Pros
The unique and laid-back culture lures new-hires in. It's a fun place to be, and many times the work can be exciting and engaging. Work-home balance is good, and it's easy to make friends to hang out with outside of work as well.
Cons
NI tries to hire the best and brightest, but pay is less than average, and the company tries to avoid the issue by saying it uses a 3rd party industry comparison to ensure salaries in line and bring up the "total package" argument as well as highly-discourages sharing your salary amount with anyone else. Health care isn't as good as it used to be years ago. Once you start achieving a higher rank it's still hard to feel valued or that your opinions matter. You spend more time arguing for resources you need to get your job done than what it would cost to just go buy what you need. Praise, bonuses, or any other positive encouragement is very infrequent. Lots of inefficiency and delay caused by consensus-driven decision making, and management changing their mind about where focus should be or changing their mind about critical decisions during the design process.
