Pros
People are experienced pros on the whole. Tentpole projects. Paid for every hour you work with an OT rate for excessive hours. Usually high pay rates for overseas workers. Decent catering. Good parties.
Cons
Extremely short deadlines and mercurial decisions, leading to long hours for long periods of time and panic actions. Not a very cohesive company with each department having a different culture and questionable inter-departmental relations. Very little training and mentoring. Extreme pay differences between local and overseas workers. Supervisors seem to play favorites with work distribution and advancement. Poor pay increases, if any. Have had some poor on-screen credit classifications for outside clients. Weta Digital doesn't seem concerned about instilling loyalty or retaining personnel for the long haul. Recommend you work there for short-term projects and get out.
