AI / ML product3D / GPU low-levelRequirement reframing

Case 1: when “CUDA required” was shrinking the funnel

The business challenge
A product ML/AI company had spent months unable to fill a rare hybrid role — 3D graphics plus low-level GPU development. The requirement read as “CUDA required” and sharply narrowed the funnel of strong candidates.
How we worked
On concrete CVs we showed the client that the task is solved by a broader competency — low-level GPU development (graphics and/or compute) — and that CUDA logically belongs in the “nice-to-have” column. We reframed the requirement into a workable form and widened the funnel. Separately, we helped close communication with a parallel internal candidate respectfully, without burning bridges.
Outcome
A strong finalist joined; after the first month the client gave positive feedback. The search stopped stalling on a marker technology.
Principle: First clarify what task a requirement serves — and only then search by technology.
ML / Data ScienceRetentionHard conversations

Case 2: reworking compensation — and keeping the specialist

The business challenge
After the acute hiring phase the project stabilised and the team filled out. A delicate request appeared — to rework the compensation of a strong but “expensive” specialist without breaking trust or triggering an exit.
How we worked
We helped turn a risky “cut the pay” request into a correct conversation: recognition of contribution, the reasons for the change, an honest assessment with growth areas, a development plan and a review horizon. We brought the dialogue back into an “assessment plus development” frame, suggested a tone without devaluation, and afterwards collected the employee’s feedback.
Outcome
The employee stayed and accepted the new terms, with clear directions for growth. A risky moment became a managed development plan.
Principle: Hard conversations hold up when there is respect, clear reasons and a plan for growth.
Project managementOffer stageEthical communication

Case 3: managing uncertainty at the offer stage

The business challenge
At the final stage a candidate (a project manager) asked for a salary review, while inside the company an abrupt withdrawal of the offer was being discussed — a step with high reputational risk.
How we worked
We restrained the impulse to “pull the offer without reasons”, explaining the consequences; we proposed gathering facts first and building a correct communication scenario. We kept the negotiations transparent, clarified what was critical for the candidate, gave the client time for a considered decision, and helped clarify the role boundaries.
Outcome
The candidate confirmed readiness to accept; the final stage passed without reputational loss or burned bridges on the market.
Principle: An offer is an instrument of trust; at the final stage facts and careful communication decide, not abrupt moves.
C++ / QtProbationOnboarding

Case 4: doubts during probation — facts instead of feelings

The business challenge
Towards the end of probation the client developed doubts about the developer’s autonomy. The risk was either cutting on emotion or dragging the decision out with an unclear outcome.
How we worked
We moved the question from feelings to facts: gathered structured feedback from the team lead, named concrete growth areas, and agreed an improvement plan with checkpoints.
Outcome
The decision became predictable for both sides — without threats or abrupt moves: the employee had a clear plan, the client had criteria.
Principle: Probation doubts are better resolved through facts and an improvement plan — then the decision is predictable for everyone.
Product analytics (junior)Screening designAnti-cheat

Case 5: screening a junior in the age of AI

The business challenge
We needed to hire a junior analyst and assess skills honestly in a setting where test answers are easily “boosted” with an LLM.
How we worked
We built a calibrated junior screen: questions with clear markers (green and red signals), video-recorded answers, and explicit management of the “answers via AI” risk. We checked systematic thinking and communication, not memorised phrasing.
Outcome
The client got results comparable across candidates and protected against gaming — the hiring decision became well-grounded.
Principle: For a junior, what matters is testing systematic thinking and communication through cases with clear markers.
3D / PythonTransparent assessmentReproducibility

Case 6: an honest, reproducible technical assessment

The business challenge
We needed to assess 3D/Python candidates so the result did not depend on “boosted” answers and was reproducible for the client.
How we worked
We built a transparent scheme: clear rules, an independent expert review, and a final validation. We did not complicate tasks for the sake of it; we made the check repeatable.
Outcome
The assessment became protected and comparable; the client decided on transparent, reproducible data.
Principle: The winner is not the one who makes tasks harder, but the one who makes the check transparent and reproducible.
Infrastructure / SysadminOffer stageOne clear line

Case 7: one clear line of communication at the offer stage

The business challenge
At the offer-and-rejection stage the client’s position became inconsistent and “wavering” — a risk of confusing the candidate and harming the company’s reputation.
How we worked
We held a single line of communication: did not “think for” the client, carefully synced the status, and closed the situation with the candidate calmly and correctly.
Outcome
The candidate received clear, respectful communication; the situation closed without negativity or reputational loss for the employer.
Principle: At the offer and the rejection, what matters most is holding one honest line — and not thinking on the client’s behalf.

What clients say

Real reviews from The One clients. Original Russian-language quotes preserved on the-one-hr.ru.

I worked with The One on two IT roles. The experience was positive across the board. The team doesn't grab every opening or promise the moon — they read the brief carefully, analyse the inputs, and only then say whether they'll take it on. All relevant context was considered up front. Recruiters showed relevant candidates. Status updates landed in chat in real time. The team lead is genuinely focused on process improvement — Anastasia asked me for a retrospective and we honestly discussed what went well.
HR Manager Uniscan Research
We came to The ONE with a very difficult role — a lead R&D engineer for a science-intensive instrumentation company in a non-trivial location. For the first time I encountered agencies that weren't ready to take on our complex vacancy. The ONE took it on, with flexible commercial terms. The role was closed in remarkably short timeframes. Thank you to Anastasia for a mutually beneficial collaboration!
HR Manager Ecomer
We were referred to The One by colleagues who had positive experience working directly with Anastasia Vasiliadi, the agency founder. We needed to hire not just one developer but to build a team, so the founder's hands-on background was a plus. Our company is part of a bank's ecosystem with strict standards, so we evaluated carefully and compared with other agencies. We asked for anonymised candidate communication examples — they delivered. All commercial terms were captured in the contract as agreed.
CEO ООО «Автоэкспресс»
We approached The One to find an engineer — a very time-consuming task for us internally. The team was professional and organised: brief filled in quickly, kick-off call, search started. The work was clearly structured, with platform access for funnel visibility. We only needed to attend technical interviews — there were three. On the third interview we found the right candidate. At wrap-up we received a detailed feedback report that will help us shape our employer positioning. We'll definitely work with them again.
CEO ООО «Сэйв Технологии»
We came to The One with a request to source CVs and schedule interviews with relevant candidates. We needed a high volume of interviews to run expert selection in-house. That format isn't common in the market, but The One took it on. In one month The One arranged 38 interviews with relevant candidates — 75% of the project plan, which we considered a success. We appreciated the professional approach and fast feedback. They also helped correct our job description even though it was outside the contract scope. Special mention to the careful approach of the agency lead.
