I worked at Covington & Burling full-time (More than 3 years)
Many excellent partners who care about teaching and mentoring associates. Good partners far outweigh the ones to avoid. High quality of work in many practice groups. Generally there is respect for personal lives. Highly respected firm in DC.
The pace of the work can be unrelenting and the hours long. Firm has become extremely large and impersonal. Has a culturally uptight and old fashioned reputation, which is largely true. Some practice groups offer far greater professional growth opportunities than others.
It was one quick interview, and then I received the job. I was supposed to have about 3 interviews but it was cut short by internal strife. Eventually the correct management decided I was the right fit.
