T-Systems Team Lead interview questions

Received email from consultancy regarding the interview. I was in impression that it will be a Scheduled drive, but actually it was a walk-in. It took more than half haur to enter the floor as I had make entry at tow places. There were huge number of people. And T-system people including HR were not able to manage the numbers. Interview was on fire come first basis. It took another 2 hours to start the actual interview. It was face to face discussion and, and I felt like interviewer is in hurry as there were so many number of people. They even didn't cared about asking about yourself.

at least 2 rounds if the interview, With HR, With hiring manager and can be also with german counterpart. regular IW questions, why did you applied, previous experience, how do youhandle different situations. weak and strong points. you dont always get the responsefrom HR recruiting person.
