Applied on website Initial phone interview - about 30 minutes Homework assignment - took me about 3 hours Wonderlic aptitude test & non-technical coding logic test - about 2 hours Interview day: group problem solving activity, presentation, cultural interview, consulting role-playing exercise, technical interview
