Deutsche Bank Senior Analyst for .NET interview questions

I went for .NET developer role on 6th Feb 2016, It consisted 2 round for that day, 1st was written one. which was good coding question paper, in 25 min you have to attempt 25 question of c# and in other set 25 questions of SQL in 25 min. After second round they were telling everyone HR will get back to you. Later they called for F2F round whoever cleared their written. Interview questions are good, they asked some very basic questions and some scenerio based questions. Later HR told they will call on Monday to discuss further round. That monday never came :P. I read reviews afterwards in glassdoor they do this only to most of the time, why they conduct interviews then, waste of their time and our as well.
