The interview was first done with online coding test, which was followed by a technical phone interview. During the phone interview, I was assessed with different analytical problems and was asked to go through each step of solving the problem.

As everyone said, you have 3 parts. The online test, which is decently hard because of the time pressure, but doesn't require any previous knowledge of software. Then a phone interview, with two questions, the ladder egg fall and the correct bracketing. Then an on-site interview with four questions. An implementation of a maze path finder, of an alarm, of two robots parachuted in the desert who have to meet each other, and some code in Ruby. The former ones are in some invented language.
