If you are drawing more than one bearing connected to another then you must draw the lengths to scale. If it is just one bearing then no scale is needed at all. Also remember that angles do not change with scale. Otherwise if I had an equilateral triangle and then halved it I would end up with a triangle which had only 90 degrees :(

No. For example a ship could be said to be sailing on a bearing of 045°. This gives the information that it is sailing in a north easterly direction and there is no need to draw to scale.
Bearing diagrams would usually be drawn to scale in order to give more information..
Example
A ship sails 40 km east from harbour H to B and then 30 km north from B to A.
How far is it from where it started?
Draw to scale using 1cm =10 km
40 km is represented by a horizontal line 4cm long from H to B.
30 km is represented by a vertical line thro`B, 3cm long finishing at A.
Distance from starting point is HA and is measured as 5cm.
Real distance from H to B is then 50 km. if required, a bearing could also be calculated using triangle HBA.

No, but a later part of the question may ask you to solve something requiring that your diagram was originally drawn to scale.

If the question requires a scale diagram it should say.

no, unless it asks you to.
