Pros
Interesting projects at times (for example, working on different drugs), but in the end you're essentially doing the same kind of work, same kind of analysis, same PPT presentations and with the same company (90% of the time). Pay is good considering the size of the firm. You get to work from home on Fridays, which is an added benefit if you have kids.
Cons
The first poster was a little harsh in the review, but I had experiences with each one of those issues. It's true new hires receive (or used to) no training. The idea was that smart people are hired so that they can navigate themselves and learn on the job. Sadly, I've seen people fired and other quit because of this line of thinking. Even top 5 consulting firms have training programs for MIT graduates. It's foolish not to have one at C1. The work ours are grueling, especially when traveling. You're expected to be in the office the same day you return from travel. Even when employees do interviews, you can see the work schedule taking its toll. When I interviewed, current employees spent little time actually explaining the cases to me and seemed rather miffed if I didn't understand a concept being asked. Clear favoritism from many angles. Analysts are certainly not in the inner circle with the MD. Even among consultants, there are clear favorites, which means either a) suck up to her more, or b)don't be a man. It wasn't surprising to see one person told that they wouldn't be allowed to take time off, but a different person be given the green light. It all boils down to the MD's view of you and your work, which is made all the more arbitrary considering the lack of her presence in the office. Take the job if you have nothing else, but chances are you won't be there that long. I would say at least 70% have not been there more than a year, with only one person who has been there over two years. Do yourself a favor, work at someplace established with clear guidelines and where you can at least get benefits common in the industry (paid cell phones, gym membership, etc.)
