What makes a great coding interview platform?
The most effective technical interview platforms strike a balance between powerful features, ease of use, and a positive experience on the candidate side. Here are a few top qualities to look for as you narrow your search:
Real-time collaboration
Live collaboration during a coding session transforms the interview from a static test into a real dialogue. Interviewers and hiring managers can observe how candidates think, troubleshoot, and communicate on the spot.
Many platforms offer integrated video, audio, screen sharing, and collaborative code editors, making it easier for teams to simulate real-world programming sessions and provide immediate feedback during a live session.
Support for a variety of technical roles
Enterprise teams often hire across a wide range of software development roles, so language and workflow flexibility is a must.
Access to multiple programming languages and a full-featured integrated development environment (IDE) makes it easier to evaluate candidates with diverse technical backgrounds—from front-end developers to DevOps engineers—all in one place. It also saves hiring teams the hassle of juggling multiple tools for a single purpose.
Candidate-friendly interface
A complicated interface shouldn’t be the reason a great developer struggles to get through an interview—or why they walk away feeling disappointed in their own performance.
Intuitive layouts and built-in virtual whiteboards feel more familiar to candidates and put the tools they need right at their fingertips. A user-friendly environment is also helpful in reducing stress and allowing candidates to focus on actually demonstrating their skills.
Templates for structured interviews
Structured interviews—where interviewers ask the same questions of every candidate, in the same order—have long been recognized as a best practice for all types of interviews. Interview templates make this easy by pre-populating your coding interview with the questions every candidate should be asked when interviewing for a specific role, regardless of who is conducting the interview. This helps create a fairer process for candidates, and ensures all your interviewers are evaluating candidates by the same criteria.
🚀 Together, these features create a smoother experience for candidates and a more reliable, scalable process for hiring teams. The right platform doesn’t just help you assess skills — it helps you hire with clarity and confidence.

Content partnership
Best-in-class coding interview tools should provide an extensive library of pre-built coding questions that interviews can pick and choose from to build role-specific interviews. At the same time, the coding interview vendor should be willing to partner with your team to create custom questions that align with your specific company context and job responsibilities.
Best practices for conducting technical interviews
Effective technical interviews go beyond assessing a candidate’s code. They prioritize real-time interaction and problem-solving so interviewers can get a sense of how the candidate would actually perform on the job.
Using tools that support integrated video and audio helps interviewers engage naturally with candidates, offer immediate feedback, and better understand how applicants approach problems in the moment.
As former Microsoft software engineer Akshay Phadké puts it, “It’s poor form to just be typing away silently for the duration of the interview.” Candidates’ explanation of their thought process is just as important as getting the right answer, and good interviewers should look for and encourage that approach throughout each session.
By following best practices, technical interviews can become a more accurate and equitable step in the hiring process.
Set clear expectations
Clearly articulating the goals and desired outcomes of the interview process helps candidates understand what is expected of them. Inform everyone about the interview format, the types of interview questions to expect, and the evaluation criteria beforehand.
Outlining the interview structure and skills assessments helps candidates prepare well and perform to the best of their abilities.
Provide constructive feedback
Providing thoughtful, constructive feedback improves the candidate experience and strengthens your hiring process. Tools that support recorded interviews make it easier for interviewers to deliver accurate feedback and offer candidates meaningful insights for growth.
No one enjoys following up an interview with total radio silence. Open the door for constructive conversation afterwards.
Make continuous improvements
Keep improving your interview process by listening to feedback and reviewing performance data. Insights from candidates, interviewers, and analytics help you spot what’s working—and what’s not—so you can make smarter, more effective hiring decisions over time.
For example, if multiple candidates flag a coding prompt as unclear or overly complex, that’s a signal to revise the challenge for better clarity and fairness. Next time, you’ll end up with a stronger candidate experience and more reliable evaluations.
Common interview mistakes to avoid
When conducting coding interviews, there are several common mistakes to avoid. These include:
❌ Failing to provide clear instructions for preparation or participation
❌ Asking different questions to candidates for the same role
❌ Not allowing sufficient time for the interview
❌ Neglecting to offer feedback (even if simple) in a follow-up
Additionally, hiring teams should be aware of potential biases and take steps to mitigate them, such as using blind hiring practices or standardized evaluation criteria. By being aware of these potential pitfalls, companies can create a fair and effective hiring process that showcases their commitment to diversity and inclusion.
