None in particular for me, but employees are expected to be self-motivated, work independently, and not require much supervision. Probably not a good fit if you are wanting to be told what needs to be done and checked in on regularly, or if you have trouble managing your time. If you are having problems, it is expected that you will reach out to someone for help and/or communicate with management.
Sometimes the general workflow can be non-standard and occasionally a little frustrating (finer details of project requirements can change, scope creep sometimes happens) but these problems often arise at small shops in my experience, especially ones that are growing. Also, management has been open to trying new ideas/methodologies in this area.
