First I had to do an online Java test. Then I got a phone interview. The basic questions were about Java, C++, C, Unix, Data Structures and brain teaseres. Be prepared to on the general common topics for C++, JAVA and C as templates, exception handling, polymorphism, inheritance. You must be able to explain everything in details and to show a thorough understanding of the concepts. Question: A frog is at the bottom of a 30 meter well. Each day he summons enough energy for one 3 meter leap up the well. Exhausted, he then hangs there for the rest of the day. At night, while he is asleep, he slips 2 meters backwards. How many days does it take him to escape from the well?
