skills
Out of hundreds of people who apply to work at our company, CodeSignal assists us in identifying the best candidates. As far as I'm aware, it offers two types of examinations: general coding evaluations and data science assessments. We know the candidate's scores are legitimate because they are proctored and confirmed. In short, it saves time because we just have to interview a smaller number of individuals.
- The test cases are quite well-written, and the grade we earn as a result of them is very fair. Users can use a unit testing tool to perform their own unit testing, allowing them to double-check their code before submitting it.
- Intensive technical interview preparation
- The online evaluation option is an excellent approach to assess candidates.
- Simple UI for Simple Operations
- There is no specific answer for the technical evaluation round. If I can't answer the question during this time, I won't be able to find a solution. A hint generator can be used to solve the problem and learn how to solve it at the end of the task.
- I think the problem selection is a little haphazard; in a coding exam, the activities should be picked such that they can be completed within the time limit.
- More interview question samples are needed.

An amazing platform to filter intellectual candidates
CodeSignal is helpful in sorting out the best candidates, out of hundreds of candidates that apply at our company. It provides two types of assessments, as far as I know, i.e. General Coding Assessments and Data Science Assessments. Since they are proctored and verified, we know that the candidate's scores are genuine. In short, it saves time, since we have to interview fewer candidates.
- Technical Assessments
- Grading the candidates on different categories of coding
- Intensive technical interview preparation
- Sometimes the difficulty levels of the questions asked are not properly distributed and would take significantly more time to complete
- It doesn't provide us with solutions, after we have finished the assessments
- It has a cooldown period of 14 days before you can take a proctored test again, which I feel is extremely long

An Extraordinary Platform for Coding Skills Improvement
We use CodeSignal to vet potential employees. It helps us figure out which candidates have a solid grasp of computer science principles and which ones need to brush up on their technical knowledge. This is crucial since coding habits differ and can have an impact as the project scales up to production.
- Easy Operations with Simple UI
- The test cases are extremely well written, and the rating we receive based on them is extremely fair. Users can perform their own unit testing with the use of a unit testing tool, which allows them to double-check their code before submitting it.
- The online evaluation option is a fantastic way to evaluate applicants.
- Need Some Improvement in Auto Complete Feature
- A plagiarism check should be incorporated in the code.
- More code questions per data structure would be great!

Streamlining Recruitment Process
We use Code Signal to prepare for interviews for intern and full-time positions. We've spent a lot of time solving problems involving data structures and algorithms, which are crucial for any interview or assessment of any company. The puzzles on arrays, strings, linked lists, hash maps, and specific interview preparation material greatly aided us in cracking the interviews and attaining our dream jobs at our dream businesses. The preparation plan is highly extensive, and the programming questions are up to industry standards, allowing us to judge the complexity level of the challenges we might encounter during the interviews.
- Clear problem description & Edge Cases
- Candidate performance evaluation
- LeaderBoard & Rewards
- Company Interview Preparation
- Better and Interactive User Interface

CodeSignal to the rescue
The organization primarily works on the data side dealing with big data. Typical assessment platforms are not sufficient in judging the skills in areas of data or in other areas as development or full-stack. I feel CodeSignal is a complete package that supports Jupyter Notebook integrations and makes it easy to test shell scripts knowledge, as it provides a Linux environment.
- Jupyter Notebook
- Linux environment
- Collaborative editing
- Better debugger natively without installation
- Support for SRE assessment like Docker and Kubernetes.
- Preconfigured environment and no need to install again and again

Efficient way to practice for interviews!
As a student, I use it to help me prepare for technical interviews. I've provided several CodeSignal exams and believe they're really useful in predicting how you'd perform in a technical interview. Because the platform is incredibly informative and has a user-friendly layout, most of my peers utilize it for technical evaluations and interview preparation.
- Great questions for Technical Evaluations
- User friendly interface
- Point system that pushes you to complete more problems
- I suppose they should include a feature that allows us to know whether the recruiter who requested our technical evaluation opted to proceed with the interview process or rejected us and decided to move on.
- I think they should provide more listings of frequently asked questions by popular companies.
- They should at the very least provide a suggestion or a solution to the questions we couldn't answer during the technical evaluation. How are we meant to improve if you don't tell us how to do it even after the assessment?

Software Engineer
I did not use CodeSignal for my organization but I used it to prep for coding interviews. I found the feedback on the coding assessment to be very helpful. I like that assessments contain four questions instead of the typical two.
- More feedback on coding problems
- Features for beginners and advanced coders
- point system that pushes you to complete more problems
- More feedback on how scores are evaluated.
- Insight on why time should be incorporated into your score
- More lists on popular questions used by companies

- Ease of use
- UI Design
- Transparency with how scoring works
- Sharing coding scores
- More granularity with score percentiles would be nice
- Built-in programming language documentation so I don't have to worry about opening another tab and tripping the anti-cheat
- For the sake of convenience make exams due at midnight instead of exactly 2 weeks from the test being sent out.
January 15, 2022
Fun and fresh
I use CodeSignal to practice coding and for companies to test me on LeetCode-like questions. They try to portray the companies' actual intentions for the job.
- Auto-complete really helps when I am trying to remember function names.
- The UI is very user friendly and particularly easy to understand.
- There's not a lot of wiggle room for practice. We should be able to do what we want, not go through levels.
