I experienced probably the worst interview in my career. I was initially contacted by the recruiter who set up a phone screen. Later, I was setup for a phone interview with the hiring manager. The phone interview indicated that it went very well. At the end of the phone interview the hiring manager was delighted and even said that they wanted me to come for a full onsite interview to meet the team and there will be a case that I needed to present. I was given the case interview couple of days before the interview. It was a vague and unclear case, but I made what I can with it. I went onsite met the hiring manager and three other team members in panel presentation/interview that was to be followed by more 1:1 interviews. I presented for 45 minutes. Unfortunately, what followed in these 45 minutes what will make me not buy or even interact with anything Intuit during my lifetime. The interviewers were unfortunately terribly condescending to the point where they showed no interest by looking over their phones, opening their laptops and even laughing inappropriately at certain points in my presentation. I clearly stated at the beginning the assumptions I made about the case and how I went upon doing the analysis work. Apparently, they did not care about what analysis to be done and just wanted what they perceived was "clear" from the case. After 45 minutes, they went outside for 5 minutes to what the manager told me a team "huddle". I was left in the room waiting. Then, the manager comes back in with just one of the other team members, who came in to take their laptop and told me that "They have very important work that came up and cannot finish the interview". Then, it was just me left in the room with the hiring manager who told me very abundantly the interview is actually over and will not be moving forward. The manager gave a very short reasoning why and that my three days of work on their case was not what they were looking for. I told them the case was really unclear and the manager reluctantly agreed with me. I was then escorted out and shown the door by the manager.. What a terrible way to conduct interviews. It was very emotionally draining to prepare for a full onsite interview for days, present for 45 minutes and then have the scheduled interview be cut short and shown the door by what I thought was reputable company. If you have already setup the time for the interview and made room for it then make due to your promised schedule and continue the interview to see what other strong points the candidate may have or even to educate the candidate and leave a strong positive impression. Unfortunately, the interviewer bias played a big role and really showed on them when I was presenting. The emotions that people go through during interviews are one of the toughest things people experience. I have never experienced a company cutting short a scheduled full onsite interview before after the interviewers have made the time for it in their schedules, nor the clearly shown condescending behavior towards a candidate during the presentation.
