Engineering recruiting firms live and die by the first phone screen. The median time-to-fill for nonexecutive roles sits at 39 days according to SHRM's 2026 benchmarking, and senior engineering roles run longer. Meanwhile, a 2025 tech recruiting benchmark report found recruiters juggling 20 or more concurrent requisitions average 45 days to hire, compared with 29 days for those managing 1 to 4. The math is brutal: your best recruiters spend hours dialing candidates who never answer, and every day of delay hands passive engineers to a competitor who called first. AI-powered calling and screening tools have become the practical fix. Some run structured outbound campaigns against your candidate lists. Others screen applicants the moment they apply and hand your recruiters a clean shortlist. We compared three solutions that genuinely handle recruitment and screening calls, looking at how each one qualifies candidates, what it costs, and where the trade-offs sit. One clear pattern emerged: managed services that run the campaigns for you beat software you have to staff and configure yourself, especially for small and mid-sized firms without a dedicated ops team.
#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume. Most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before launch. No per-seat charges and no platform bill. The first campaign review is free.
My AI Call Center takes a different approach than most tools in this category: it's a done-for-you managed service, not software you have to learn and staff. You buy campaigns that the team runs for you, each built around one clear goal and quoted in full before launch. For engineering recruiting firms, that means Recruitment & Screening campaigns can confirm candidate interest, work through role-specific screening questions, capture availability and expectations, and route hot candidates to your recruiters live or into your CRM. You don't build workflows, train an AI, or babysit call logs. The team handles it, and you get a named outcome report with disposition codes, per-call notes, and follow-up requests routed back to your team.
Pros
- Managed service model means no software learning curve, no configuration, and no per-seat fees
- Full campaign cost is known before you approve launch, and the per-minute rate never moves mid-campaign
- Compliance-forward: consent review, AI disclosure, opt-out handling, and state calling-window rules are built into the process
- Outcomes route back into the CRM and scheduling tools you already run
- Nothing launches until you approve the script, escalation path, and disclosure handling
Cons
- You're buying a service, so you give up some hands-on control compared with running campaigns yourself in a self-serve tool
- One clear goal per campaign means complex multi-objective screening may need to be split across campaigns
- Pricing beyond the 9¢ per-minute base requires a quote, so you can't self-serve a final number from the website
Best for: Engineering recruiting and staffing firms that want screening calls run for them against reviewed candidate lists, without buying another platform or hiring ops staff. Especially strong for firms of 1 to 200+ staff that care about consent records and TCPA compliance.
#2 NTRVSTA — Published figures vary by source: from $1,200/month for small businesses in one listing, $1,500/month in a staffing-agency comparison, and starting at $3,000/month in a tech talent acquisition guide. Contact for a current quote.
NTRVSTA is a real-time AI phone screening platform aimed at staffing and recruiting firms with meaningful candidate volume. According to its published materials, the platform conducts AI-driven phone screens 24/7, reports candidate completion rates above 95% (which the company contrasts with the 40-60% rates it cites for video interviews), and supports nine or more languages including Spanish. For engineering recruiting firms, the appeal is throughput: candidates get screened the moment they enter the pipeline, and recruiters spend their time on qualified shortlists instead of first-contact calls. Integration is a core part of the pitch. NTRVSTA advertises connections with more than 50 ATS platforms, including Bullhorn, Greenhouse, and Workday, so screening outcomes flow into the systems staffing teams already run. The company also lists SOC 2 Type II, GDPR, and EEOC compliance among its credentials, which matters for firms placing candidates in regulated industries. The trade-off is the operating model. This is software you run, not a service that runs campaigns for you, so you'll need someone on your team to configure screening scripts, monitor performance, and manage the integration. Pricing is also on the higher end for smaller firms, with published figures ranging from roughly $1,200 to $3,000 per month depending on the source and plan tier.
Pros
- Broad ATS integration coverage, including Bullhorn and Greenhouse that most staffing firms already use
- 24/7 screening means evening and weekend applicants aren't lost to delay
- Strong reported completion rates compared with video screening formats
- Documented compliance certifications for regulated placements
Cons
- Self-serve software model requires internal configuration and monitoring
- Pricing is a significant monthly commitment for small firms
- Published pricing varies widely between sources, so budgeting requires a sales conversation
- May be more platform than a small boutique firm needs
Best for: Mid-sized to large staffing firms and engineering recruiting teams with high candidate volume that want to own the screening workflow in-house and already run a mainstream ATS.
#3 Agni by Ravan.ai — Starting at ₹8,000/month. Contact for pricing on higher volumes.
Agni is a conversational AI calling agent built around the first candidate screen. According to its recruitment use-case page, the agent calls candidates, confirms interest, works through role-specific screening questions including knockout criteria, and captures structured data like notice period, expected compensation, preferred locations, and shift availability. Every call returns a transcript, recording, summary, sentiment score, and disposition through after-call webhooks, which is genuinely useful if your firm wants auditable screening records rather than recruiter scribbles. Qualified candidates route to your recruiting team via live transfer or a queued callback with the full screen attached. Agni's standout capability is language coverage: 30+ Indian languages, 100+ accents and dialects, and native Hinglish handling. For engineering recruiting firms hiring in India or running campus and volume hiring drives, that's a real differentiator. The platform supports outbound campaigns with contact lists, schedules, call windows, retries, and concurrency controls, and it discloses AI assistance as part of the script with consent logging and audit trails. The obvious limitation for US-based firms is geographic focus. The language stack, pricing in rupees starting at ₹8,000/month, and market benchmarks all center on the Indian market. If your candidate pool is primarily North American, the fit is weaker, though the structured-screening mechanics themselves are sound.
