Instructions:

After you have completed these questions, you will be given a per-topic evaluation, as well as an overall recommendation on whether your technical skill do meet the requirements to participate in the second day of the Business Partner Training. We want to encourage you to participate in the first day independent from the Pre-Assessment results.

Please keep in mind that this recommendation is based on evaluation of the brief questionnaire. Typically, although not certainly, the evaluation properly estimates the skills of individual candidates. If you believe that this evaluation has underestimated or overestimated your skills, you may choose to be more daring or more cautious in the trainings you choose. Ultimately, you may well be the best judge of your own skills.
