Got a very short (~5 mins) phone screen from hiring manager 2 months after online application, asked about general technical background and CAD experience, which is a bit misleading for every mechanical engineer should be proficient with CAD. Received an invitation for an onsite interview 4 weeks after initial phone screen. Interviewed 4 engineering managers, 1 HR manager and 1 Director of engineering during onsite, each one last about one hour. One of the engineering manager was the one did the initial phone screen, each manager went through resume and asked technical skills related to their job if they are interested in hiring, one of them was first time to my resume. The HR manager did the standard behavior questions. The director of engineering did not dig deep into technical staff, more onto engineering management. Most of the questions were high quality, each engineering manager has own strong technical aspect. The director of engineering do not have experience on the specific area subordinates working on before he came to tenneco, the rest of people do not know much of the stories outside of tenneco.
