After being referred by an employee, I landed a screening interview where I was asked about my background, motivations and even had some behavioural questions in the middle.
The overall experience was bad mainly because the interviewer didn't turn on the camera and I couldn't form any type of Empathy. As a 1st interview I believe it's super important to create some kind of relationship with the interviewer so that the interviewed can adapt the pitch. The feedback given was always the same after each question and it demonstrated lack of interest since the beginning from the interviewer.
If this interviewer is the "cover" of the company, I'd seriously consider applying somewhere else.
