Independent Client Evidence
Client Reviews & Career Results
This page brings together the independent evidence for Eich Dyn Career Services and Career OS™ in one place: customer reviews published on Trustpilot, service reviews published on LinkedIn Services, and the documented outcomes clients have described after working through the Career OS™ methodology with Dai Jones. The reviews relate to career consulting work — career diagnosis and positioning, CV and LinkedIn profile work, interview preparation, and salary negotiation — for experienced professionals, technical specialists and senior leaders. Historic engineering-leadership recommendations for Dai Jones are deliberately excluded; only career-service evidence appears here. Outcomes are individual client experiences, not guaranteed results.

First-hand client experience
Every review below was written by someone who worked directly with Eich Dyn — not by us, and not by a third-party copywriter.
Named professional context
Most reviewers are named, with their role and seniority visible, so the evidence can be read in context.
Specific documented outcomes
Where a client described a measurable result — an offer, an uplift, a transition — it is reported as they described it.
Independent platform verification
Trustpilot and LinkedIn Services host and moderate the reviews. We do not control what is published there.
A clear line between the two
Platform figures and client words are labelled by source. Eich Dyn's own claims about Career OS™ are made elsewhere on this site, and kept separate.

A note on outcomes
Individual career outcomes vary by market, role, level of experience, preparation and the client's own execution. The examples on this page are evidence of what individual clients experienced — they are not guaranteed outcomes, and nothing here should be read as a promise of a specific offer, salary or timescale.
