Roamware interview questions !

Few questions from Roamware interview . Although it depends on who takes your interview. These were the questions asked to me :


1). Write a program for Binary Search.
2). Differnce between macro and constant.
3). what is #?
4). Difference between index and primary key?
5). Different types of joins in relational database.
6). Write a sql query to find the name of employee who gets second highest salary. The tables are :
         EmpDetail { EmpId, EmpName}
         SalaryDetail {EmpId, Salary}
7). SS7 description
8). SCP, SSP, MSC, VLR, HLR related basic questions.
9). Call flow and the various components interfaced during a call flow.
10). If a subscriber has placed a call to another subscriber, and some oss feature is comes in picture during the call, what would be the process of charging in case of prepaid customer.

But anyways, Roamware will try to ask you more and more difficult questions to lower down your salary expections. They can hire you if you can join them in 10% to 20% hike.
