Deloitte Business Technology Analyst interview questions

My Deloitte interview situation was honestly mediocre in comparison to my Deloitte recruiting experience (which was very extensive and wonderful). I had three thirty-minute back-to-back interviews at my university campus; the first was a behavioral, and the second and third were both case studies. The behavioral interview was unusually brief, and the case interviews were much more technical than I was expecting after reading other interview reviews on here (and in my opinion, much too difficult for any college student to confidently and knowledgeably answer). The interviewers seemed cold and had little to no interest in the interview, and there were no female interviewers. I got no replies from the interviewers after sending followup emails. I personally found them rude and felt they had already pre-selected who they wanted to hire prior to even conducting interviews.

2 technical, 1 versant, 1 manager, 1 hr. Interview process was good. They called me in morning and end up everything till evening. There is one additional round as Versant test. This will check candidate's communication skills in all the areas i.e. reading, speaking, writing. Every round is eliminatory round.
