For the part where it is too important (interview), you are concerned more about it and think exaggeratedly about anything and everything. The crossing black cat and associated bad luck here could be a self fulfilling prophecy. For a trivial task you would not give it much thought and the crossing black cat would not matter much.

Consider you being an ambulance driver and attending an emergency call. The black cat crosses your path but you cannot change the route because it is the shortest one. You would do everything you can to save a life.

The point is - harder you work luckier you get.

That is correct, as you portrayed here, the cruciality of task at hand may surpass the beliefs. I am quite certain, this ideology is persistent.
