3 separate interviews, including having to create a presentation for the final one. First two are are no big deal typical conversational background type of interviews could be combined into one. Last one is a bit different but could be different for those not great In “testing” environments. It’s also a little bit disappointing to get a generic denial after being asked to put in that type of work for a potential job. When asking that much of a candidate, give valuable feedback if not moving forward.
