Deutsche Bank Developer interview questions

Worst interview experiance I ever had. It's technically still ongoing even though I have given up hope. I was approached by an agency for the opening and they had scheduled the interview. It was actually a walk in though. And they tested all applicants, even with more than 5 years of experience. Afterwards the HR told me that I had passed the test but they have no one to take in interview and thus he'll arrange for a telephonic interview. After this there was a gap of almost a month in which I kept following up with agency. After this they asked me to appear in person again for the interview. Which I did and cleared as well. The interview was quite easy. The HR said that there will be a fitment round with some VP after that and thats the last communication I had with them. I followed up with the agency again for a few weeks but they have given up as well. The HR team is really bad with timely communication. What if I had been on notice period, how can they stretch the interview process for that long?

It was a phone screen followed by an online coding session and then on site interviews. The interview was not trivial but also wasn't impossibly hard. They asked really good questions regarding Java. Things you don't always think about or use in your everyday coding but should know. They ask about computer science concepts you may not use day to day but should be aware of it. You should prepare with a good programming interview book before interviewing.
