The process started with a technical assessment online that takes 2 hours to complete where there is a code challenge that is basically a consume door events handler with the following description * We always start with a closed door. The remote control has exactly one button, with the following behaviour. * * if the door is closed, a push starts opening the door, and viceversa * it takes 5 seconds for the door to open or close completely * While the door is moving, one push pauses movement, another puish resumes movement in the same direction * * In order to make the door safer, it has been equiped with resistence-based obstacle detection. When the door * detects an obstacle, it must inmediately reverse the direction of movement. * * a string where each character represents one second, with the following possible values * * '.' No event * 'P' Button has been pressed * 'O' Obstacle has been detected * * As an example '..P....' means that nothing happens for two seconds, then the button is pressed, then there were no * further events.
