The first round consisted of a set of very simple questions to answer on the phone, as others have mentioned.

Additionally, I was asked about what is mutable/immutable among tuples, dictionaries, and lists.

The second round was a Skype interview with one of the engineers. It began with brief questions about my resume, projects, and preferred programming languages.

This was followed by a series of questions touching various subjects and concluded with a programming assignment.

Remember to check your code very carefully to avoid bugs, as you may tend to get nervous about time running out.

Questions:

• Memory management (implementation of a garbage collector)
• Compilation of Python code
• What happens when a URL is typed into the browser
• What can be done to speed up a SELECT query

A couple of other questions I'm having difficulty recollecting, and a coding assignment towards the end.
