I first met two software developers at a career fair for my university. I was asked to write some code for the FizzBuzz problem.

The two came back to my university around a month later to give on-site interviews. I talked about my programming experience, and they asked some more difficult programming problems.

Finally, I was offered an on-site interview, which lasted from around 9 a.m. to 3 p.m. I met with mostly technical people: the software manager, the quality assurance manager, and other engineers. Except for the question, "Why are you interested in quality assurance?", everything was related to programming and software development. I enjoyed talking about the technical questions, and the lunch was great.

Jump primarily uses C++ and Python. It would be good to respond to the programming questions in one of those languages.

You're given a string of messages from a stock exchange. It's in some format like "{orderId=|}{orderId=|}{orderId=|message}...". All the orderIds are unique, and no message will have a "|" in it. Write some code that, given the orderId, returns the message associated with it. How would you test the code you wrote and what would you test? (data structures)

Given a binary search tree, determine the closest common ancestor of two entries in the tree. The closest common ancestor of x and y is the node with the greatest depth that is an ancestor of x and y. (data structures)

I was given a C++ header file of a List class. It's essentially a LinkedList that requires insert() and remove(), except the insert() function has additional conditions. Implement those functions. How would you test the data structure? (software design)

I was given a whiteboard eraser and asked to define it and explain what it is. (software requirements)

I was given a diagram of how Jump's software system typically communicates with an exchange. I was given a scenario in which some output was wrong and asked what steps I would take to try and determine the source of the problem. (debugging)
