You will learn to work under stress, thrown under the bus by the upper management. When is the deadline you might ask, it is whatever the upper management promised the client in the meeting, in the end it needs to be presented by the upper management, so check the upper management for the font.
Designers are considered puppets to impress the upper management, those that choose not to be part of the show are simply let go. People are considered heroes for pulling all nighters. If you have a family stay away! Most designers live across the street as roommates and complete projects at odd hours, they treat the office like an architecture studio my teammate clocked in 94 hours one week (3 all nighters in a row!)
This place hires and fires haphazardly for ex: they hired 2 in February, laid off 3, hired 6 in March laid off 32, due to a project ending, while hiring 7 and told the latest employee that we are growing. If you windup joining the office ask around how long everyone has been there, you will find no one stay past 3 years. They select a few that tenure for the reputation of the firm. The clients are shown a "good time." While those 32 employees are being laid off the Design Director ran a personal errand in the company's car to avoid, "stressed" employees.
