TCS Hiring Process: Where Hyring's AI Agents Fit

TCS closed Q3 FY25 with approximately 607,354 employees and a target of onboarding 40,000+ fresh graduates in FY25 alone, with plans to push past 42,000 in FY26. Over 300,000 candidates register for the TCS National Qualifier Test (NQT) each cycle.

This blueprint maps where Hyring's AI agents can absorb manual workload across that recruitment funnel, what outputs they produce for hiring teams, and which KPIs keep the model measurable.

Hyring Funnel

This article is a planning framework showing where AI can reduce manual effort across the funnel.

The Map

You know that a hiring model is real if the individuals in charge can point to a figure that changed last week. If they cannot, it is a strategy document gathering dust.

This blueprint was developed for the TCS hiring process, which operates at 300,000+ application volumes per NQT cycle. It has four parts:

  • A funnel map shaped around TCS's high-volume campus workflow.
  • A phased deployment plan with weekly milestones.
  • A KPI scoreboard carrying risk indicators for each metric.
  • An ROI module with adjustable inputs and a clear disclaimer on projections.

TCS runs the NQT across hundreds of engineering colleges and open registration channels. Candidates first progress through an aptitude and cognitive test, technical assessment, and then managerial and HR interview rounds, all on compressed timelines that overlap with competing campus drives from Infosys, Wipro, HCLTech, and Cognizant - a real binder!

The friction stacks heaviest in the first three stages of that funnel. Those stages are repetitive, rubric-driven, and scored. That makes it an automatic case for automation without touching evaluative judgment.

Current  State

TCS closed Q3 FY25 with approximately 607,354 employees as of December 31, 2024, per its quarterly earnings release. That figure represented a net decline of 5,370 from Q2 FY25. Trailing twelve-month IT services attrition stood at 13%, well below the 21.5% peak reached in Q2 FY23 but still generating replacement hiring demand on top of growth-driven intake.

Campus onboarding has a narrative of correction and recovery. In the post-pandemic hiring spree, TCS campus onboarding saw around 78,000 freshers get on-boarded in FY22. This was followed by a reduction to around 44,000 in FY23 as bench sizes swelled and deal ramps slowed down. FY24 was the first year in the last 19 years in which the company reported a net headcount reduction of 13,249 employees, ending the year with 601,546 employees. The management kept the fresher intake target at around 40,000 for FY24 and FY25 as well.

The CHRO indicated in a December 2024 Economic Times interview that FY26 fresher intake would rise above 42,000, driven by AI and GenAI project demand.

The application-to-offer math is stark. TCS NQT registrations exceed 300,000 annually, with a certified talent pool of over 600,000 candidates according to TCS iON.

For every campus position filled, TCS processes roughly eight to ten applications. A single NQT cycle targeting 20,000 hires can pull in 160,000 to 200,000 active test-takers. That volume hits the recruiter team's first-stage capacity all at once.

Problems In The TCS Hiring Process

While 200,000 candidates are trying to take the NQT in one window, a two-day delay in the shortlisting phase results in a week-long delay before any human interaction takes place. A week, in which Infosys, Wipro, HCLTech, Cognizant, and countless product startups are vying for the same talent pool, is enough to lose a fifth of your shortlisted talent to other job offers - which in the fast-paced world of tech innovation is bordering on criminal.

NQT result processing creates a single-threaded bottleneck at scale

The NQT produces scored results for 200,000+ candidates in just days. But to produce role-specific shortlists from these scores, such as TCS Ninja or TCS Digital roles, recruiters need to correlate these scores with their respective thresholds, validate candidate eligibility, and then prepare these candidates for the next phase of evaluation. At 8 minutes per candidate to review their resumes and scores, 200,000 candidates translate to 26,600 person-hours of work. However, most of this work is concentrated in just 2 weeks, which implies either we scale for this duration or we increase the candidate queue every day.
After shortlisting the candidates, phone or video screens are conducted to test the candidates' communication skills, interest in the role, and availability. This takes around 15 to 20 minutes for each candidate. This phase is attended by an estimated 50,000 candidates in a major hiring cycle. This is equivalent to around 12,500 to 16,600 person-hours of conversations following the same format every time. The questions don't change. The scoring criteria don't change. Only the candidates change.
TCS sells engineering talent to their clients. A lead developer pulled in for campus interview sprints for 4 hours a day is 4 hours of unbilled delivery time. At their scale, if 20,000 candidates make it to the technical panels and each interview takes 35 minutes with 1.5 panelists on average, it adds up to 17,500 person hours of cost, but it does not show up in the recruitment budget anywhere. It shows up in the project margins, which may not be noticed until the delivery manager brings it up.
For campus hires, they usually have two to four offers by the final semester. The TCS interview process is as much about speed as it is about brand name. A candidate who has cleared the NQT on Monday and has not received an interview invitation by Thursday is actively being processed through other firms as well. The dropout is not tracked because they simply stop responding and do not decline the offers.
As of 2020, an increasing percentage of TCS's screening rounds are conducted via video. Identifying tab switching, secondary speakers, and identity substitution in a live conversation is based on the interviewer's ability to pick up on peripheral cues. After the sixth interview of the day, this ability is diminished and full-on biases creep in. The lack of integrity monitoring in scalable remote interviews leaves a blind spot, and it grows with scale.

