Was asked to deliver a presentation/PD that I had done professionally but the interviewers were not clear in the type of presentation that they wanted. One interviewer did not like that I shared a slide deck that I developed for/with another client while the other said that the point was really just to get a sense of Pd style. When I tried to explain that I too had assumed that my Pd presentation was only being used for interview/style purposes and that yes I would of course develop it differently/edit it if giving it publicly to a new audience, I thought that I observed the critical interviewer making faces/biting her lip/retreating in her seat. Felt angry about the way I was treated in the interview and of course I did not get an offer even though my interactions with others in the company had been positive up until this point. My advice to the company would be to be clear in their expectations of candidates in terms of what they want presented and to also be clear internally on what they are looking for in a candidate/the desired outcomes for an interview process prior to coming to the interview table. I also wonder how the company deals with effects of interviewer bias - are interviewers allowed to form individual impressions of candidates prior to discussing as a whole? Or do dominant personalities hold the interview process hostage - pro or con? While having more people/staff involved in hiring processes is nice for inclusivity, what training is provided to hiring panels composed of staff at different levels of seniority? Experience in hiring? All in all a very frustrating experience.
