02 · The challenge

The context

Opening on a fixed datein a tight labour market

Project Circle is an innovative plant, unique in Europe: it turns spent grain from the Heineken brewery into green energy and food products. It had to start with a full team, running continuously from day one.

  1. A tight industrial labour market

    In the Hauts-de-France, few profiles are available locally in these operations and maintenance trades.

  2. 24/7 operation with continuous firing

    The entire shift team had to be hired at the same time to ensure operational continuity from start-up.

  3. Shortage profiles

    Electrical and mechanical maintenance technicians, automation engineers: profiles very rare on the market, and even more so for a new plant.

  4. A start-up date that cannot slip

    Opening planned for September or October 2025, with a risk of significant contractual penalties in case of delay.

What the client says

Volta is a highly committed partner alongside Idex. At first, we tested it successfully on hires in a difficult geographic area where we had been without a solution for several months. Having proved satisfactory, we were able to entrust it with more searches and Volta delivered again. It is a partner that takes care to understand the client’s needs properly upfront, which is a guarantee of efficiency and of candidate selectivity.

05 · The method

The Volta Executive method

Four stages,kept across fifteen roles at once

A 1-hour scoping session and a scorecard, the mapping of the search ecosystem, a shortlist within 10 days, a hire within 3 weeks. The 3 weeks run from scoping to the chosen candidate with the offer accepted, when the five key success factors are in place. The candidate’s notice period, often three months for a manager in post, comes on top.

  1. Day 1

    A 1-hour scoping session and a scorecard

    One hour with the future manager, not just HR. We come out with the three results expected at twelve months, the real budget including variable pay, and a scorecard ranking each skill: essential, necessary, useful, bonus.

  2. Days 1 to 3

    Map the search ecosystem

    The companies, sites and roles where the profile really exists: competitors, suppliers, customers, neighbouring sectors doing the same job under another name. We know how many people fit the scorecard before writing the first message.

  3. Within 10 days

    A shortlist within 10 days

    Three to five candidates approached directly, met, assessed against the scorecard by an engineer, presented with their motivations and real salary expectations. Not a pile of CVs.

  4. Within 3 weeks

    A hire within 3 weeks by direct search

    Two interview rounds at most, with the direct manager. The package and the counter-offer are prepared before the final interview: the offer goes out within 24 hours and the chosen candidate says yes.

A project team in 48 hours

Immediate launch of a dedicated team of five experts, with one point of contact for IDEX, who leads the entire assignment.
