The Hidden Cost of Technical Interviews: Why Your Process is Leaking Talent

TLDR: Technical interviews for security roles often suffer from bloated, multi-stage processes that alienate top-tier talent and fail to accurately assess real-world skill. By focusing on high-friction assessments like take-home assignments, companies inadvertently filter for candidates with free time rather than those with deep expertise. Security leaders should streamline these pipelines to prioritize practical, relevant demonstrations of skill over generic coding tests.

Security hiring is broken. We spend years building red teams and refining our tradecraft, only to be subjected to interview processes that feel like a bad CTF from 2012. The industry has fallen into a trap where we conflate the ability to solve a generic algorithmic puzzle with the ability to find a zero-day or architect a secure cloud environment. This disconnect is not just annoying for candidates; it is a massive operational risk for companies that need actual security engineering talent, not just people who can memorize OWASP Top 10 definitions.

The Four Stages of Friction

Most security hiring pipelines follow a rigid, four-stage structure: the introduction, the technical assessment, the onsite interview, and the executive review. Each stage is a potential point of failure, but the technical assessment is where the most damage occurs.

Many organizations rely on LeetCode or similar platforms to test candidates. This is a mistake. A security engineer’s value is rarely found in their ability to invert a binary tree in O(n) time. It is found in their ability to understand how a specific authentication bypass works or how to chain vulnerabilities in a complex microservices architecture. When you force a senior researcher to spend a week on a take-home assessment, you are not testing their skill. You are testing their willingness to jump through hoops. The best people in this industry are busy. They are hunting bugs, running engagements, or building tools. They do not have time for your three-week, five-round interview marathon.

Why Your Technical Assessment is Failing

The obsession with "coders who can do security" has created a false dichotomy. We see companies asking detection engineers to pass the same coding bars as backend developers. This ignores the reality of the role. A great detection engineer needs to understand how to query logs, identify anomalous traffic patterns, and write effective detection logic. They do not need to be experts in dynamic programming.

When you use a generic take-home assessment, you lose the ability to see how a candidate thinks. A better approach is to ask for a portfolio. If a candidate has a GitHub profile with active projects, or if they have published research or bug bounty write-ups, that is your assessment. It is real, it is verifiable, and it demonstrates a passion for the craft that no multiple-choice test can capture. If you must use a test, make it relevant. Give them a sanitized log file and ask them to find the indicator of compromise. Give them a snippet of vulnerable code and ask them to explain the exploit chain.

The Cost of Being a Gatekeeper

Rejection trends in the security industry are often driven by ego rather than merit. I have seen candidates with stellar backgrounds rejected because they were not "curious enough" or because they were "too argumentative." In our field, being argumentative is often a synonym for "I know this is broken and I am trying to tell you why." If a candidate challenges your assumptions during an interview, that is not a red flag. That is a demonstration of the exact critical thinking skills you are trying to hire.

Furthermore, the "culture fit" excuse is frequently used to mask bias. We need to stop looking for people who think exactly like the existing team. We need people who bring different perspectives, different toolsets, and different experiences. If your team is entirely composed of people who came from the same three universities and the same two companies, you have a blind spot. Your interview process is likely reinforcing that homogeneity.

Practical Steps for Better Hiring

If you are a founder or a hiring manager, you need to audit your pipeline today. Start by asking your team to take the same technical assessment you give to candidates. If they find it tedious, irrelevant, or overly long, your candidates will too.

Focus on these three areas:

1. Respect the candidate's time. If you have a multi-stage process, ensure each stage provides value to both sides.
2. Prioritize real-world artifacts. Look at their CVE contributions, their blog posts, or their open-source tools.
3. Standardize the evaluation. Use a rubric to ensure you are measuring skills, not personality.

The best security talent is not looking for a job where they have to prove they can solve a puzzle. They are looking for a job where they can solve problems. If your interview process does not reflect that, you will continue to lose the best people to companies that do. Stop treating your hiring pipeline like a security barrier that needs to be as difficult as possible to bypass. Treat it like a product. If the user experience is bad, your users will go elsewhere.
