Pros
The content they work on is interesting. Because it's a small company, you can work in several different roles simultaneously and learn about all sides of the localization process. Most people there are nice and talented, and you get to work with people from different countries. The company delivers very high-quality content. The pay is not bad for a small company.
Cons
The work is disorganized and unnecessarily complicated. There is no translation memory for most marketing tasks, so project managers must search through all past tasks/existing content manually to find similar copy, even if that means looking through dozens upon dozens of tasks. It wastes a ridiculous amount of time and energy, and is embarrassingly low-tech for a company with high-profile clients. A lot of the company's documentation is scattered throughout a mostly unorganized google drive in different languages, so trying to locate the correct manual or instructions for something is difficult (and in most cases, you're not even sure if instructions exist, so you're just searching blindly). There's no real procedure for training new members; either you get assigned to a senior team member who personally walks you through everything while they work, or you get random outdated manuals thrown at you haphazardly by no one in particular. If senior team members are too busy to train, you're just left behind. Employees are expected to work overtime with no extra pay or benefits. Almost every member is given more work than is possible to complete within their work hours and will be criticized within the team for passing off projects to other employees upon signing off. Thus, the most successful employees at the company are the ones who are willing to dedicate all their free time and devotion to the company without getting anything in return. Team members will grow dissatisfied with other team members who they feel are "not taking on their fair share," even if those other team members are working hard for a solid 40 hours per week, because the expectation is to be working more than that. There are no employees on call for deliveries over the weekend, so if a task is due on Saturday or Sunday morning, whoever found it is expected to come in and deliver it. It's the same environment of any other toxic Korean workplace, wearing the cloak of a progressive silicon valley startup (although I suppose, to be fair, startups don't have a particularly good rep either). The company will hire and keep people who have poor attitudes and a weak work ethic due to "talent," forcing all other team members to clean up their messes. The company will hire people who have no prior experience in the field, in many cases because they are close friends or family with another member of the company. The company will give promotions to employees who have made big mistakes, while simultaneously chiding other employees for much smaller mistakes. Higher-ups will criticize employees behind their backs in front of other employees. Team members are encouraged to nitpick other team members' work and call them out on their "errors," even if the errors were so small they had to effect whatsoever on the success of the project. All of these things lead to very low morale.
