Tatjana Jovanovska-Sonnberger

Tatjana Jovanovska-Sonnberger is the Partner companies call when they are done gambling at the final hiring stage. She cuts through polished CVs and interview theatre and exposes how a candidate will actually behave once the pressure hits. In tech, professional services, banking, insurance, and fast-moving consumer businesses, she protects growth by preventing mis-hires that quietly drain profit, speed, and morale. While most organizations chase bigger talent funnels and hope something sticks, she narrows the field and focuses leaders on one thing they rarely see clearly enough: who will truly fit, contribute, and compound value over time.

Her edge comes from how she uses DiSC as a hard business tool, not a soft workshop exercise. Tatjana studies behavioral patterns, decision styles, and stress responses so leaders can distinguish between surface charm and reliable performance. She builds short, sharp processes that slot into existing hiring workflows and turn late-stage evaluations into confident, data-backed calls. Clients move from vague impressions to clear behavioral insight, from “we’ll see how they turn out” to “we know exactly what we’re getting and how to integrate them fast.” The result is leaner hiring, stronger teams, fewer costly resets, and roles filled by people who actually match the demands of the work.

When the stakes are high and a key role cannot be a mistake, Tatjana brings calm, precise judgment into the room. She operates with a clear lens, direct language, and zero theatrics so leaders get grounded, practical guidance they can act on immediately. Her work gives them relief from second-guessing, traction in complex hiring decisions, and the confidence that every critical seat is filled by someone who fits the business they are building, not the one they have outgrown. If you want final-stage hiring to be a strategic advantage instead of an expensive bet, you want her on your side.
