No real engineering occurs here. There are no architects leading projects. It's a bunch of individuals that just happen to be working in a group. There is no leadership, yet your tasks are dictated to you by management. There is no collaboration between engineers. The original HR crew (Link-a media) was replaced by Korean selected HR personnel, they don't give one iota of a care to the employee. They are strictly there for the company.
Security gets in the way of doing your job.
Wrongly implemented agile work environment is a train bearing down on you, and you are tied to the tracks. Micromanaged to the hilt.
And a key point. This is the Silicon Valley. In the USA. Not Korea! What good is it to hire the best and brightest, then handcuff them.
Don't work here. Find another place.
