Its all attitude. If you have a good one you'll be fine. There will always be a certain amount of friendly "harassment" no matter what amount of time you have. There will also always be a few jerks in any career field that want you to be as miserable as they are. However if YOU are the jerk or have an abrasive personality then you may be given more than subtle encouragement to take your attitude elsewhere. Remember that in this business everyone generally loves pilots who are junior to them unless they are given a strong reason not to.
