Interviewed with 5 different people from the time at separate times, so it's not technically a panel or group interview. If accepted, you will be sent a writing exam and they rate you on your creativity and encourage you to have fun with it. My writing exam was to write a press release on a new invention and it was definitely easy to finish. I was offered a position the next day after completing the exam- they seemed very on top of things. There wasn't too much to see about the work culture since you are in a conference room that's in the front of the office, but when you hear people laughing in the background, it's generally a good sign that everyone gets along. You can tell by what the employees are wearing that the environment - like any other PR agency - is very relaxed. The decor is also very cute and vibrant as red is Ogilvy's color. Please note: do not let the office attire stop you from wearing interview-appropriate attire. There was no lag time; they were great at moving the interview process along at the before, during and after the interview.