KPI Scoreboard — TCS Hiring Model

Time to Screen

Definition: Elapsed time from NQT result to L1 screening decision.

Risk indicator: Getting below 48 hours is the target. If panel-stage rejection spikes after you compress this, the early filter may have swapped speed for accuracy.

Screening Throughput

Definition: Initial screen volume completed per recruiter per week.

Risk indicator: If throughput climbs but the next-stage advance rate drops, the intake criteria are too loose. Tighten them before scaling volume.

Interview Completion Rate

Definition: Percentage of candidates who receive an interview invite and finish the full evaluation.

Risk indicator: Below 60-70% completion usually points to unclear invite instructions, broken access links, or assessment length past 45 minutes.

Early Stage Drop-offs

Definition: The specific funnel step where candidates withdraw from participation.

Risk indicator: Heavy drop-off at the assessment stage (not the scheduling stage) often means the test feels too long or too hard relative to role level. Freshers abandon faster than lateral hires.

Panel Hours per Hire

Definition: Total human interviewer hours consumed per finalised hire.

Risk indicator: Track alongside 3-month retention. If panel hours drop and retention also drops, the AI filter may be pruning soft-skill signals that panels would have caught.

Pass-through Rate

Definition: Percentage of candidates advancing from one stage to the next.

Risk indicator: A 20-point variance between two campuses recruiting for the same role means the rubric needs campus-level calibration, not a single uniform threshold.

Shortlist-to-Offer Ratio

Definition: Shortlisted candidates needed to produce one accepted offer.

Risk indicator: Moving from 8:1 to 4:1 is solid. Moving from 8:1 to 3:2 means you are pruning viable candidates who would have performed.

Integrity Flag Rate

Definition: Percentage of AI interviews triggering fraud or cheating alerts.

Risk indicator: A baseline of around 5% is normal. A jump above 10% from a specific college or region needs a manual review before drawing quality conclusions about that source.

Time to First Touch

Definition: Lag between NQT completion and first outreach to the candidate.

Risk indicator: A fast first touch followed by silence for a week creates worse candidate perception than a consistently moderate pace. Touching base at two and three matter as much as touching base at one.

SLA Adherence

Definition: Percentage of candidates receiving status updates within X days.

Risk indicator: When this slips, offer acceptance rates fall within the same week. Slow updates lose candidates to faster-moving competitors.

Hours Saved Annually

Three stages account for the majority of manual effort in the TCS recruitment process — NQT result screening, L1 phone or video screens, and early technical panels. This is where the time is spent and how we will recover it.

  • Resume and NQT score screening: 300,000 candidates, average review time 8 minutes per candidate, total time 40,000 person-hours. Using AI resume screening, we can reduce this to approximately 4,000 person-hours of recruiter review on AI-generated shortlists.
  • L1 phone and video screens: 50,000 candidates remaining after shortlisting, 20 minutes per candidate, total 16,600 person-hours. AI phone and video agents completing these screens leave approximately 2,000 person-hours of recruiter review time.
  • Early technical panels: 20,000 candidates remaining after L1, 35 minutes per candidate, 1.5 panelists average, total 17,500 person-hours. AI coding and video screening reduces the number reaching human panels by 55%, saving approximately 9,600 person-hours.

Total estimated hours recovered annually: ~58,000.

Current State Costing vs. Target State with AI

At an 8:1 application-to-hire ratio, every efficiency gain at the funnel top reduces cost at every stage below it.

MetricCurrent manual processTarget with Hyring AI agents
L1 screening cost~$2.1M (recruiter hours at $16/hr loaded, coordinator time, telephony)~$210K (at ~$1 per AI-conducted screen, plus ~$50K in recruiter review hours)
Engineering panel loadHeavy: engineers conduct early technical screens across campuses, averaging 4–5 interviews per day during peak sprintsLight: panels receive only candidates who cleared AI resume, phone, and coding gates. Interview load drops to 2 per day with higher relevance
Interview scalabilityCapped by interviewer calendars, timezone coordination, and NQT cycle compressionConcurrent and asynchronous: candidates complete AI assessments on their own schedule within a defined window

Funnel completion rate~25% of candidates who enter the shortlist stage reach the offer stage (estimated from industry benchmarks for large IT services)>68% projected, driven by reduced wait times, self-scheduling, and faster status communication

Where the $3.8M+ Savings Come From

The largest cost recovery does not sit in recruitment. It sits in engineering delivery margins and candidate acquisition overhead.

