One of the most common questions we get at Silver.dev is how to structure a technical interview process for startups.

In this article, we’ll break down the different types of technical evaluations, their pros and cons, and how to design a hiring process that aligns with your company’s needs and budget. We’ll also discuss how to adapt your process to evaluate international talent effectively.

The Key Components of a Technical Interview

A strong technical interview process typically includes:

• Technical evaluation – Assessing coding skills, problem-solving abilities, and engineering fundamentals.
• Cultural fit assessment – Understanding how well a candidate aligns with your company’s values and work style.
• Communication skills assessment – Ensuring candidates can effectively express their ideas, which is critical in remote work environments.

There are several ways to evaluate a candidate’s technical skills, each with its own trade-offs. The most commonly used formats include:

1. Take-Home Assignments

Take-home assignments have become a popular choice for startups in recent years. They involve giving candidates a coding challenge to complete on their own time, usually within a few days.

Pros:

• Allows candidates to work in their own environment without the stress of a live interview.
• Gives insight into their ability to write clean, maintainable code.
• Enables candidates to showcase creativity and problem-solving skills.

Cons:

• Time-consuming for candidates, leading to lower completion rates.
• Difficult to ensure the work was done independently, especially with AI-assisted coding tools.
• Evaluation can be subjective and require significant effort from interviewers.

With the rise of AI tools like ChatGPT and GitHub Copilot, take-home assignments have become even easier to complete without demonstrating real engineering depth. This has led many companies to reconsider their effectiveness.

2. Live Coding Interviews

Live coding interviews involve solving a problem in real-time, usually via a collaborative coding environment like CoderPad or a shared Google Doc.

Pros:

• Provides real-time insight into a candidate’s thought process and problem-solving ability.
• Helps evaluate communication skills and how they handle ambiguity.
• Harder to fake skills compared to take-home tests.

Cons:

• Can be stressful for candidates, especially those unfamiliar with the format.
• Not a common practice in all regions (e.g., Latin America), putting some candidates at a disadvantage.
• Requires skilled interviewers to ensure fair and effective evaluation.

Despite these challenges, we at Silver.dev believe live coding interviews are the best way to assess a candidate’s true engineering capabilities. Seeing how someone approaches a problem, writes code, and communicates their thought process is invaluable.

3. Work Sample Tests

Work sample tests simulate real job tasks by asking candidates to solve a problem similar to what they’d encounter in the role.

Pros:

• Closely aligned with real-world work.
• Can test job-specific skills beyond just coding (e.g., debugging, system design).
• Reduces reliance on theoretical algorithm problems that may not reflect day-to-day work.

Cons:

• Can be difficult to standardize across multiple candidates.
• Might require more time and effort from both candidates and interviewers.
• Some candidates may struggle without sufficient context on the company’s codebase.

The Challenge of Live Coding for LatAm Talent

One unique challenge we see when working with Latin American engineers is that live coding interviews are not a regional standard. Many developers who have worked at large companies like Nubank, Mercado Libre, or Rappi have never experienced a live coding test, which puts them at a disadvantage compared to US-based engineers.

Additionally, remote candidates often face the added pressure of coding in English, which may not be their native language. This creates an additional hurdle that companies must be aware of when evaluating international talent.

To mitigate these challenges, consider:

• Providing guidance in advance: Explain the format and expectations to help candidates prepare.
• Using structured problem sets: Ensure fairness by using standardized, well-designed problems.
• Allowing clarifications: Encourage candidates to ask questions during the interview.

Despite these challenges, we believe that live coding remains the most effective way to assess a candidate’s abilities. However, choosing the right problem is crucial to ensuring you evaluate candidates fairly and effectively.

How to Design the Right Interview Process for Your Startup

Designing an effective interview process depends on several factors:

1. Your Hiring Budget – Higher salaries often attract candidates with more experience in structured interview formats.
2. Your Internal Resources – Do you have senior engineers who can conduct technical interviews effectively?
3. The Type of Engineer You Need – Frontend, backend, or full-stack developers may require different interview approaches.
4. The Urgency of Your Hiring Needs – Lengthy interview processes may lead to losing top candidates.
5. The Candidate Experience – A well-structured, transparent process improves engagement and completion rates.

A Recommended Interview Framework for Startups

For startups looking to hire strong software engineers, we recommend the following structure:

1. Initial Screening – A 30-minute conversation to assess motivation, experience, and communication skills.
2. Live Coding Interview – A 45- to 60-minute session focused on problem-solving and coding ability.
3. Work Sample Test (Optional) – A short, real-world task to evaluate practical skills.
4. Technical Deep Dive – A discussion about past projects, architectural decisions, and debugging scenarios.
5. Cultural Fit Interview – Ensuring alignment with your company’s values and work environment.
6. Final Decision & Offer – Providing prompt feedback and making an offer if the candidate meets expectations.

Final Thoughts

Interviewing software engineers is both an art and a science. The right process will depend on your company’s needs, the type of talent you’re attracting, and the resources you have available for hiring. While take-home tests have been a go-to for many startups, the rise of AI has diminished their reliability. Live coding interviews, despite their challenges, remain the best way to evaluate a candidate’s real skills.
