Abstract

The Indian tech hiring market filters heavily on college pedigree. “IIT/NIT only” policies — explicit or implicit — exclude over 99% of engineering graduates before any evaluation of actual capability. This paper examines the evidence on what pedigree actually predicts, quantifies the cost of pedigree-based filtering, and presents data from LayersRank deployments showing how capability-based assessment identifies strong talent that pedigree filtering misses.

Executive Summary

Key Findings

01

IIT/NIT graduates represent less than 1% of Indian engineering talent.

Filtering to this pool excludes 99%+ of candidates before any evaluation.

02

Pedigree correlates with job performance, but weakly.

The correlation fades significantly after 2–3 years of work experience. For experienced hires, college brand has minimal predictive value.

03

Pedigree filtering has significant hidden costs.

Higher salary expectations, reduced diversity, smaller talent pools, and missed hires from non-target schools.

04

Capability-based assessment identifies strong non-pedigree talent.

In LayersRank deployments, 30–40% of top-scoring candidates come from colleges that would fail traditional pedigree filters.

05

Companies can maintain quality standards while expanding pools.

The bar doesn’t need to lower — it needs to measure the right things.

Recommendations

Remove or de-emphasize college filters in first-round screening

Evaluate all candidates on demonstrated capability

Use structured assessment to ensure consistent standards

Track outcomes by college tier to validate approach

The Pedigree Landscape in India

2.1 The Numbers

India produces approximately 1.5 million engineering graduates annually from:

TierInstitutionsCountAnnual Grads% Total
Tier 1IITs23~16,0001.1%
Tier 1NITs31~20,0001.3%
Tier 1BITS, IIIT, top private~20~15,0001.0%
Tier 2State colleges, mid-private~500~200,00013.3%
Tier 3Regional colleges~3,000+~1,250,00083.3%

Total Tier 1: ~51,000 graduates (3.4%)

Non-Tier-1: ~1,450,000 (96.6%)

When companies filter to “IIT/NIT only,” they’re choosing from 2.4% of the talent pool.

2.2 How Pedigree Filtering Works

Pedigree filtering operates at multiple stages:

Explicit filtering

ATS rules that reject applications from non-target colleges. Job postings that specify “IIT/NIT preferred.”

Implicit filtering

Recruiters sorting resumes by college first. Interview panels unconsciously favoring candidates from familiar schools.

Network effects

Referral programs that over-represent current employee demographics. Campus recruiting that only visits target schools.

Resume ordering

Candidates from target schools getting more attention, faster responses, and benefit of the doubt in marginal cases.

2.3 Why Companies Filter on Pedigree

Efficiency

Reviewing 100,000 applications is impossible. College acts as a pre-filter.

Quality

IIT admission is competitive. Competitive admission predicts capability.

Risk

We know IIT graduates. They’re a known quantity.

Network

Our IIT employees refer other IIT candidates. The network is self-reinforcing.

Each argument has validity — and significant flaws, which we examine in Section 3.

What Pedigree Actually Predicts

3.1 The Research on College and Job Performance

Meta-analyses of education credentials and job performance show:

Education level → job performance

Schmidt & Hunter, 1998

r = 0.10

College grades → job performance

Roth et al., 1996

r = 0.16

College prestige → job performance

various studies

r = 0.09–0.12

For context:

0.09–0.12

College prestige

~1% of variance explained

0.38–0.51

Structured interviews

Industry standard

0.54

Work sample tests

Best single predictor

College prestige is among the weakest predictors of job performance that companies commonly use.

3.2 What IIT Admission Actually Measures

JEE measures

  • Performance on physics, chemistry, mathematics problems
  • Timed problem-solving under pressure
  • Pattern recognition and analytical reasoning
  • Recall of concepts taught in coaching programs

JEE does NOT measure

  • Communication skills
  • Collaboration ability
  • Learning velocity in novel domains
  • Persistence on ambiguous problems
  • Domain expertise (acquired after college)
  • Work ethic and professionalism

3.3 The Fading Pedigree Effect

The predictive value of college pedigree decreases with experience:

Experience LevelPredictive Value
Campus hire (0 years)
Moderate
1–2 years
Low-Moderate
3–5 years
Low
5+ years
Minimal

After 3–5 years of work experience, actual job performance, skills acquired, and demonstrated results dwarf any signal from college brand. For experienced hiring, pedigree filtering makes almost no sense from a predictive standpoint.

