Mostly behavioral questions. Also questions related to collaboration. Made it to the the 4th round interview which is the presentation part of the interview process. It appears that there is a strong emphasis placed on presentation which is the 4th and final interview in the interview process. Was informed almost immediately by HR recruiter that my presentation was why I did not receive an offer. However, I believe that a decision may have been made by the hiring manager prior to the presentation. I would say that candidates should be informed after the 3rd interview if they truly are a final candidate for the position. Do not let candidates prep for the 4th and final interview, which involves the presentation, knowing that a decision has already been made to move forward with another candidate. There is much effort and time involved in preparation for this final stage of the interview process. Let's not waste each other's time.
