The professionals that filled the various roles in the office ranged from excellent at their jobs to totally incompetent. Some flourished in this world while others didn't last long. However, it seems as though everyone had at least a few good moments while even the most successful among them were capable of mistakes.

As the senior copywriter at the firm, Freddy Rumsen had a very important role even if it wasn't highlighted all that much.

Though Ken Cosgrove is introduced as one of the men in the early seasons of the show, his attitude toward his job was much different than his colleagues. Despite his writing talent, Ken took a very easygoing approach to office politics which allowed him to get promotions and raises over his frustrated co-workers.

Eventually, Ken's easygoing nature gets eaten away. Though he doesn't enjoy his job and has plans to become a writer full-time, he abandons these plans when he is fired from the firm. He s another company and another job he dislikes purely out of spite.

Roger: Getting Chevrolet / Sabotaging Honda Deal

Despite being one of the owners of the partners of the firm, Roger Sterling is mostly seen as a hard-drinking playboy who jokes around a lot. He was never really seen as someone who was necessary to the success of the firm, but he proved himself by acquiring Chevrolet as a client, something the firm had been hoping to do for a while.

Ironically, Roger's lowest point as a professional was when he sabotaged the chances of acquiring another car company. Roger storms into a meeting with Honda and begins insulting the clients with racist remarks, ending any potential business.

However, she eventually realizes in order to be taken seriously as a partner, she needs to leave that work behind.

While Joan proves herself to be one of the most ambitious characters on the show, she is quite insulting of another woman with dreams of escaping stereotypical roles. Joan is quite mean when Peggy expresses an interest in writing and she looks quite foolish when Peggy proves her talent.

Pete: The Nixon Campaign / Blackmailing Don

Pete Campbell doesn't have the same creative mind as some of the others in the firm, but he does have the occasional good business idea. When looking to provide ads for the Nixon campaign, Pete comes up with the brilliant idea to simply fill the airwaves with commercials for their clients, thus leaving no room for Kennedy ads.

In the first episode of the series, Peggy comes into the office as the timid new secretary. But before long, she begins displaying skill as a writer. Even though others dismiss her at first, she has the confidence to demand more work and grow as a professional.

Peggy has proven herself to be so preoccupied with work that she lets her relationships fall apart. It shouldn't be surprising that she eventually pursued a relationship with her married boss, Ted. But predictably, a work romance became too complicated and got in the way of Peggy's career.

Don: Promoting Peggy / The Hershey Pitch

Don Draper continuously proves himself to be a brilliant an despite his other shortcomings. However, when he saw talent beyond his own, that's when he really started to shine. He promoted Peggy as a writer and the two ended up being an incredible team together.

Don is especially talented in pitch meetings where he regularly gets clients to fall in love with the ideas he describes. This is the case when he pitches to Hershey, but after they accept the idea, Don backtracks and opens up about his real childhood, which completely ruins the meeting.
