The interview was for advanced package modeling expert. HR was extremely unprofessional. She did not even update to me that they don't want to move ahead with my application until I sent her an email two days before the first schedule (re-scheduled due to interviewer unavailability the actual first time) interview asking her to update the job description attached to the meeting invite. She had attached the wrong job title and description, seemed like she got confused and could not understand the nuances for the job I had actually applied for. Such a disappointment and utter waste of time! If they don't want to interview all candidates that they selected before making a decision, why even select more than one?
