It was a general purpose call, including some introduction, talking about the company, general HR questions followed by a few technical discussion & explaining my background for the role. The 30 min call went pretty well, and the interviewer (the CEO) mentioned that it was just an introductory call, and it went pretty well as she was genuinely interested in my research work and ideas on their current projects. She went on to thoroughly describe the actual selection process that will soon follow and that I should start preparing for the same. However, they ghosted me after that and I never heard back from them( at the time of writing this it has been 3+ weeks). It was really hypocritical l, considering the CEO spends half her time on LinkedIn and is quite active. She posts a lot about malpractises in the industry & technical hiring processes, the bias and sexism. However when it came to showing some common professional courtsey she chose not to write a short message which takes no time at all.
