Pros
Friendly colleagues, nice offices, opportunity to learn about the minutia of commodities markets. I can speak only to the news side of Argus, but within news the hours are comfortable, the pace is consistent, the job security is good and you get to become an expert in whatever commodity is assigned as your beat.
Cons
If you're a journalist aspiring to be a reporter at a big newspaper, you might have the chance to get hired at Reuters or Bloomberg writing about commodities one day. But at Argus you'll mainly be asked to get price information about commodities and examine the most niche aspects of a given market. You won't be asked to write exciting stories of the sort you read in big newspapers. Argus generates its revenue from providing information about the prices of over-the-counter commodities contracts, not from stories that provide general information. If this is ok with you, then Argus is a great place, because it provides good job security and comfortable hours. If you want to climb through the ranks as a journalist though, then you'd best use your time at Argus to gain experience in commodities and then find a commodities reporting job at, say, Reuters, or instead go to journalism school and get an internship at a big news organization.
