Before the personal interview there is a test in programming, you can take it in: Java, C, C++, C# or Python.

The questions will be the same in all languages.

In the first one you need to implement a binary search in a binary-search tree, pretty straightforward.

In the second question, you get some methods in a library and must call them properly to get the system to run.

In the third question, you need to correct mistakes in an almost-finished system's code.

In the fourth question, you need to return the IPs that sent more than 10% of the messages in a system, and you do this with a hashtable.
