Susquehanna International Group Trading Operations Analyst interview questions

Extremely disappointing, and somewhat unprofessional interview process. I applied for the role last year(2017) and was interviewed in December 2017. Prior to the interview, I informed the recruiter that my knowledge of trading was limited, especially given that I was coming from an IT background. The recruiter assured me that the interview was predominantly competency based and that they were looking for people from all backgrounds, regardless of their knowledge of trading. This was not reflected in the interview. The interview lasted around 1.5hrs and was conducted with two non-HR employees of SIG. The majority of everything I was asked and what was discussed in the interview related to trading. My two interviewers could tell from an early stage that my knowledge of trading was limited however, they proceeded to ask me trading related question, increasing the complexity of what they asked as the interview progressed while they sat back and watched me struggle. Typically interviewers do their best to put you at ease. For a nervous student interviewing for his first job, it seemed as if these two interviewers were doing their best to make me feel uncomfortable and completely out of my depth. To add to this negative experience, nearly 8 months after interviewing, no one from the company has contacted me yet to inform me, as to what I can guess, that I did not get the job.
