Wie funktioniert Instaffo? 🤔

Instaffo ist eine smarte Job-Plattform, die dich mit passenden, aktiven Jobs verbindet. Du chattest direkt mit Unternehmen oder lässt dich zuerst von ihnen anschreiben. Instaffo ist für dich kostenlos. Viele Jobs sind in Deutschland, aber es gibt auch Remote-Optionen innerhalb der EU.

Wie viel kostet Instaffo? 💰

Instaffo ist für Jobsuchende völlig kostenlos. Keine Abos oder versteckte Kosten.

Kann mein aktueller Arbeitgeber mich sehen? 🔒

Nein. Du entscheidest, wer dein Profil sieht. Dein aktueller Arbeitgeber (und andere, die du blockieren möchtest) werden ausgeschlossen.

Wie lange dauert es, bis ein Unternehmen auf meine Bewerbung antwortet und mit wem spreche ich? 💬

Du erhältst normalerweise innerhalb von 24 Stunden eine Antwort vom Arbeitgeber über den Chat auf unserer Plattform. Und keine Sorge, du wirst nicht mit Headhuntern oder Personalvermittlungsagenturen sprechen.

Muss ich in Deutschland leben? 🌍

Nicht unbedingt. Viele Jobs sind in Deutschland angesiedelt, aber einige erlauben Remote- oder Hybrid-Arbeit. Die meisten Unternehmen suchen Kandidaten in EU-Zeitzonen, und einige erwarten deutsche Sprachkenntnisse.
