congratulations mess ups are going to happen everyone messes up sometimes especially in a new job  as a manager what i look for is how the new hire deals with the mess up   own your mess up when it happens  dont take correction personally correction is just part of learning and whoever is giving it to you is trying to help you succeed let them know that you understand why it is a problem and then reassure them it wont happen again with what change you will implement to make this change    so if you put bread on the bottom of the bag and your trainer said op bread needs to be on top or it gets smushed  you would respond thank you for pointing that out i can see how upsetting that would be to the customer  i am going to start setting lighter items to the left and wait until i have packed all the heavier items to make sure it doesnt happen again  also if you can bring a small note book and pen to keep important notes in  the act of writing down important information helps us retain it  you dont want to have it out all the time or have it distract you from work but taking small notes on break or during meetings also shows the manager how invested you are in learning how to do the job to their specifications  youve got this
