Nielsen Manager interview questions

Applied and had three rounds of interviews in the next five working days followed by a SHL test (17 questions in 18 minutes, ran out of time). Interviews felt like they went but apparently rejected because of the test. If that's the real reason, a time bound test with barely a minute per question is a ridiculous way to gauge candidates. HR was helpful and responsive during the process but only communicated the rejection a month later, after I followed up.
