The interview was pretty straightforward. It consisted of 3 rounds. The first round was to fill out a questionnaire describing how you would tackle on certain business cases. The second round was a recorded video interview in which you a specific business case was given to you and had to think on the fly to answer it. The third was a video interview with the recruiter where again they ask you behavioral and business case questions.
I interviewed for Mu Sigma in January 2020. The entire process took about 3 weeks. You first complete an online test that has 3 sections. The first section is taking a video of yourself answering various questions, then there is a multiple choice section and a case study. After passing the online test, they set up a video interview. Then there was an HR interview a few days later. The HR interview was when they extended the offer.
