Hexagon Software Analyst interview questions

I attended through a referral drive. my resume was forwarded to HR by an intergraph employee and i got a call for the interview process. usually any drive at intergraph if 600 people attend they will select max 10-15. the first round will be a written test with 2 papers - aptitude and C,C++. It won't be much difficult. cut off will be different for ,,C++ based on branch. next round will be technical. pretty good questions (based on interviewer!!). usually 2 rounds of technical interview might happen. completely on C, C++, data structures and SQL(if u r from Computer science background) last round will be HR. just be cool and answer very simple questions. make sure you communicate well.
