SAP Software Developer interview questions

first they called me on phone for an interview; it was pretty easy. Then I was invited for an onsite 1 on one interview in CA. It was pretty difficult. They asked a lot of technical questions on C, C++ and databases. They also asked me to write a couple of programs and gave 5 mins for each one of them.

good as good, tough first rounfd then all the rounds are easy, first round basic, second round another basic and lil advanced round, third round will be problem solving, HR round and if necessary final will be an VP round
