I wouldn't go so far as to say "Medtronic Sucks" across the board as an employer, but current day Medtronic definitely has some sucky aspects to it when compared with some of the pre-acquisition companies and the Medtronic of old.
I spent 5 years at an acquired company and 9 as part of Medtronic so I do speak from experience. I was not part of the sales force so my experience there was somewhat limited. I did support the sales force and operations among other things.
One good thing about Medtronic (any device or pharma company really) is you can develop a real sense of purpose in your job. It never bothered me working some crazy hours and being on-call 24x7 because the organizational mission was a matter of life vs death, disability, or pain. Medtronic also pays fairly well, salary and bonus wise.
Pre-acquisition and for some time afterward, it was a great place to work with a lot of really smart and highly motivated people to accomplish things which made a difference.
However, as growth slowed and the company restructured its upper management team, it was a steady downhill slide into being just another big corporate environment run by bean counters and empty suit executive has-beens from other companies outside of the device industry.
Nowadays, the pay is still decent, but motivation-wise, you may as well be working at Wal-Mart. There are still isolated cells of innovation scattered around the organization, but the star to douchebag ratio has swung way in favor of the douchebags.
HR, like HR of most big corporate organizations, is one of the worst performing departments. HROC at corporate is decent, but HR out at the business units are some of the least competent employees in the organization. It's very difficult to hire good talent, and equally difficult to kick out dead weight.
Due to all of the unethical and illegal behavior (e.g. surgeon kickbacks, the dark side of the device industry) the company is also now dominated by an army of lawyers and compliance people. If your surgeon sneezes, you had better not hand him a kleenex unless you file it on your T&E, where its cost will be aggregated and tracked. Yet you still read the stories of the crooked consulting agreements, hiring surgeon family members, even reps scoring coke for docs.
Internally, where many projects were historically focused on bringing good products to market, providing good support to field reps, etc. now many projects are focused on some internal nonsense which often means nothing to the core business. Upper management (now heavily slanted towards ass-kissers, yes men, outside-the-industry geezers and has-beens looking to supplement their income or retirement) will spend huge money to bring in outside consultants (snake oil salesmen with an army of inexperienced grunt workers) to launch some initiative which has nothing to do with the core business and ultimately fails with no accountability back to the sponsors. Then they'll try to whitewash it as a success to cover their own asses and dump it on the most convenient group of internal peons they can find. Note that I am describing current-day Medtronic, but I could be talking about almost any big corporate organization, where the leadership no longer understands the nuts and bolts of how to run the business, and instead they read the latest crap from Gartner etc. and try to recycle it into a big win for their resume and internal advancement path.
I will always look back on my time in the device industry with fondness and nostalgia, but I am very happy to have gotten out at an opportune time last year, and now working for a smaller organization that isn't wasting money on crap projects, or shipping jobs overseas at breakneck speed. For internal prospects, there are still cells of productivity in the organization, so hope you land in one of those. As for the sales force, hopefully having their unrealistic growth targets exposed as phony for multiple quarters (or years, as the case may be) will help you to get a more achievable sales plan in the future.
