Wow, where to start! Blue Nile is a company that after 20+ years is still in "start-up mode" and leadership shows no intention of graduating up. Blue Nile may have been a pioneer in jewelry and engagement ring e-commerce, but with it's dated selection and lack of appetite for technology and innovation, I wouldn't be surprised if Blue Nile is no longer around in 2-3 years. That's just the business model; the company is in stasis.
As far as working at Blue Nile, the turnover is so high, handfuls of employees leave by the week (alarming!) In addition, the new CEO seems to be "cleaning house" and replacing veteran leaders who have been with the company since the beginning with sycophants from his previous companies. The last thing Blue Nile needs is a bunch of old white dudes at the top. That said, diversity within the lower ranks (middle management and downwards) is adequate at best. There also doesn't seem to be a path for growth or upward mobility. Working here has been so uninspiring - there are no guiding principles (other than the ubiquitous "customer obsession") and no transparency or unifying message on strategy, metrics, outlook, purpose, etc.
On the subject of uninspiring and people, there's no hiring bar and the salary budgets are low, which makes it super difficult to recruit solid talent (the smart ones just go to Amazon, Facebook, Expedia or any of the tech companies that offer more competitive pay). You truly get what you pay for - people that just don't care and/or don't get it. As a result, it's really hard to get things done.
If you are at the end of your career, are apathetic, agnostic about money or growth, and just want to skate by working a dull 9-5 until retirement - then Blue Nile is for you!
