The challenge
Jelle’s recruiters spent at least 60% of their day on screening and scheduling, and rejected 95% of applicants by hand before a single interview was booked. Every inbound application needed a recruiter before anything could move.
Candidates who didn’t fit the role were simply rejected, with no route to another vacancy. Incomplete profiles meant 15 minutes of manual intake per candidate, and recent interviewees were still being invited again.
The solution
Eva screens every candidate against the role’s real requirements on WhatsApp or by phone, including open applications, which she matches to suitable roles. Candidates who match get an interview booked straight into Outlook, right inside the conversation. Candidates who don’t are offered two alternative vacancies instead of a rejection.
After scheduling, Eva completes each profile in MySolution, so candidates arrive interview-ready. Before going live, Jelle tested her against blunt, confrontational messages to get the tone right: direct, plain and no nonsense, the way Rotterdam talks. If an interview can’t be booked within the 24–48 hour target window, MySolution alerts the team and a recruiter takes over. The hiring decision always stays with a Jelle recruiter.
The data behind the placements. During screening, Eva also asks candidates what they’re looking for. Jelle built its own matching engine on top of that data: every completed profile is matched against every open vacancy across Jelle’s client network, recruiters see all the options for a candidate at a glance, and the right client contact is notified when a strong candidate comes in.

The results
In October 2025, Jelle moved to MySolution and took Eva offline for one planned week. The team couldn’t absorb first-contact screening by hand anymore, which made one thing clear: Eva isn’t a bolt-on tool.

"When Eva went down in October, there was total panic. They couldn’t do it anymore, there was just too much. Before, they always used to do it. But after Eva, they didn’t know how to fit it into their work anymore."

"Sometimes people invite her to come over. They compliment her for working at night and tell her she can go to bed. They’re worried about her. That’s how real she feels."
