I applied through a recruiter. The process took 1 day. I interviewed at GPS Tuner (Budapest) in May 2016
Interview
You receive a piece of paper with questions. You get one hour to answer the questions with a pen. No other materials can be used. There were questions containing C code. To understand, to create.
Then follows interviews separately with the manager, project manager and the senior development manager.
They ask for a reference, which they later contact.