3.4 What Pedigree Actually Proxies

When college pedigree does correlate with outcomes, it often proxies other factors:

Socioeconomic status

JEE coaching costs ₹2–5 lakh. Students from wealthy families have access; others don’t. “IIT caliber” partly means “could afford coaching.”

Urban advantage

Coaching centers concentrate in metro areas. Rural students face structural disadvantage regardless of raw ability.

Family education

First-generation college students are underrepresented at IITs. Parental education provides advantages unrelated to candidate ability.

Early decision-making

The choice to pursue IIT happens at age 14–15. Many talented people made different choices as teenagers.

Filtering on IIT partly filters on wealth, geography, and family background — not just capability.

The Cost of Pedigree Filtering

4.1 Direct Costs

Salary premium

IIT graduates command 20–40% higher salaries than equivalent non-IIT candidates. For a team of 50, this costs ₹50–100 lakh annually.

Smaller talent pool

Competition for 50,000 Tier-1 graduates is intense. Every company wants the same candidates. You pay more and get fewer.

Longer time-to-fill

Restrictive filters extend searches. Positions stay open longer. Opportunity cost accumulates.

Reduced offer acceptance

Top IIT candidates have many offers. Your acceptance rate may be 40–50%. You must interview more candidates to fill each role.

4.2 Indirect Costs

  • Missed hires. Strong candidates from non-target schools are never evaluated. You don’t know what you’re missing, but you’re missing it.
  • Reduced diversity. Pedigree filtering correlates with socioeconomic, geographic, and caste demographics. Homogeneous teams have blind spots.
  • Monoculture risk. Teams from similar backgrounds think similarly. Diverse perspectives reduce groupthink.
  • Employer brand limitation. “IIT only” reputation limits your appeal to 96% of candidates who might otherwise be interested.
  • 4.3 The Opportunity Cost Calculation

    Consider a company that needs 100 engineers:

    Pedigree Approach

    Applications (Tier-1)500
    Interviews100
    Offers50
    Acceptances30

    Need to repeat cycle or compromise

    Capability Approach

    Applications (all tiers)2,000
    Assessments (automated)200
    Interviews (top scorers)100
    Offers → Acceptances60 → 50

    Roles filled faster, at lower cost

    5

    Alternative Approaches

    5.1 Capability-Based Hiring

    Instead of filtering on credentials, evaluate demonstrated capability:

    What to measure

    • Technical skills relevant to the role
    • Problem-solving approach
    • Communication clarity
    • Learning orientation
    • Collaboration patterns

    How to measure

    • Structured assessments with consistent criteria
    • Work samples or simulations
    • Behavioral interviews with defined rubrics
    • Reference checks focused on relevant competencies

    5.2 Blinding and Anonymization

    Remove pedigree signals from evaluation:

    Strip college names from resumes during review
    Evaluate responses without demographic information
    Score assessments before revealing background

    This forces evaluation on substance rather than credential.

    5.3 Outcome Tracking

    Track performance ratings by college tier
    Compare retention rates across demographics
    Analyze time-to-productivity by background
    Iterate based on actual outcomes

    If Tier-2 hires perform comparably to Tier-1 hires, expand Tier-2 sourcing.

    LayersRank Data: Beyond Pedigree

    6.1 Methodology

    12,847

    Candidate assessments

    identity-blind evaluation

    23

    Companies

    using LayersRank

    1,247

    Post-hire tracked

    6+ months performance data

    6.2 Assessment Scores by College Tier

    Distribution of LayersRank scores by college tier:

    College TierMean ScoreStd DevTop 20% Rate
    Tier 1 (IIT/NIT/BITS)72.414.228%
    Tier 2 (State/Mid-Private)64.816.118%
    Tier 3 (Regional)58.317.812%

    Interpretation

    Tier-1 candidates score higher on average, but the distributions overlap substantially. 18% of Tier-2 and 12% of Tier-3 candidates score in the top 20% overall — these are candidates who would be filtered out by pedigree but are genuinely strong.

