Why custom builds take six months - and yours does not have to
Building an assessment from scratch is slow for structural reasons: someone has to design the scenarios, the flow and adaptability, define the scoring, build it, test it, and fix what breaks. Done in-house or with a traditional vendor, that easily takes six months of effort.
The faster route does not come from cutting corners. It comes from starting with scenarios that already work and shaping them to your role.
From brief to live assessment in 14 days
In our engagements we have seen exactly how fast this can move. A consulting firm needed a tailored market-sizing assessment for its campus season; its previous first round - manual case interviews - was consuming 60+ partner hours per cycle and producing scores no two interviewers agreed on. Working from our consulting template, the assessment was designed, scored and branded in 14 days, and the firm moved first-round evaluation into it.
The first cycle delivered:
- A 72% reduction in early interview volume
- 110+ partner and recruiter hours returned to the team
- 80% of finalists rated as strong matches by hiring managers, up from 52% under the previous process
The assessment paid for itself before the season ended. And 14 days is not the floor - where the calendar demanded it, we have configured a custom market-sizing build in 10 days of focused iteration and gone live immediately.
How we collapse the timeline
You are not commissioning a scenario from nothing. The build begins with one of 15+ proven tested, refined across hundreds of live cohorts, and changes only what needs to change. In practice the loop looks like this: your hiring manager sits with one of our specialists and points at a decision stage - "the real version of this involves the client changing the brief halfway through." The specialist rewrites the stage so the brief shifts mid-task. The manager adds: "score how they handle the change, not just the final number." The rubric is adjusted on the spot.
That division of labour is the whole method. You provide the institutional knowledge; we provide the design expertise and manage the configuration. Building and deploying your real-work simulation requires only a few collaborative meetings and content reviews from your side - most bespoke scenarios go from first conversation to launch in under four weeks, including design, iteration and calibration, and template-led builds go faster. What the underlying engine does with it all - branching scenarios, adaptive difficulty, live scoring - is on our how our simulations work page.
Speed does not sacrifice precision
The platform's modular architecture allows fine-tuning at every level: decision points, scoring rubrics, even language adjusted to fit your culture. And unlike a fixed test, the assessment sharpens with use - after the first cohort you see exactly where strong candidates pulled away and where a task failed to separate anyone, and those points get tuned before the next run. Need to adjust for a new role or a new skill next year? The simulation is modified or expanded without starting from scratch, so it stays relevant as your needs evolve.
What it measures is worth the tuning. Decades of selection research show that watching someone do a version of the actual job is among the strongest predictors of performance there is - far ahead of anything a CV or a generic test can offer. A scenario built from your real workflows sits as close to the job as an assessment can get, and you move it closer every cycle.
What the investment returns
The payback shows up in three places, quickly.
- Time. Less time filtering unqualified applicants, fewer resources spent on repetitive early interviews, and a shortlist your team can act on immediately.
- Trust. Hiring managers see their real work scenarios brought to life in the vetting process. That builds confidence in the shortlist and creates a shared view of what good looks like - in our engagements, 90% of hiring managers say they prefer simulation-generated shortlists, which means fewer decisions overridden by gut feel.
- Avoided mistakes. A failed hire costs at minimum 30% of first-year salary (US Department of Labor). An assessment that sharpens who reaches the offer stage typically covers its cost by preventing a single wrong hire - which is why companies commonly reach positive ROI within one hiring cycle, and 3-5x over the first year once quality improvements and recruiter time are counted.
If you need volume before precision, a branded campus recruitment campaign attracts and screens thousands of students in your name - and if you want to skip the event entirely, the pre-screened talent pool holds 100,000+ candidates already assessed.
