    I have been working at Cornerstone Environmental full-time (More than 3 years)


    Competitive salary and benefits (with decent raises and bonuses); unlimited room for advancement for hard workers who embrace new and challenging opportunities; the sense of being part of a small, intimate company despite being a Tetra Tech company; managers that doesn't micromanage if you're doing your job well; good office camaraderie; general appreciation of marketing group efforts; and managed by some of the most respected professionals in the solid waste industry.


    I wish the Portland office had more people so there was more personal stimulation, but we're growing, so hopefully that's a temporary issue.

    Advice to Management

    Don't let Cornerstone get lost in Tetra Tech -- so far, so good, so keep it up!

    Average Interview


    I applied online. The process took 3+ months. I interviewed at Cornerstone Environmental in February 2015.


    I applied online, just to a random drop box, no cover letter. Was contacted about a month later to "discuss the opportunity" by phone. I was a little irritated when I received the call because I didn't realize that "discuss the opportunity" meant a phone interview. None the less, I did the phone interview, which I thought didn't go too bad having to think on my feet. They said they would be in contact in about a week or so. I didn't hear back within the week, so I followed up. They said that the senior hiring manager hadn't yet looked at it, and that they would be in contact once that person did. I still didn't hear back for two weeks, so I followed up again. This time, I was told that the position was officially on hold, and that when it came off hold, I would be contacted. None the less, I haven't heard back for about a month and a half, so I'm assuming that I didn't get the position. I think that it was unprofessional to leave me tagging along for so long, as I'm working on my job search and it was my first phone interview ever. I just wish that they had politely declined me the position or at least let me know if they had chosen another candidate. In my opinion it doesn't matter how big or small your company is, if a person is interviewed in person or on the phone, I think that person deserves a response from the company regardless if they are offered a position or not. It's rude and unprofessional to be interviewed and never contacted again, especially after three follow ups to show interest in the position. Very unprofessional interview process.
