It was a pretty standard process for a grad program application: online application, game-based psychometric testing, then a hirevue video interview. They say you can't 'study' for psychometric testing but most online IQ games mimic the types of games they give you, so they're useful to prep.

The Unilever graduate interview process typically involves an online application, online assessments (including personality tests and sometimes game-based assessments), a pre-recorded video interview, and an assessment day at the company's offices. The video interview usually includes competency-based questions and a case study related to the specific role. The assessment day may involve further evaluations, discussions, and potentially an overnight stay for convenience.
