Last 3 March 2016, Fortune released its annual survey of the 100 best companies to work for in the U.S., and Google (now known as Alphabet) topped the list for the seventh time.

All told, California was represented by 20 companies, including Genentech (11th), a biotechnology and pharmaceutical firm in South San Francisco.

Two-thirds of the results were determined by random surveys distributed to employees of participating companies. Respondents are asked about management's credibility, overall job satisfaction and camaraderie.

The other third is based on pay, benefits, hiring practices, training and diversity.

Google was lauded for its famously generous perks, which include healthcare for part-timers, on-site childcare and paid time off for volunteer work.

"The perks are phenomenal," an employee told Fortune. "From three prepared organic meals a day to unlimited snacks, artisan coffee and tea to free personal fitness classes, health clinics, on-site oil changes, haircuts, spa truck, bike-repair truck, nap pods, free on-site laundry rooms and subsidized wash and fold. The list is endless."
