Showed up early for an in-person interview but somehow the interview started later than planned, despite there being nothing going on in the office. One interviewer was clearly disgruntled with my presence and did nothing to hide it. Both interviewers seemed disappointed in my lack of experience, despite the position being for a internship. They also failed to disclose in the job posting that the position was part-time progressing to full-time. The job post explicitly said full-time. They also sprung it upon me that the job required me to be on production sites every day, wearing a hard hat. The questions themselves were fine, but the demeanor of both interviewers made me very uncomfortable.
