Heat an ovenproof griddle pan until very hot. Season the beef fillet. Add the olive oil to the pan and then add the beef and brown well for 10 minutes on all sides until you have achieved a nice, thick crust. Remove from the heat and leave to stand in a warm place until the beef has relaxed. This will take at least 10 minutes, but you could leave the beef to stand for up to 2 hours, provided it is not in too hot a place.
