Pros
You become close with your co-workers because you're all going through the same difficulties. Similar to a pledge class, I suppose.
Kontras
TransPerfect's business model is based upon having people work as much unpaid overtime as possible. The business environment is hostile, where departments only interact to yell at each other. Outdated software and processes make what should be easy work, time-consuming. The volume of work that will be assigned to you will be too much. Quality suffers because everything is rushed out the door because there are SO many other jobs that need attention. You can theoretically have a lunch break. If you do leave for more than 20 minutes for lunch, however, you will come back to a stalled project, and tons of emails from people angry that something has gone wrong. That's why no ones does take lunch breaks.
