Bit mismanaged, the recruiter informed me that the interview would consist of basic math /logic test followed by F2F interview. Instead I had a F2F interview first followed by a Semi advanced math/Data analysis / Grammar test. God - i thought wren and martin was history but post this test I was forced to come back and refer to this Grammar goddess . To me this test format is really old and Nielson's are busy to change it. Who on earth cares if its nielsons's or nielson's strategy - this is one of the questions of grammar test. Well, post interview no one inform if u made it or not and for what reasons. I had a good interview round and may have missed by 1 mark or 2 on the test as it went off well as well.
