I first had three behavioral interviews. The questions were nearly the same... all about how I respond to ambiguous situations when you do not have the exact data that you are looking for. Then, there were a few behavorials about working on a team. I felt that all of the interviewers could have hosted me for one or two Zoom calls to be mindful of my time as well (no need to ask me the same questions on three separate 30-minute Zoom calls...) Then, I was asked to come in person to do a presentation. I had 48 hours to analyze data and create a presentation. Needless to say, I was very excited about the position, so I spent a lot of time on the assignment. I did feel that this was a big ask for someone who has a full job (e.g., they do not know if I have night work calls, etc. nor did they care to ask ---> just told you that you have 48 hours). Perhaps providing a week would have been fairer or just simplifying the assignment. Creating an impactful presentation alone/rehearsing could take two days... Once I went to present in person, I felt that the interviewers wanted to be anywhere else but with me. I was asked to email my presentation in advance. I am thinking that perhaps they were not impressed by my analysis and already ruled me off. I would have been so appreciative if they just decided to tell me to not come in if that was the case. Needless to say, I missed work and went in person to present. The team was cold and were talking about other meetings etc. when they were with me. Normally in interviews, the interviewers try to make small talk and engage with you, but I felt invisible. It was an extremely awkward experience. When I then thanked them for their time, they did not share next steps nor respond to thank you notes (I understand that not all interviewers respond.) I then receive a generic rejection letter from HR telling me that they have so many qualified candidates. I was just a bit surprised by the entire process. If someone invests a lot of time creating a presentation, I would have at least expected HR to nicely call to reject me after spending +20 hours in the process. More so, it wouldn't have hurt the team to at least be kind and respectful to me when interviewing, even if they thought that I did not do a good job. I found the team to be very unprofessional. Overall, I am not one to write Glassdoor reviews, but I felt very uncomfortable after my experience and want to warn other applicants beforehand if they think this process is worth their time.
