Real-time coding challenges are an incredible way to assess technical skills, problem-solving abilities, and how candidates handle pressure. But throw in the dynamics of offshore developers (different time zones, languages, and technical setups) and it becomes a bit trickier.

But it can be turned into a smooth, productive experience. 

This guide will walk you through everything you need to know about conducting effective real-time coding challenges with offshore developers.

What is a Real-Time Coding Challenge?

A timed coding challenge is an assessment or competition where programmers solve coding problems within a set time frame, typically in a live or interactive environment. This can take place during interviews, hackathons, or on online coding platforms.

A few key features of real-time coding challenges include:

  1. Live Coding: Participants write code while being observed, either by interviewers or through a shared platform.
  2. Time-Bound: Challenges are often limited to a specific duration, testing both coding speed and presence of mind.
  3. Problem-Solving: Candidates tackle algorithmic or data structure problems, demonstrating their coding skills and logical reasoning.
  4. Immediate Feedback: Results or feedback on the code can often be received right away, allowing for learning and improvement.

These challenges evaluate a candidate’s programming skills, problem-solving abilities, and thought processes in a dynamic setting.

Why Real-Time Coding Challenges Matter

Resumes and portfolios only tell part of the story. Real-time coding challenges let you see:

  • Problem-solving in action: How does the developer approach a problem under pressure?
  • Communication skills: Are they able to explain their thought process?
  • Adaptability: How do they handle unexpected hurdles?
  • Collaboration readiness: Are they open to feedback and discussion during the challenge?

Real-time challenges simulate actual work scenarios, giving you a clear picture of whether the candidate is a good fit for your team.

How to Conduct a Real-Time Coding Challenge

1. Preparing for the Challenge

You need to make sure the challenge is both fair and effective.

Steps to prepare:

  • Define the goal: Are you testing problem-solving skills, familiarity with a specific tech stack, or speed and accuracy? 
  • Choose the right platform: HackerRank, Codility, or CoderPad provide environments designed for real-time coding.
  • Prepare tasks in advance: Tailor problems to the role. A front-end position might focus on UI challenges, while a back-end role could center on algorithms.
  • Set clear criteria: Decide how you’ll evaluate the candidate: coding efficiency, logical approach, or communication.

Example: For a front-end role, you might ask the candidate to create a responsive component or debug a broken UI feature.

2. Communicating Expectations Clearly

For offshore candidates, clarity is crucial to avoid miscommunication.

What to communicate:

  • Challenge format: Explain if it’s a live coding session, pair programming task, or timed problem-solving.
  • Duration: Let them know how much time they’ll have to complete the challenge.
  • Tech requirements: They must be set up with the right tools (e.g., IDEs, browsers, or terminal access).
  • Evaluation criteria: Be upfront about how their performance will be judged.
  • Time zones: Coordinate a time that works for both parties without causing undue stress.

Tip: Send a prep email with all the details and a test link to ensure they can access the platform.

3. Creating a Comfortable Environment

A relaxed candidate performs better.

How to put candidates at ease:

  • Start with an introduction: Share a bit about your company, team, and role they’re interviewing for.
  • Warm up with small talk: A quick chat about the weather or their favorite tech tool can help break the ice.
  • Explain there’s no “perfect solution”: Emphasize that you’re more interested in their approach than whether they get it 100% right.

Example: “This challenge is less about the final result and more about seeing how you think through problems. Feel free to talk us through your thought process as you go.”

4. Designing an Effective Challenge

Not all coding challenges are created equal. Make sure yours is engaging, relevant, and fair.

Best practices:

  • Make it role-specific: Tailor tasks to the day-to-day responsibilities of the position.
  • Focus on problem-solving: Skip obscure trivia questions about algorithms they’ll never use on the job.
  • Keep it realistic: Don’t overload the challenge. It should be completable in the given time frame.
  • Add room for creativity: Include open-ended elements where candidates can showcase their unique skills.

Example: Ask a back-end developer to build an API endpoint and handle potential edge cases.

5. Managing Time Zones and Scheduling

Coordinating with offshore developers means working around time differences, but it doesn’t have to be a headache.

Tips for smooth scheduling:

  • Use scheduling tools: Apps like Calendly or Doodle help you find overlapping availability.
  • Be flexible: Try to accommodate their local working hours as much as possible.
  • Communicate ahead: Give at least a few days’ notice to allow candidates to plan their schedules.

Tip: If time zones are drastically different, consider pre-recorded challenges followed by a live review session.

6. Conducting the Challenge

The actual challenge session is where the real thing happens.

Steps to run it effectively:

  1. Test the setup: Start with a quick check to ensure the candidate’s connection and tools are working.
  2. Introduce the challenge: Walk them through the problem statement and clarify any questions before starting.
  3. Let them work: Avoid micromanaging, but stay present in case they need clarification.
  4. Encourage communication: Ask them to think aloud so you can follow their logic.
  5. Respect time limits: Stick to the planned duration to avoid unnecessary stress.

Pro tip: Take notes during the session to review their strengths and areas for improvement later.

7. Assessing Performance Fairly

Evaluation should be thorough yet unbiased.

What to look for:

  • Code quality: Is it clean, efficient, and maintainable?
  • Problem-solving approach: Did they consider edge cases and prioritize logical steps?
  • Communication: Were they able to explain their thought process clearly?
  • Adaptability: How did they handle challenges or feedback during the session?

Avoid common pitfalls:

  • Overemphasizing speed: Faster isn’t always better. Quality matters more.
  • Nitpicking syntax: Focus on the overall approach, not minor typos.

Example: A candidate might not solve the problem fully but could demonstrate excellent debugging skills and logical reasoning.

8. Providing Constructive Feedback

Feedback is a two-way street. It helps candidates grow and reflects positively on your company.

How to give great feedback:

  • Be specific: Highlight what they did well and where they can improve.
  • Stay positive: Frame critiques as opportunities for growth.
  • Ask for their input: Invite them to share how they felt about the challenge.

Example: “We really liked how you approached the problem systematically. One suggestion would be to watch for edge cases like X in future scenarios.”

9. Refining Your Process Over Time

Your coding challenge process should evolve based on feedback and experience.

Ways to improve:

  • Collect candidate feedback: Ask how they found the experience and whether they’d suggest changes.
  • Analyze results: Are your challenges helping you identify strong candidates effectively?
  • Stay updated: Incorporate new tools or methodologies as they become available.

Tip: Regularly review your process with your hiring team to identify gaps or inefficiencies.

Conclusion: Build a Process That Brings Out the Best

Real-time coding challenges are a powerful tool for assessing offshore developers, but the process requires care and attention. 

The goal is to assess if the candidate is the right fit for you and to build a connection. Preparing thoroughly, communicating clearly, and being fair eases the path and makes the experience effective and enjoyable for both parties.

When candidates feel valued and understood, they’re more likely to perform at their best and see your company as a place they want to be.
