About me- Former engineering lead of user growth at Quora- Led teams at Ooyala and worked on Google search- Writing a book on how to be an effective software engineer
Growing the team at Quora- Helped grow company from 12 to almost 70- Started mentoring & onboarding programs for new engineers- Developed interview guidelines and training sessions
Interviewed 500+ people- Many engineers from strong engineering companies- Google, Facebook, Palantir, Amazon, Dropbox, Apple, etc.
“A good culture attracts and keeps the kind of people that helps your company become successful.”

What is one thing you liked and one thing you disliked about the engineering culture at X?
10 elements of a great engineering culture
01 Optimize for iteration speed
Continuous DeploymentQuora released code 40-50 times a day.
Developer productivity tools- Continuous deployment- Continuous integration testing- Faster compile and build times- Incremental reloads for web servers
Avoid organizational bottlenecks- Google's weekly search UI review- Empower team leads to make decisions- Define clear channels for quick feedback
"Commit, explode, recover. "-- Bill Walsh, former 49ers coach

02 Develop high code quality through code reviews
Higher code quality lets you iterate faster- easier to reason about code- quicker to modify- less susceptible to bugs
Modelling is important

03 Push relentlessly toward automation
Automation is extremely high-leverage- Invest in automated testing.- Automatically handle failures, restart services.- Automatically scale up services at peak traffic.
"Optimize for minimal operational burden."-- Mike KriegerInstagram co-founder
Grew Instagram to over 40M users with 13-person team
04 Build the right software abstractions
"Pick the right ones, and programming will flow naturally from design... Pick the wrong ones, and ... even the simplest of changes will be hard to make."
-- MIT Professor Daniel Jackson, Software Abstractions
Compounding benefits of abstractionsGoogle - MapReduce, Bigtable, Protocol BuffersFacebook - Thrift, HiveQuora - Webnode, Livenode
05 Build an open and respectful work environment
“Writing software is a team sport.”-- Brian Fitzpatrick andBen Collins-Sussman, Team Geek
06 Build shared ownership of code

07 Embrace failure and accountability

08 Allot 20% time
Promote experimentation- Google - 20% time- Ooyala - hackathons- Quora - offroad weeks- Facebook, Atlassian, Dropbox

09 Build a culture of continuous improvement
Grow reusable knowledge- Invest in onboarding and mentoring- Encourage tech talks and document design discussions- Write codelabs
10 Make hiring a priority
"I figured Google would be better [than AltaVista] because I knew more of the people there, and they seemed like they were more technically savvy."-- Jeff Dean, Google Fellow, in Steven Levy's In the Plex
