Vantaggi
If your first priority is to put some money in the bank then, by all means, climb aboard. You will often make your quota+bonus, since everyone around you focuses on sales before all else, which helps the bottom line on a quarter-to-quarter basis. There is plenty of work to do!
Svantaggi
You are always living on a quarter-to-quarter basis. The highest level of effort you can bring to the job will often be seen as "barely adequate" by your supervisor. There is no such thing as management feedback for the purpose of personal development. Most managers completely ignore the official HR performance review process. Praise consists of back-handed compliments, such as "you did good this time, but you should have done much better." The overall attitude is "we will never be good enough." This pervasive culture of negativity is probably a holdover from the company's poor performance over the last decade (even though the company is doing quite well now). The deeper problem is that success is not its own reward at PTC. There is no reveling in your accomplishments here. You can never do enough. This is not the place to build a career AND live a life you love... unless you don't care for life outside of work.