    6.3 High Scorers by College Tier

    Where do top-20% candidates come from?

    Source% of Top 20%% of Pool
    Tier 142%31%
    Tier 238%42%
    Tier 320%27%

    Key Finding

    58% of top-scoring candidates come from Tier-2 and Tier-3 colleges.

    If you filter to Tier-1 only, you miss more than half of your strongest candidates.

    6.4 Post-Hire Performance Correlation

    For candidates with 6+ months of performance data (n=1,247):

    MetricLayersRank ScoreCollege Tier
    Manager rating (1–5)r = 0.42r = 0.11
    Promotion within 18 monthsr = 0.38r = 0.08
    Retention at 12 monthsr = 0.29r = 0.05

    LayersRank assessment scores predict job performance 3–4x better than college tier.

    6.5 Case Example: GCC Engineering Team

    A Fortune 500 GCC shifted from pedigree-based to capability-based hiring:

    Before (Tier-1 only)

    Candidates reviewed200 (all Tier-1)
    Hired50
    12-month performance3.2 avg rating
    Tier-1 composition100%

    After (All tiers, LayersRank)

    Candidates assessed800 (all tiers)
    Hired50 (top scorers)
    12-month performance3.4 avg rating
    Tier-1 composition58%

    Performance improved slightly while expanding the talent pool 4x and reducing salary costs by ~15% (lower Tier-1 premium).

    Implementation Recommendations

    7.1 For Campus Hiring

    Remove Tier-1 only filters. Assess all applicants from all colleges with consistent criteria.
    Use structured assessment. Evaluate technical, behavioral, and contextual dimensions with defined rubrics.
    Track outcomes by tier. After 6–12 months, compare performance across college tiers. Use data to calibrate.
    Expand campus visits. Add strong Tier-2 colleges to your campus recruiting circuit.

    7.2 For Experienced Hiring

    De-emphasize education entirely. For candidates with 3+ years of experience, college should have minimal weight.
    Focus on recent performance. Work history, accomplishments, and demonstrated skills matter more than credentials.
    Use work samples. Evaluate actual capability through simulations, take-homes, or structured technical discussions.

    7.3 For Organizational Change

    Start with a pilot

    Run capability-based assessment alongside traditional process. Compare outcomes.

    Build data

    Track which assessment approach produces better hires. Let data drive decisions.

    Communicate the change

    Help hiring managers understand that capability-based assessment maintains (or improves) quality while expanding access.

    Set targets

    Consider diversity targets for college tier representation. Hold teams accountable.

    7.4 For Individual Hiring Managers

    Check your assumptions. Do you believe Tier-1 candidates are better? What’s that belief based on?
    Audit your decisions. Look at your last 20 hires. What percentage were Tier-1? How did they perform?
    Try blinding. Evaluate candidate responses without seeing resumes first. Does your assessment change?

    Conclusion

    Pedigree filtering is the default in Indian tech hiring. It’s comfortable, defensible, and wrong.

    The evidence is clear:

    01

    College prestige weakly predicts job performance

    The correlation is among the lowest of any commonly used hiring signal.

    02

    Pedigree filtering excludes most of the talent pool

    96.6% of engineering graduates never get evaluated.

    03

    Strong candidates exist across all college tiers

    58% of top scorers come from Tier-2 and Tier-3 colleges.

    04

    Capability-based assessment identifies them

    LayersRank scores predict performance 3–4x better than college tier.

    The question is not “Should we lower our bar for non-Tier-1 candidates?”

    The right question:

    “Should we measure the right things for all candidates?”

    Same bar. Better measurement. Wider pool.

    Companies that make this shift gain access to talent their competitors ignore. They build more diverse teams. They often reduce costs while maintaining or improving quality.

    The pedigree premium is a tax you don’t have to pay.
