Deloitte Business Technology Analyst interview questions

I was called in for the first round interviews for the Business Technology Analyst position. There were basically two rounds of interviews. First round of interview was held on-campus. First Interview(SDLC): I was expecting it to be a difficult round. My interviewer read out a case to me and I took notes. He later asked me questions about how I would approach the case problem which was basically all the steps involved in SDLC. I laid out 8 different steps in the SDLC process and went in depth of each to be more descriptive and the interviewer asked me detailed questions about each step. I was getting a sense that it was not going that well as the interviewer said at the end of the interview that it was a interesting discussion:P Second round(Behavioral Interview): The questions asked were all behavioral. i.e. Explain a situation where you had to deal with a difficult team member. etc This round went pretty well. I think I followed back with my interviewers with a thank you note. And one of them responded with an "All the Best" reply. A reject e-mail was sent later that evening. The second day interviewers were held on-site the very next day.
