There was three interviews. 1 via skype and 2 face to face. Simple questions about web-technologies: php (design patterns, what is new in 5.xx version), mysql (indexes, queries, engines), nosql technologies, algorithms (a time complexity, different sorting algorithms, some examples of classical maths algorithms), web-frameworks (pros and cons of the framework, that you use in your everyday work proccess) Some management questions (about development proccess in your current company, how it is built, about vcs and bugtracking system, about interactions with other members of your team (managers, developers, etc...)) Very friendly atmoshphere and enjoyable.
