This depends on the situation...
for example if they are unconsious, you should check to see if their chest is moving - by looking down their body at horizontal, or place your ear near to their mouth, to see if you can hear them breathing
If the victim is breathing normally, but not responding you should
When checking for breathing you look for normal breathing. lis two types obreathing that you consider

Up to (but no longer than) 10 secs
tilt their head gently back to open up the passage way, put your hand with small amounts of pressure on top of the heart area, and put your ear close to their mouth to hear for breathing, and watch to see if their chest moves up and down.
The statement is false. CPR should only begin if the patient has stopped breathing or if their heart has stopped beating. While it is likely that a choking victim has ceased breathing if they have lost consciousness, it is not an absolute indicator.
When beginning mouth to mouth respiration, you should start by assessing the victim with the ABC's (Airway-tilting the victim's head back to ensure open airway, Breathing-make sure that the victim's chest is going up and down that means the victim is breathing, Circulation- check the victim's pulse) If the victim is not breathing, skip checking the pulse and start CPR. First, give the victim two breaths. Breath in and out when giving the breaths just as you would when you breath regularly. Then, start giving the victim CPR pumps or whatever you call it when you pump the victim's chest. This is all I can tell you- I am a lifeguard and if you want to know all about CPR you need to be properly taught. :)
Watch the victim's chest for 15 seconds or more. If the chest rises - the victim is breathing. If not - start artificial respiration.
Yes you should put a victim in a recovery position when victim is unresponsive and breathing.
