I applied via nielsen web site. It took 1 week to arrange a meeting - first stage of the interview is a test. The test consists of 3 parts - the first is logical, the second - basic math and some economical issues, you have to be aware with price elasticity, the last - problem solving. The time you have for the first stage is 10min., for the other parts - no limitation. I couldn't finish all the tasks in the first stage for the given time. I don't know if I passed the test, i am waiting for the feedback from the Company.
