Both interviews were very unprofessional and disappointing. the first interview was about one hour on skills review and some irrelevant private and family-related questions, without describing the company and the position or salary range.
the second interview was a bit more specific after signing a confidential agreement on interview contents. However, the conservative interviewer (CEO) had a very basic knowledge of the scientific aspect of the work that I was asked to explain and it was hard to understand his points when it comes to science. I think he was just there to not being asked about the accuracy of the questions. He wanted me to be confident in my answers but personally, I can't say anything when the questions are not clearly and scientifically asked. Overall, the interviewer has not experienced leading a scientific interview.
