First Interview is via Hireview, web services. I felt very awkward answering the questions this way but none the less I still received a call for in person interview. The interview went well, and they also make you take a test that covers chemistry and geometry and a wrriting sample. Then I got called for a second interview and I thought that went well but no call back. After a week I followed up to see if they had hired anyone and I never received a response from HR which was very unprofessional. I dont know if they just like to interview people here or what the deal is but I see that they keep posting the same positions over and over.
