The lack of diversity in tech goes deeper than just the HR department. As was highlighted in the Ellen Pao gender discrimination trial, company culture is also key to keeping and encouraging a diverse workforce. Google is offering more internal training and workshops on unconscious bias, and employees can use part of their time to work on diversity initiatives. It's also looking at the root of the problem, expanding computer science education for kids and pushing to get under-served communities online. The company still has a lot of work to do. According to the diversity report it released last year, only 17% of its tech workers are female, 1% of its tech workforce is black and 2% are Hispanic. In the blog post, Lee said Google plans to release 2015 diversity numbers soon. In March, Google executive Eric Schmidt was called out during a panel on diversity at SXSW for repeatedly interrupting Megan Smith, the chief technology officer of the U.S. and a former Googler.
