As an asynchronous assessment, it allows candidates to demonstrate their skills without the pressure of real-time observation while still providing valuable data points on their technical capabilities.

Select 2-3 coding problems that reflect real challenges our engineers face, at an appropriate difficulty level for the seniority of the role. The problems should test algorithmic thinking, code organization, and attention to detail without requiring specialized knowledge outside our tech stack.

Review submissions thoroughly, assessing not just correctness but also code style, efficiency, edge case handling, and documentation. Consider providing a rubric to candidates so they understand how they'll be evaluated.

You should provide clear instructions, including:

Time expectations (both the time limit and expected effort)
Submission format requirements
Permitted resources and tools
Evaluation criteria

Directions to Share with Candidate

"We'd like you to complete a technical coding assessment that helps us understand your programming approach, problem-solving skills, and code quality. You'll receive 2-3 problems to solve using [preferred language or candidate's choice of languages]. This assessment is asynchronous, meaning you can complete it at your convenience within the next [timeframe, e.g., 48 hours].

You'll have up to [time limit, e.g., 90 minutes] to complete the problems once you start the assessment. We expect most candidates will need 60-75 minutes, but we provide extra time to reduce pressure.

Please approach this assessment as you would a real work task:

Write clean, maintainable code
Include comments where appropriate
Handle edge cases
Consider performance implications
Include basic test cases when possible

Feel free to use standard libraries but avoid using AI coding assistants. You're welcome to reference documentation but should not search for direct solutions to the problems.

Submit your solution via [submission method] when complete. We'll evaluate your code based on correctness, efficiency, readability, and your approach to problem-solving."

Example Coding Problems

Problem 1: String Manipulation

Implement a function that takes a string and returns the most frequently occurring character. If multiple characters have the same frequency, return the one that appears first in the string. Consider edge cases like empty strings or strings with only one character.

Problem 2: Data Structure Implementation

Implement a cache with a Least Recently Used (LRU) eviction policy. Your implementation should support the following operations with the specified time complexities:

get(key): Get the value of the key if the key exists in the cache (O(1))
put(key, value): Set or insert the value if the key is not already present (O(1))
When the cache reaches its capacity, it should invalidate the least recently used item before inserting a new item

Reference Calls

Directions for Conducting Reference Checks

Reference checks provide valuable third-party perspectives on the candidate's past performance, working style, and growth areas. They help validate impressions from the interview process and uncover potential concerns.

Conduct at least two reference calls, ideally with direct supervisors or senior colleagues who worked closely with the candidate. When possible, include at least one reference not provided by the candidate.

Approach these calls as professional conversations rather than interrogations. Begin by explaining the role the candidate is being considered for, then ask open-ended questions that encourage detailed responses.

Take detailed notes during the call, focusing on specific examples rather than general impressions. Listen for consistency with what the candidate shared during interviews, as well as any new insights into strengths or development areas.

If you hear concerning feedback, ask follow-up questions to understand the context fully before drawing conclusions.

Frequently Asked Questions

What technical skills are most important for success in this Software Engineer role?

While we value proficiency in our tech stack, we prioritize strong fundamentals in data structures, algorithms, and system design. A solid understanding of programming concepts and problem-solving abilities are more important than expertise in specific languages or frameworks, as these technical details can be learned. We're looking for engineers who can adapt to different technologies as our needs evolve.

How do you evaluate candidates who are strong technically but may have less developed communication skills?

We believe effective communication is essential for engineering success at [Company]. While we recognize that technical skills are core to the role, an engineer's ability to collaborate, explain technical concepts, and participate in discussions directly impacts team effectiveness. We look for candidates who demonstrate clear technical communication during interviews, even if they're not the most outgoing personalities. We can work with candidates who show awareness of communication as a growth area.

What if a candidate performs well in most areas but struggles with system design?

We evaluate candidates holistically across all interview stages. For junior to mid-level roles, we may place less emphasis on system design abilities if other technical and behavioral aspects are strong, as these skills often develop with experience. For senior roles, system design capabilities are more critical. In all cases, we consider whether the candidate demonstrates the aptitude and learning mindset to grow in areas where they currently have gaps.

How do you ensure the interview process is fair and reduces bias?

Our structured interview process is designed to evaluate all candidates against the same criteria using consistent questions and scorecards. We train interviewers to focus on observable behaviors and concrete examples rather than gut feelings. Having multiple interviewers evaluate each candidate from different angles helps provide a more complete picture and reduces individual bias. We also regularly review our process for potential improvements.

Should we prioritize candidates with experience in our exact tech stack?

While familiarity with our technologies can reduce ramp-up time, we generally prefer candidates with strong fundamentals who demonstrate the ability to learn quickly over those who know our specific stack but have weaker core skills. The exception might be roles requiring specialized expertise where domain knowledge would take significant time to acquire. Our experience shows that talented engineers can become productive in new technologies relatively quickly.
