After the traineeship ends, the decision whether you can continue with the same company belongs to you and the company. It's possible that you are offered a permanent position, but it is not a guarantee.
However, after you finish your Digital Explorer traineeship, the project team will provide all the help and tools to find your next career stop in your home country by organizing activities like career counseling, job fairs, bootcamps, and more. The support by Digital Explorers does not end after your traineeship.
