Bloomberg Financial Software Engineer interview questions

For the moment, the process is on going. Previous posts cover pretty much what's in it. Online skills exams. Mostly logical and comprehension testing. The response for a phone interview came in soon after. This one was a bit tougher. Charades, some coding and details that go back to the basics.

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?
