Pros
NOTHING apart from the only pros are the kind/talented artists working there.
Cons
Everything from the contract, salary, work hours, and holidays to the worst supervisor/boss who has absolutely no respect for you is terrible.
The unrealistic deadlines and pressure they put on you to force everyone to work until 10-11 pm. You will work from Monday to Saturday, with work hours from 9 am to 8 pm (usually ending up doing 2-3 hours of overtime), meaning you finish around 11 pm.
The salary is awful, and considering how expensive rent is in HK, this is not worth it.
He is taking advantage of recent graduates , offering them the lowest wage possible.
Even if this is your first job, the state of the movie is nowhere near completion. Therefore, you won't be able to use anything in your portfolio.
Additionally, this is not the first experience in the animation industry you are looking for. You will not learn anything but disrespect.
PLEASE stay away from this company, consult with artists who worked there in the past on LinkedIn and you will know what it's like.
