Technology Innovation Institute Robotics Engineer interview questions

I got approached by a headhunter and was asked if I want to apply to a Robotics Engineer possition or a Software Dev position. Because of how it was advertised, I chose the Robotics Engineer possition. Sent in my resume and some other documents, had an interview with the headhunter, then booked an interview with TII. At the TII interview, I was interviewed for a Field Test Engineer role which was very odd. After consulting the headhunter I was told that TII felt that I was more suitable for that role and without consulting me or even informing me beforehand of what the interview is going to be about, they interviewed me for that role. Even during the interview, they didn't disclose to me what the possition I am interviewing for is. It was after an hour of wasting my time, that I found out trough questioning the interviewer, that the possition was changed by them. Most shamles company I have encountered so far. Complete scammers.
