How to Conduct a Good Technical Interview

Written By Nicole Littlejohn | July 23, 2024

A well-conducted technical interview identifies candidates with the right skills and leaves a positive impression, enhancing the company’s reputation in the competitive tech job market. 

This article provides key strategies to sidestep common interview pitfalls and create a successful technical interview process to help you secure your top talent. Let’s dive in.

1. Prepare Thoroughly

Understand the Role

Before diving into interviews, it’s crucial to thoroughly understand the job requirements and key skills. This involves collaborating with the hiring team to define the essential skills and experiences required for the role. For example, if hiring a back-end developer, understand the specific programming languages, frameworks, and tools necessary for the job. Referencing an internal or third-party skills taxonomy can help with understanding the key skills for a role.

Prepare Relevant Questions

Create a mix of theoretical questions, coding challenges, and real-world problem-solving scenarios. Theoretical questions help assess the candidate’s foundational knowledge while coding challenges and real-world problems evaluate their practical skills and ability to apply their knowledge in real situations.

2. Create a Comfortable Environment

Set the Tone

Making candidates feel at ease from the beginning can significantly improve their performance. Start with a brief introduction about the company, the role, and what to expect during the interview. This helps set a positive tone and reduces initial anxiety. 

Minimize Stress

Interviews can be stressful, so it’s essential to minimize unnecessary pressure. Allow candidates to take short breaks and be patient during the interview. Use a conversational tone rather than a high-pressure interrogation style.

Provide Clear Instructions

Give clear and concise instructions for each part of the interview. Whether it’s a coding task or a system design question, ensure the candidate understands what is expected of them. Clear instructions help candidates focus on showcasing their skills rather than deciphering the question.

3. Focus on Problem-Solving Skills

Real-World Problems

Use technical problems that reflect real-world challenges the candidate will face on the job. This will test their problem-solving skills and give them a glimpse into the kind of work they will be doing. This approach will also serve   For example, instead of abstract algorithmic problems, use scenarios that involve debugging a piece of code or designing a small system.

Understand Their Approach

Evaluate the candidate’s approach to problem-solving rather than just the final solution. Observe how they break down the problem, their thought process, and their ability to adapt if they hit a roadblock. This provides insight into their analytical and critical thinking skills.

Interactive Problem-Solving

Incorporate pair programming or collaborative problem-solving sessions to observe teamwork and communication skills. This can be particularly effective in assessing how well a candidate will integrate with your existing team and handle collaborative projects.

Ask System Design Questions

The ability to architect engineering systems is a key skill for many technical roles. As such, system design questions are crucial for evaluating candidates’ ability to architect solutions. Ask candidates to design a system or component relevant to your business needs, such as a scalable web application or a microservices architecture. This assesses their high-level thinking and ability to handle complex projects.

4. Assess Soft Skills

Communication Skills

Evaluate how well the candidate communicates complex technical concepts. Good communication skills are essential for collaboration, especially in roles that require interaction with non-technical stakeholders. Look for clarity, coherence, and the ability to explain their thought process effectively.

Team Collaboration

Assess the candidate’s ability to work effectively within a team. This can be done through behavioral questions that explore their past experiences and observe their interaction during collaborative tasks. Teamwork is crucial for a harmonious and productive work environment.

5. Provide Constructive Feedback

Timely Feedback

Provide prompt feedback after the interview. Candidates appreciate timely responses, as they show respect for their time and effort. Whether they move forward in the process or not, timely feedback maintains a positive candidate experience. This is key, as a report by IBM found that a positive Experience makes candidates 38% more likely to accept an offer.

Specific and Actionable

Give specific and actionable feedback, highlighting both strengths and areas for improvement. Constructive feedback helps candidates understand their performance and how to improve, fostering a positive relationship even if they aren’t selected.

6. Continuously Improve the Process

Solicit Candidate Feedback

Gather feedback from candidates about their interview experience. This can provide valuable insights into what works well and what needs improvement. Use surveys or follow-up calls to collect this feedback.

Review and Iterate

Regularly review and iterate on the interview process based on feedback and outcomes. Identify patterns in candidate performance and feedback to make data-driven improvements. This continuous improvement approach ensures your interview process remains effective and competitive.

Train Interviewers

Ensure interviewers receive continuous training to stay up-to-date with best practices and techniques. Provide workshops or resources on effective interviewing skills, unconscious bias, and the latest industry trends. Well-trained interviewers are crucial for maintaining a high-quality interview process.

Conclusion

A successful technical interview hinges on thorough preparation and clear communication. Candidates value companies that respect their time and expertise. Tech companies can build a strong reputation and network by going beyond standard Q&A sessions to assess soft and technical skills, offering constructive feedback, and continually refining their interview processes.
