Zoek, vergelijk en bereid je sollicitatie voor

Begin met een beroep of vaardigheid die je wilt gebruiken. Pas de locatie- en beroepsfilters aan en open vacatures om de verantwoordelijkheden te vergelijken. Vind je geen resultaten, probeer dan een kortere zoekterm of verwijder één filter tegelijk.

Maak onderscheid tussen vereisten en voorkeuren. Controleer werktijden, beloning en locatie wanneer die zijn vermeld. Ook werk op afstand kan een bepaald woonland, een werkvergunning of overlappende werktijden vereisen. Bevestig de beschikbaarheid en volledige voorwaarden bij de werkgever.

Kies echte voorbeelden uit je ervaring die aansluiten op de functie-eisen. Leg je bijdrage uit en gebruik alleen cijfers die je kunt onderbouwen. Volg de instructies van de werkgever en controleer contactgegevens, inhoud en PDF voordat je de sollicitatie verstuurt.

Voordat je solliciteert

Vragen over werk zoeken

Waarom zijn sommige vacatures in het Engels?

Werkgevers schrijven hun eigen titels en omschrijvingen. We behouden die teksten om de vereisten en voorwaarden niet te veranderen. De navigatie en deze gids zijn in het Nederlands. Vind je niets met Nederlandse zoekwoorden, probeer dan ook de functie of vaardigheid in de taal van de vacature, bijvoorbeeld “software engineer”.

Kan ik bij een baan op afstand vanuit elk land werken?

Niet altijd. Een werkgever kan bepaalde woonlanden, een werkvergunning of vaste werktijden vereisen. Controleer de oorspronkelijke vacature. Ontbreken deze gegevens, vraag dan om bevestiging voordat je aanneemt dat je vanuit jouw locatie kunt werken.

Wat doe ik als er geen resultaten zijn?

Probeer een bredere functietitel of één vaardigheid en verwijder de filters één voor één. Bedrijven gebruiken verschillende namen voor vergelijkbaar werk. Is een specifieke vacature verdwenen, zoek dan het referentienummer op de carrièrepagina van het bedrijf. Minder filters maken een gesloten vacature niet opnieuw beschikbaar.

Wordt mijn sollicitatie via ResumizeAI verstuurd?

De sollicitatieknop opent een externe website. Volg de instructies van de werkgever of het wervingsplatform en bevestig daar de verzending. Een cv voorbereiden in ResumizeAI is nog geen sollicitatie indienen. Opent de link alleen de bedrijfswebsite, zoek dan eerst de juiste vacature.

Hoe pas ik mijn cv en motivatiebrief aan?

Koppel de vereisten aan projecten, taken en resultaten die je kunt toelichten. Benadruk relevante ervaring zonder vaardigheden of prestaties te verzinnen. Leg in je brief je interesse uit met een concreet voorbeeld. Gebruik de gevraagde taal en bestandsindeling en controleer beide documenten voor verzending.
