The first 3 interviews were very easy: I was encouraged, complimented, and supported. But it's obvious to me now that they were simply love bombing me, and has 0 interest in hiring me. For my 4th interview, I was instructed to create a presentation of what I've been doing for work for the past 4.5 years, so I did precisely this. I was invited to lunch because they "wanted to get to know me first", but when I showed up, they skipped this completely... The CEO told me that he didn't want to see my presentation because he didn't have time. To sum myself up in 2 minutes because he doesn't know what I've been doing all these years, and thinks that I don't have any real work experience. After he left, the girls kept talking over my presentation, laughing at me, and making rude/sarcastic remarks. Only one person asked me questions, but she's the only person with a real science background. So I presume the rest of the people I encountered have an IQ so low that they had no idea what I was saying. Worst interview ever.
