I worked at Sun Microsystems full-time (More than 8 years)
Great company culture, collegial atmosphere, intelligent coworkers and smart, effective managers.
In the final years, the top management lost their way and focused too hard on giving away the company crown jewels -- Solaris OS code -- for free.
Advice to Management
Don't give away your patented technology for free!
I applied online. The process took 2+ weeks. I interviewed at Sun Microsystems (Aurora, CO) in March 2016.
Had phone screen two weeks after applying online. Follow-up one week later. Another phone interview happened 5 days after second phone interview. Finally had a live interview after 3 weeks. Seems like a slow process. Actual interview lasted 2 hours.
