Inventia Life Science interview questions

I went through a standard screening process along with several 45 minute long interviews. I was also asked to give an extensive presentation on digital marketing strategy. The interviews were straightforward enough, but in retrospect the presentation felt a lot like the company was using it as a way to receive free consulting work. There was lots of preparation work on my end and very little in the way of meaningful questions/response on the Inventia side. The most frustrating part about engaging with this company was their lack of decisiveness and communication following the series of interviews. I repeatedly asked for updates over the course of roughly three weeks following the interview but receiving ambiguous responses each time. Ultimately I was rejected for the role after being strung along for several weeks. In hindsight, this was a blessing as I am glad I did not join an organization with these sorts of communication deficiencies and behaviors exhibited towards job seekers.

Applied and interviewed with HR, the call sounded like it went well and they said they would get back with me my a specific date and then I never heard from them again. So basically got ghosted with no communication from them. The job is no longer listed on their site so why not just send a rejection.
