The flipside of the performance-oriented culture is that your professional development and success at the company is evaluated based on the impact you are making. This can mean you won't get a lot of recognition for working hard on something that doesn't drive impact, and that if you are in a junior role it may be hard to make a big impact in your first year or two. You have to be open to feedback and enjoy solving hard problems to do well there.
As a company in Silicon Valley where startups are continually raising tons of money from VCs and trying to dazzle with their innovative ideas, QuinStreet can feel a little stodgy. QuinStreet has historically been fairly quiet as a company, and has done virtually no PR or brand-building - which makes it a bit hard to understand from the outside. People who have been working in the digital advertising industry for a while will know QuinStreet, but it may not get much name-brand recognition outside of that.
