Came on site to interview for a systems engineer position. Most of the interviews were standard questions and interviewers were nice. Had a system design interview however, with a senior engineer shadowing a new grad. The overall tone of the senior engineer was quite condescending as he asked his questions. At more than one point, I turned around and caught them both smirking to each other and mocking my answers behind my back. Made me feel super uncomfortable and out of place. Would not want to work with people like this.
