Computer Programmer Coding Aptitude Test

The Computer Programmer Aptitude Test uses scenario-based MCQs to evaluate candidates on their ability to solve problems using logic, analytical thinking, and programming concepts. The test assesses candidates' understanding of topics such as algorithms, data structures, programming paradigms, syntax, and programming logic. Candidates are evaluated on their ability to analyze problems, identify patterns, and develop effective solutions using programming concepts, as well as their proficiency in using programming languages to write functional code regardless of the specific programming language or framework used.

Rewards Activities Order
Database Connection
Solve
A new popular app tracks the activities performed by its users and grants them rewards based on each individual's total activities performed in a year. This data is maintained in a database table (activitesinfo), with the following columns: userid, totalactivities, reward. This year, due to fundraising activity, the company has decided to further reward its users by enhancing the reward as per the following formula: If reward < = 4000, increase it by 2%, If 4000 < reward <= 8000, increase it by 4%, If reward > 8000, increase it by 6%.
The tech team has written three different scripts to calculate increment for each slab, each script is to run as a separate transaction. Here are the three scripts:
Script 1:
For users with reward <= 4000, set reward = reward * 1.02

Script 2:
For users with reward > 4000 and reward <= 8000, set reward = reward * 1.04

Script 3:
For users with reward > 8000, set reward = reward * 1.06
Each script is to be executed separately. Which of the following options will update the rewards as expected:
A: Execute Script 1 followed by Script 2 followed by Script 3
B: Execute Script 2 followed by Script 3; Script 1 running concurrently throughout
C: Execute Script 3 followed by Script 2; Script 1 running concurrently throughout
D: Execute Script 3 followed by Script 2 followed by Script 1
E: Execute Script 2 followed by Script 3 followed by Script 1

Registration Queue
Logic
Queues
Solve
We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount.
For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition.
⚠️⚠️⚠️ Note:
- The first line of the input is the length of the array. The second line contains all the elements of the array.
- The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function.
- You need to "print" the final result (not return it) to pass the test cases.

For the example discussed above, the input will be:
5
20 70 -40 30 -10

Your code needs to print the following to the standard output:
20 70 30 -40 -10

Visitors Count
Strings
Logic
Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. 
Example:

Input:
WWMMWWCCC

Expected Output: 
4W3C2M

Explanation: 
‘W’ has the highest count, then ‘C’, then ‘M’. 
⚠️⚠️⚠️ Note:
- The input is already parsed and passed to a function.
- You need to "print" the final result (not return it) to pass the test cases.
- If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’.
- If any of them have the same count, the output should follow this order - M, W, C.

Test candidates on core Computer Programmer Coding Aptitude Hiring Test topics

Programming Fundamentals: Programming fundamentals encompass the basic concepts and principles of writing and organizing code. This includes understanding variables, data types, operators, control structures, loops, functions, and debugging techniques. Measuring this skill in the test ensures that the candidate has a solid foundation in programming and can apply these concepts effectively.

Data Structures: Data structures refer to the ways in which data is organized, stored, and accessed in a computer program. This includes arrays, linked lists, stacks, queues, trees, and graphs. Evaluating this skill in the test helps assess the candidate's ability to choose and implement appropriate data structures to optimize program efficiency and solve complex problems.

Algorithm Basics: Algorithm basics involve understanding the step-by-step procedures for solving computational problems. This includes knowledge of algorithms for searching, sorting, and manipulating data. Assessing this skill in the test allows recruiters to evaluate a candidate's ability to design efficient algorithms and analyze their time and space complexities.

Technical Aptitude: Technical aptitude refers to a candidate's overall technical knowledge and competence in various programming languages, tools, and technologies. This includes familiarity with different programming paradigms, IDEs, version control systems, and debugging tools. Measuring this skill in the test helps gauge a candidate's ability to adapt to new technologies and stay updated in the rapidly changing field of computer programming.

Coding: Coding involves the practical application of programming concepts and skills to solve coding problems. This includes writing clean, efficient, and maintainable code using the appropriate syntax, language-specific features, and programming best practices. Evaluating this skill in the test ensures that the candidate can translate their understanding of programming into practical implementation to deliver high-quality software solutions.

Have questions about the Computer Programmer Coding Aptitude Hiring Test?

How does pricing work?

You can check out our pricing plans.

Can I customize the test?

Yes, absolutely. Custom assessments are set up within 48 hours based on your job description, and will include questions on all must-have skills you specify. Here's a quick guide on how you can request a custom test. You can also customize a test by uploading your own questions.

Can I combine multiple skills into one test?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify. Here's a quick guide on how you can request a custom test.

What roles can I use the Computer Programmer Coding Aptitude Assessment Test for?

Here are few roles for which we recommend this test:

  • Computer Programmer
  • Software Engineer
  • Junior Developer
  • Database Developer
  • Mobile App Developer
Can I see a sample test, or do you have a free trial?

Yes!

The free trial includes one sample technical test (Java/ JavaScript) and one sample aptitude test that you will find in your dashboard when you sign up. You can use it to review the quality of questions and the candidate experience of giving a test on Adaface.

You can preview any of the 500+ tests and see the sample questions to decide if it would be a good fit for your requirements.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

I'm a candidate. Can I try a practice test?

No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.
