Some employees will not/are unable to help you with questions (Knowledge and attitude is questionable).
On Call system (May have to work weekends and throughout the night).
Meetings, so many meetings.
No guidance (in my experience with no knowledge on the specific task) on how to do your job. They also expect you to be a complete self starter and understand what will need to be done in each sprint and come up with your own tasks for each sprint when usually (from what I've been told) to more senior members would assign you tasks to allow more structure.
