An Insider's view of Quantcast

What are some social events your company does?

We're a tight-knit team that likes to socialize over regularly catered lunches, laid-back happy hours and stimulating offsites. Company-wide hack-a-thons give engineers the opportunity to collaborate globally. Whether it's puzzling through an escape room or sampling each other's dishes after a cooking class, we aim to keep events fun and inclusive.


Manager, Engineering

How do you make yourself accessible to the rest of the team?

I regularly meet with people one-on-one and in person, and solicit feedback on how I can get them the tools they need. I have been at Quantcast for 8+ years working on different parts of the business, and routinely give talks on what I am familiar with so that people know they can ask me about a variety of the different areas of the company.
