Deutsche Bank Analyst - Technology interview questions

I applied in September. I got an email on November 28th inviting me to their super day on December 1st. I ended up doing a total of 3 interviews within the same day. I got a call a couple of weeks later telling me that they liked me but wouldn't make a final decision until the end of the month. The end of the month came and I did not hear from them. The first week of the following month I received an email saying the job position had been filled and I was not selected. A week later I got a call telling me that I was receiving an offer. The whole process seems poorly managed. It was stressful to receive a rejection email only to be given an offer a week later. I am unsure if maybe the spots had filled up but someone decided to turn the company down and I was the next best candidate. I did, however, really like the people that interviewed me. They were all very smart accomplished individuals who were friendly and open. I'm supposed to get my official offer letter next week. I am unsure if I will accept. I really like the people but New York City is expensive and with my skill set I have confidence I could find more job options if this job does not pay well.

Applied online and then did the assessment centre. The experience was really good and quick. Got the offer 1 month and a half after I applied. Everything was very well organized.
