This List Is In No Particular Order:
1) High employee Turnover, willing and unwilling.
2) Lack of process, procedures, documentation.
3) Sink or Swim mentality and no available training or docs for training
4) Unknown/Vague Expectations with no guidelines to measure personal performance
5) Internal Political Tension
6) Due to # 1-thru-5 above causes constant stress over job security.
Pass on employment here if you can! I am one of many who have been extended this critical and very true advice! Ethics goes right out the window here, whether you are planning a long term commitment or a shorter one, you will be treated as if you have one foot out the door. Probably for a good reason, they have left that foot out there for you! If you must take the job and I hope you do not, you should absolutely continue your job search as they have no loyalty to you and seem to be OK with this modus operandi. If you are a rock-star you threaten someone working there; if you are not, then you are an unnecessary burden (on the budget or someones' time). In what I have witnessed there seems to be a no win situation except whatever serves their need at the time.
There is no feeling of job security, this is NOT a grudge but the simple truth.
