How do I prepare for psychometric tests in the application process?

Psychometric tests come in three main forms: personality tests (Big Five, MBTI, DISC), cognitive ability tests (logical reasoning, numerical, verbal), and Situational Judgment Tests (SJTs). Preparation according to ISO 10667-1: Cognitive ability tests are trainable -- practice improves results by 0.5-1 standard deviation. Personality tests: Answering authentically is better than optimising -- tests detect impression management and score it negatively. Best free resources for Germany: JobTestPrep (online), SHL Practice Tests, Assessment-Center-Training.de. Legal situation: BDSG Section 26 -- test results are personal data, and you have the right to access them. Under AGG: Tests must be job-related and non-discriminatory. Most common mistakes: Spending too long on a single question (time management), faking personality tests (which gets detected).
