Pros
If you are looking for global experience in a big corporate conglomerate, then this is the place for you. This company does not think in terms of domestic markets only, rather, their business model and processes are built around global needs, which is exciting. For the most part, senior management does a great job buying companies with products that enhance its portfolio, focusing on number one or two market share. Salary and benefits are at the top of the scale if you are proactive in proving your worth. Senior management also does a good job at recognizing above and beyond efforts.
Cons
If you happen to be in a division or business under the Covidien umbrella and are struggling getting control of systemic quality problems, your days are numbered. They are quick to sell under-performing and/or sub-quality mired product lines rather than invest the effort to fix systemically. Additionally, they have a perpetual cycle of hiring and laying-off resources as the ebb and flow of quarterly/annual numbers change. Some business/divisions are still reeling from the TYCO days and haven't launched new products, some as long as 15 years! Lastly, depending on your position, be prepared to be pulled into due diligence and/or acquisition projects at the drop of a hat as they buy companies. AND, you are expected to still maintain/attain your normal business objectives on top of the extra work, which parlays into long hours.
