On Tech Interviews

In 1971, the landmark Supreme Court case Griggs v. Duke Power Co. established a crucial principle: even without explicit discriminatory intent, hiring practices that disproportionately exclude certain groups based on arbitrary criteria are illegal. This principle remains relevant today, as the tech industry grapples with its own deeply embedded patterns of white supremacy, mirroring the issues raised in Griggs.

The tech industry's hiring practices, dominated by whiteboard coding challenges, complex algorithmic puzzles, and high-pressure problem-solving exercises, are often touted as measures of technical proficiency and intellectual agility. However, these practices unintentionally create a system that favors certain demographics while marginalizing others. These biases not only perpetuate a homogenous workforce but also risk creating products and services that further marginalize the communities they serve.

Code of Exclusion

These seemingly neutral assessments often act as a filter, disproportionately excluding candidates from underrepresented groups. Whiteboard coding challenges, for example, place a premium on quick problem-solving under pressure, a skill that can be influenced by factors like access to quality education and cultural backgrounds that prioritize rote memorization over critical thinking. This creates a scenario where candidates with exceptional abilities but who are unfamiliar with the "coding interview" format are systematically disadvantaged.

Furthermore, the focus on abstract puzzles and algorithmic challenges often overlooks the practical skills and real-world experience crucial for successful software development. This creates a disconnect between the technical skills assessed during the interview process and the actual requirements of the job, further reinforcing the exclusion of diverse talent.

A Threat to Business and Society

The lack of diversity in the tech workforce has profound consequences, not only for the industry but also for society as a whole. It fosters a homogenous echo chamber, stifling the influx of fresh ideas and perspectives that are essential for innovation.

Blind Spots and Biased Products

A lack of diverse perspectives results in products and services that fail to meet the needs of a diverse user base. This is evident in the numerous instances where tech products have perpetuated harmful biases. For example, image recognition algorithms misidentified black people as gorillas, demonstrating the dangers of a homogenous workforce developing technology without considering the nuances of diverse human traits.

Reinforcing Systemic Inequalities

Tech companies are increasingly relied upon to power critical infrastructure, including healthcare, finance, and law enforcement. When these systems are built by homogenous teams, they are prone to perpetuating existing inequalities. For example, predictive policing algorithms, designed by predominantly white teams, have been shown to disproportionately target communities of color, leading to biased arrests and incarceration rates.

Lack of Innovation and Creativity

A homogenous workforce often lacks the diversity of thought and experience necessary to drive true innovation. Without the challenge of different perspectives, creativity can stagnate, leading to less innovative solutions and a decline in the competitive edge.

Limited Market Reach and Potential

A diverse user base demands diverse products and services. Companies that fail to understand the needs of diverse communities miss out on significant market opportunities and risk alienating a large segment of their potential customers.

Beyond the Whiteboard

The tech industry must move beyond the flawed metrics of whiteboard coding challenges and embrace more inclusive hiring practices. This requires a fundamental shift in perspective, recognizing that the current system unintentionally perpetuates inequality and prioritizing a more equitable approach.

The Path to Inclusion

Instead of requiring applicants to request accommodations, companies must proactively design accessible interview processes. This means:

1. Proper Interview Length. Interviews should be sufficiently long to allow applicants to fully process information and provide thoughtful responses. This ensures that candidates are not rushed or pressured, particularly those who may require additional time to process complex information.

2. Written Questions. Providing written questions prior to the interview empowers applicants to prepare their thoughts and responses, creating a more level playing field for individuals with diverse learning styles and communication preferences. This fosters a more inclusive environment where all candidates can showcase their skills and abilities.

3. Structured Environment. Every applicant should have a clear understanding of the interview process, its timeline, and its format. This transparency builds trust and reduces anxiety, creating a more comfortable and less stressful environment for all participants.

4. Focus on Practical Skills. Interviews should prioritize practical skills and real-world experience relevant to the job function. This ensures that the selection process is grounded in actual job requirements, rather than relying on abstract problem-solving abilities that may not accurately reflect the demands of the role.

5. Embrace Diversity. Hiring managers should actively seek out candidates with diverse backgrounds and experiences. This can be achieved by expanding recruitment efforts to include underrepresented groups, partnering with organizations promoting diversity in tech, and creating a welcoming environment that celebrates diversity.

6. Implement Blind Review. Blind review processes, which remove identifying information from resumes and applications, can help mitigate unconscious bias and promote a fairer evaluation of candidates.

7. Continuous Learning. The tech industry must prioritize continuous learning and development, ensuring that hiring practices are constantly reviewed and adjusted to address emerging challenges and create a more inclusive workforce.