Pros
- Exceptional multilingual coverage for Indian candidate pools
- Structured, auditable screening outcomes delivered straight to your ATS or tracker
- Low per-contact cost compared with human telecallers (the company cites ₹12-25 per AI-resolved contact versus ₹85-150 for a human call)
- Live recruiter handoff with full context attached
Cons
- Language and pricing focus center on the Indian market, limiting fit for US and Canadian firms
- Direct ATS integrations are limited today (GoHighLevel and Cal.com), with most ATS connections running through webhooks
- Requires technical setup via APIs and webhooks to get full value
Best for: Engineering recruiting firms and staffing teams hiring in India, running campus drives or high-volume screening cycles where multilingual AI screening at low per-contact cost matters most.
The right choice depends on how much of the calling work you want to own. If your firm has an ops person who loves configuring ATS integrations and tuning screening scripts, NTRVSTA gives you a powerful platform to run yourself. If you're hiring engineering talent in India at volume, Agni's multilingual screening is hard to beat on cost. But if you're like most small and mid-sized engineering recruiting firms, you don't need another dashboard. You need screening calls to happen, done correctly, against lists you know are clean, with outcomes landing back in your CRM. That's what My AI Call Center is built for. The first campaign review is free, the full cost is quoted before you approve anything, and nothing launches until you sign off on the script and escalation path. You'll know exactly what the calls are supposed to accomplish before a single minute is billed. If screening calls are eating your recruiters' week, plan your first campaign and see what a structured, managed approach does to your time-to-shortlist.
Frequently asked questions
What makes My AI Call Center different from AI screening software like NTRVSTA?
The operating model. My AI Call Center is a managed service: you buy campaigns that the team runs for you, with the script, disclosure handling, and escalation path approved by you before launch. NTRVSTA is software you configure and operate in-house. If you don't have someone dedicated to running calling campaigns, the managed model removes that staffing burden entirely, and pricing starts at 9¢ per connected minute with no per-seat fees or platform bill.
How does My AI Call Center handle consent and compliance for recruitment calls?
Every campaign starts with a list and consent review. The team checks list source, consent records, and calling windows before launch, and lists without clear permission records are flagged and in most cases declined. AI-generated voices are treated as artificial voices under the TCPA, so prior express consent is required. Every call includes AI disclosure, recipients can ask for a human or opt out, keyword opt-outs (STOP and REVOKE) are honored immediately, and DNC requests carry across all campaigns into your DNC records. State-specific quiet hours and registration rules are also honored.
Can screening outcomes integrate with my existing ATS and CRM?
Yes. My AI Call Center routes outcomes, bookings, and follow-up requests back into the CRM and scheduling tools you already run. Hot candidates transfer to your team live or land in your CRM. Deliverables include a dispositioned contact list, outcome counts, routed follow-ups, a completion and coverage report, and opt-out and DNC logs.
How much do these solutions cost for a typical engineering recruiting firm?
My AI Call Center starts at 9¢ per connected minute, tiered by volume, with a one-time campaign setup fee and flat monthly management fee quoted before launch; the first campaign review is free. NTRVSTA's published pricing ranges from roughly $1,200 to $3,000 per month depending on the source and plan. Agni starts at ₹8,000/month. For comparison, contingency placement fees for engineering roles run 15-25% of first-year salary according to Dover's 2025 fee guide, so screening-call tooling is a small line item by contrast.
Which solution is best for high-volume campus or seasonal engineering hiring?
For volume hiring in India, Agni is purpose-built for it, with outbound campaigns supporting call windows, retries, and concurrency controls for campus cycles and walk-in drives, plus 30+ Indian languages. For North American volume screening you want run for you, My AI Call Center's managed campaigns handle structured multi-touch outreach against reviewed lists. NTRVSTA suits firms that want to run high-volume screening in-house through their own ATS.
Do candidates know they're talking to an AI?
With My AI Call Center, yes: AI disclosure is on every call, and recipients can ask if the call is AI-assisted, request a human, or opt out at any point. Agni similarly discloses AI assistance as part of its script with consent logging. This disclosure-first approach reflects how regulators treat AI-generated voices, and it's worth confirming with any vendor before you launch a campaign.
How fast can we get a screening campaign live with My AI Call Center?
The process runs through six steps: campaign review, list and consent review, connecting your systems, script and escalation approval, launch and monitoring, and outcome routing. Nothing launches until you approve the script, disclosure, and escalation path. Timing depends on your list readiness and consent documentation, which is exactly why the review happens first. Start with the free campaign review to scope the goal and get a full quote before anything is billed.
