I interviewed at Siemens in July 2016. Total there are three rounds aptitude,technical interview and HR interview 1. First round was aptitude test , it comprises of both technical and quantitative part.I cleared first round 2. Second round was technical interview in which they asked about my project ,they gave me some puzzles to solve and gave some program to write on paper , I can't clear that round .

1) Group discussion 2) Personal Interview 3) Telephonic round 4) Verbal round Results are out after this 4 rounds This above process is for non technical customer support. For technical support you should be on the top at telephonic round.
