I was contacted quite fast after sending resume second time. The first e-mail was just missed (i hope). Interview was about 60 min where i was asked about typical usage of operation systems (Windows, OS X). Then were several generic questions about Java, Python and shell scripting. Then i was asked to solve several tasks (three A4 papers) on Java and Python languages such as: Write simple program which "doing something", guess result of Java code snippet and so on.
