    Easy Interview


    I applied online. The process took 4+ weeks. I interviewed at Integral Ad Science.


    Applied online, got an email with practice assessments. Next was a phone interview with the recruiter, next step was a talk with a hiring manager, next step was video interviews with multiple employees and the recruiter, then the final update. The interview process was VERY bland. Questions read off a sheet of paper that had nothing to do with the company or what they do, just about your personal life and "times you handled conflicts." The video interviews weren't any better. One of the employees admitted he was reading off a sheet that they gave him. Again, nothing about the actual company.
