Atos Associate Engineer interview questions

couple of technical round and 2 manager round and 1 HR round ...this has been done twice with me. They keep you on hold for long time even after your successful interview Until someone from manager reference not comes

They first used to take generally written test. If you got good score in the test then they ask to come to for the interview. I passed their test where they asked math, English and some general question. They asked me to come for the face to face interview there they asked my overall experienced and after one by one they took individually to every candidate to separate room and they start asking questions. I had system engineering background so they asked me accordingly such questions where I given then answers. And they told me you are got selected and would have to sign a bond and 25000 INR for security for two years after that I was ready and they did not asked money but sign a bond and I had got that job as Associate engineer.
