1. 30 minute behavioral, 30 minute technical. Behavioral interviewer was quite friendly, it was more like a conversation. Typical questions like What role do you play in a team etc. Technical interviewer was quite cold which was unexpected from Deloitte for me but maybe it's only normal by industry standards. Basic questions from data science, 2 SQL queries, 1 probability problem. 2. Take home 8 hour Case Study assessment (data science problem - visualization, modeling and estimation showcasing results) + Presentation 3. 30 minute Behavioral, 60 minute Technical (where you present your case study followed by QnA), 15 minute interview with Partner. The whole interview scheduling seemed very rushed, and I got my scheduled interview slots typically within 36 hours of the interview. Candidates also had to fill out forms and take the Pyrometrics assessment (which was interesting) in a day's notice which is fine, but I think they could give us more buffer time. It would be expected from an established firm as Deloitte. I got through the Take Home Assessment but cancelled my 3 remaining interviews when I got another offer, only because they repeated the whole "notify late" process. I think candidates also deserve more respect for their time.
