Pros
1. Its belief and mission in promoting sustainability. I personally believe that this is an important direction the world needs to take and I am glad that Ramboll is a strong believer in this as well. 2. It's a prestigious brand, which adds to your personal resume.
Kontras
I've worked in the Singapore office and hence will be writing from that perspective. 1. It's too big as a firm. While the vision is clear, the strategy on how to get there and how to go to market can be quite lacking. Report lines can be confusing and processes can be bureaucratic. 2. It's fairly conservative in risk appetite. This means that they're not willing to try new things. Departments are also very much down to the bottom line - not that it's not important, but sometimes the firm seems focused on short term P&L and lack the gumption to proceed in a certain business trajectory. 3. It's very European-centric. This means that offices and colleagues not in Europe can be seen as "second class" compared to the European colleagues. At times Europe may want to enter your market to "compete" for the project, which makes it competitive. This may mean that you may not feel supported by HQ if you're not in Europe. 4. Related to 3, they do not quite understand non-European business cultures and markets, and tend to make decisions through European lenses. This can make it difficult to pursue opportunities if you need support from Europe on specific projects, as they may take too long to decide or may decline participating. 5. Ironically, each office functions quite independently with little opportunity to work together and cross share, even between offices within the same business units. 6. Related to 5, Singapore's perks are really poor compared to Denmark. Pay isn't great, leave benefits are minimum and the location of the office is inaccessible.
