Odd, many questions not related to job applied. Interviewer not knowledgeable about opportunity yet wants to interview applicant just to influence outcome of project negatively or put applicant on notice not to accept job offer since interviewer does not want project to succeed. The vacancy is a couple of months old. This may signify that the salary and benefits package are inadequate, or the company simply examined the market and didn’t really need new employees. Anyway, it’s better to not waste your time. There are too many newcomers in a company, and the employees look like they were hired just yesterday. It’s not a new company, consider this a bad sign. High staff turnover often means poor working conditions.
