I was invited to first round testing at McKinsey via my recruiter. The test was a series of times grammar, reading comp and spelling tests and three hypotheticals. The netx day I found out that I was being called back for 2nd round and would meet with an HR manager, two EAs and the senior-most HR Manager. The interviews were grueling in that you were expected to review the details of your resume over and over again albeit from a slightly different perspective based on the interviewer.