  • L1 volume handled by AI Agents: At 300,000 registrations and a 20-minute average screen for those reaching L1, the manual screening stage costs roughly $2.1M in loaded recruiter time. AI phone and video agents conducting 90% of those screens at ~$1 each bring the figure to approximately $260K. Net recovery: ~$1.8M.
  • Engineering hours returned to client delivery: TCS charges engineers based on practice and region, and the internal loaded cost for mid-level developers in India is typically in the range of $30 to $50/hour. Making up 9,600 panel hours at a midpoint of $40/hr is approximately $384K of delivery capacity restored.
  • Scheduling and coordination overhead cut: NQT cycle coordination, which includes slot management, candidate communication, rescheduling loops, and no-show follow-ups, consumes an estimated 12,000 to 15,000 coordinator hours per year at this scale for TCS. Self-scheduling through AI assessment links eliminates approximately 60% of this process. Estimated recovery: ~$190K.
  • Re-screening and integrity investigation costs mitigated: Manual fraud detection identifies problems too late, after a candidate has cleared two rounds of evaluation. Too many disqualifications occur too late in the process, causing all prior evaluation time to be for naught. Automating the first stage of the AI interview process for proctoring can save $120K in wasted evaluation time annually.

Total estimated annual savings: ~$3.8M (rounded conservatively, includes secondary effects across multiple NQT cycles and lateral hiring).

Cumulative Savings vs Cost

The savings build up over each NQT cycle and hiring sprint. In this scenario, the break-even is achieved in month five. This timeframe can be compressed even further if the lateral hiring volume is added to the same Hyring deployment, as the marginal cost per additional AI interview is nearly zero.

What makes the TCS hiring process uniquely suitable for AI deployment is the type of first three stages of the hiring funnel that NQT drives.

These are not stages that require creative evaluation and relationship-based judgments.

TCS Hiring Process Implementation

A rollout attempt to accommodate 300,000 NQT registrations on day one will fail. Phased rollout maintains existing workflows, creates comparison data, and provides hiring panels with time to trust AI outputs before relying on them.

Week 1: Select pilot roles and lock evaluation criteria

Select two different roles with different scoring rubrics. TCS Ninja Software Developer and TCS Digital Data Analyst are good choices as they have different NQT score thresholds and interview rubrics.

Clearly determine the thresholds for passing and failing. Decide upon the exact handover point for AI results and human review. Obtain written agreement from the leaders of the hiring panels before entering the first candidate into the system.

Activate the AI Phone Screener and AI Video Interviewer for the pilot roles only. Run them in parallel with your existing manual process for the first 72 hours.

Compare Outputs — score distributions, time-to-decision, and candidate completion rates. Track these on a daily basis. Discrepancies in recommendations from AI systems and decisions from human evaluators can be identified in real-time, enabling rubric calibration before scale.

Add AI Coding Interviewer as an option under the engineering track. Add the English Proficiency Test as an option for any role where English proficiency is a first-year course requirement. Start monitoring integrity flag rates.

Compare this to whatever level of fraud detection you're doing manually, even if this is a gut check, and note spikes in flag rates coming from specific colleges — this is not necessarily a reason to reject candidates, but a threshold check.

Key review questions: Did pass-through rates improve without panel satisfaction declining? Did candidate NPS hold steady or improve? Did time-to-offer compress measurably?

Adjust question banks, scoring weights, and flag sensitivity based on the data. Expand to the next batch of requisitions only after two consecutive review cycles show stable SLAs.

Frequently  Asked  Questions

Each candidate in a batch receives their assessment link at the same time. Thousands of phone and video sessions are handled at the same time by Hyring's AI agents, so a 200,000-candidate NQT process takes just a few days to clear L1, as opposed to the three to four weeks a human assessment team might take.

A report with the breakdown of the competency score, the summary of the responses, the areas that need to be probed further, and the advance or hold recommendation. This saves the recruiter's time as they can go through the report in just 90 seconds, as opposed to taking a 20-minute call.

The AI video interviewer monitors six signals in parallel — tab switches, secondary faces, voice mismatches, gaze anomalies, lip sync gaps, and clipboard pastes. These are combined to produce a composite integrity score. No single flag is used to reject videos automatically — we see which flags were triggered and make decisions accordingly.

Candidates pick their own assessment window, skip scheduling back-and-forth, and receive status updates faster because scoring happens immediately after completion. Feedback from platforms using this model indicates candidate satisfaction holds steady or improves relative to traditional phone screens.

Yes. The AI Coding Interviewer supports Java, Python, C++, JavaScript, SQL, and other environments with configurable difficulty per role. A TCS Ninja backend developer and a TCS Digital data engineer see entirely different assessments without separate platform instances.

Panels only come in at the very end, at the final stage. That's because, by then, the candidate has already passed the resume screening, phone/video, coding, and language tests. The engineers use the interview time to assess problem-solving depth and culture fit, not to re-check the candidate's basic qualifications.
