The HM failed to introduce herself, the job, or what they were looking for. She seemed "annoyed" from the start of the interview. I ignored her attitude and answered all of her questions. I certainly didn't perceive any issues in providing answers (I was confident, and not at a loss), although some of her questions, frankly, indicated she didn't have a firm command of certain concepts regarding HPC telemetry. She terminated the interview a little early after I got to ask one single question. She seemed unwilling/unable to provide even basic polite interactivity (open or close). I was not impressed, and certainly wouldn't want to work for a person like this, even if offered the job.
