Additional Information on GCA

Essential details about the General Coding Assessment - what it is, why it matters, and how to prepare for success.

Learning Objectives

  • Learn the importance of the GCA for your career
  • Recognize the scoring system and requirements
  • Know when and how often to take the assessment

GCA Skills

  • Prepare effectively for the technical requirements
  • Develop strategies for tackling test tasks
  • Improve problem-solving under time constraints
  • Track progress and identify areas for improvement

What is the GCA?

  • The GCA or General Coding Assessment is a standardized test that measures core programming and computer science knowledge.
  • The Coding Score obtained from the test is a measure that is intended to give recruiters, hiring managers, and test-takers an overall view of:
    • test-taker's code-writing and problem-solving skills
    • the ability to produce clean code and
    • the ability to write code at a reasonable speed
  • Test takers can choose any programming language of their choice to complete the tasks.

The GCA Experience

The GCA is delivered through the CodeSignal platform and consists of four programming tasks of increasing difficulty. You'll have a set amount of time to complete as many tasks as possible, with each successful solution contributing to your overall Coding Score.

The test is designed to assess not just your knowledge of programming concepts, but also your ability to apply them to solve practical problems efficiently and produce clean, maintainable code.


When Should I take it?

Test-taking can be nerve-racking; we get it! But we at BloomTech are here to help and support you along the way. That is why we recommend that you take the GCA as often as permitted.

Taking the GCA many times will help you improve your score and prepare you for the test-taking environment and make you feel more comfortable with the process.

There are other benefits to taking the GCA as often as possible: it helps you prepare for job interviews and gives you a flavor for the types of questions you'll be asked. For this reason, we've blocked time during the learning journey allowing you to take the assessment at least one time in each unit. It would help if you also planned on taking it every four weeks after you graduate while you look for a job.

Remember: You can only take the actual GCA test every two weeks after a cool-off period. The cool-off period begins when you submit the GCA test. If you submit at 5 pm, you can only retake the assessment in 2 weeks at 5 pm or later.

Recommended GCA Timeline

  • During your BloomTech program: At least once per unit
  • After graduation: Every 4 weeks during job search
  • Before interviews: 1-2 weeks before technical interviews
  • After significant learning milestones: To gauge improvement

Why Does the GCA matter to me?

If you are interested in working at a FAANG company, you absolutely need to pass the GCA. But even if you are not interested in a FAANG company, you will likely need to pass something similar at most companies - large, small, or startups. So taking the GCA helps prepare you for interviews that include a whiteboard/algorithm test as part of the interview process.

Industry Recognition

The GCA Coding Score has gained recognition across the tech industry as a standardized measure of coding ability. Companies use this score as part of their technical screening process to efficiently identify candidates with the necessary coding skills.

Companies That Value GCA Scores:
  • Major tech giants (Google, Facebook, Amazon, Apple, Netflix)
  • Fast-growing startups
  • Financial technology companies
  • Healthcare technology organizations
  • Enterprise software companies

How to Prepare and What Does the Coding Score mean?

While the GCA assessment has four tasks, we encourage you to prepare for Task 1 and Task 2. If you solve Task 1, your Coding Score will be from 650-674. If you solve Task 2, you will receive a Coding Score of 688 - 712.

A minimum score of 650 is required, which you will receive by solving Task 1.

Here is a breakdown of what you need to know to solve Task 1 and Task 2. Remember, you can choose any programming language to complete these tasks.

Example Problem Types

// Example Task 1 Type Problem: String reversal

function reverseString(str) {
  // Solution 1: Using built-in methods
  return str.split('').reverse().join('');
  
  // Solution 2: Using a for loop
  // let result = '';
  // for (let i = str.length - 1; i >= 0; i--) {
  //   result += str[i];
  // }
  // return result;
}
