The Microsoft Codility Test evaluates coding skills and algorithmic thinking.

Designed to streamline Microsoft’s recruitment process, the Microsoft Codility Test assesses candidates' ability to solve real-world problems efficiently. 

Candidates can prepare using coding practice platforms and mastering programming languages. It's an integral tool in selecting skilled software engineers for Microsoft's diverse roles.

What Is the Microsoft Codility Test?

The Microsoft Codility test refers to a coding assessment platform used by Microsoft and many other companies for evaluating the technical skills of job candidates, particularly in software development roles. 

Codility provides a platform for employers to create coding challenges and tests that candidates can complete online. These challenges typically involve solving coding problems, implementing algorithms and demonstrating programming proficiency.

The Codility test is designed to assess a candidate's problem-solving skills, algorithmic thinking and coding abilities in languages like C++, Java, Python and others. 

Candidates are given a set of coding problems to solve within a specified time frame. 

They write their code directly in the Codility interface and submit it for evaluation. The platform then checks the correctness and efficiency of the solutions provided by the candidates.

The test is an online timed coding test comprised of two to four coding questions.

The difficulty of the Codility test will depend on the role being applied for.   Although there are only two/three questions set, the questions are a rigorous assessment of a candidate's coding ability. 

Candidates are usually provided with between 60 and 90 minutes to answer the questions set.

The primary purpose of the Microsoft Codility Test is to evaluate the technical skills and capabilities of job candidates, particularly those applying for software development or programming roles within Microsoft, such as those labeled as a software internship, an SDE-1 role or an SDET role.

The test serves several important purposes:

Technical Assessment

The test assesses candidates' coding skills, problem-solving abilities and algorithmic thinking. 

It helps Microsoft understand how well candidates can translate their technical knowledge into practical code.

Initial Screening

The Codility Test is often used as an initial screening tool. Candidates performing well on the test are more likely to proceed to the following stages of the interview process, such as technical or on-site interviews. 

The test is quick to administer and for candidates to complete compared to traditional technical interviews. This allows Microsoft to assess a larger number of candidates efficiently in the early stages of the recruitment process. 

Efficiency and Performance

The test includes time and space complexity considerations. This helps Microsoft assess the correctness of a candidate's solution and its efficiency. 

Writing code that performs well in terms of speed and memory usage is crucial in real-world software development.

Shortlisting Suitable Candidates

Microsoft, like many other tech companies, receives a large number of job applications. 

Coding tests like Codility help filter out candidates who may not possess the necessary technical skills early in the hiring process, allowing Microsoft to focus its time and recruitment efforts on only those candidates with the required skills and abilities needed for the role. 

Standardized Evaluation

Coding assessments provide a standardized way to evaluate candidates across different backgrounds and experiences. It's a fair way to compare candidates' technical abilities, regardless of their educational backgrounds or work histories.

Job Role Fit

Different roles within Microsoft require different levels of technical proficiency. 

The Codility test helps Microsoft assess whether a candidate's skills align with the requirements of the specific role they are applying for.

It's worth remembering that while the Codility test is an essential factor in the hiring process, it's not the only determinant of a candidate's suitability for a role. 

The Codility test is followed by other stages of interviews and assessments to evaluate a candidate's technical and soft skills in more depth. 

What Is the Passing Score for the Microsoft Codility Test?

The Microsoft Codility test is used in the early stages of the recruitment process for several vacancies at Microsoft at different experience levels. 

This means that the Microsoft Codility test passing score is dependent on the level of experience and seniority of the role a candidate has applied for. 

For more experienced positions, the test's difficulty level is greater than for roles that require a lower level of experience. 

Candidates that score 100% on the test pass the Microsoft Codility test. 

Those who score between 60% and 99% may be considered for the later stages of the recruitment process, dependent on further review by the Microsoft recruitment team. 

Recruiters will consider information gained from other parts of the recruitment process in making their decision. 

Candidates that score below 60% in the Microsoft Codility test are deemed to have been unsuccessful in the assessment and are eliminated from the recruitment process.

Microsoft Codility Test Questions

Some examples of Microsoft Codility questions are noted below:

Example Question

Example Question One

‘Find the length of the longest sub-sequence from the given array A of integers.’ 

Input: N[] = [12,5,14,1,4,3]

Note that the elements in this sub-sequence must be consecutive integers. They can also be consecutive numbers in any order.

Example Question

Example Question Two

Given the integer N and the list ARR, sort the array using the bubble sort algorithm. N = 7 ARR[] = 5, 2, 10, 4, 3

Output: 2, 3, 4, 5, 10
