SUNRISE FUTURES Quantitative Analyst interview questions

I applied online and got an email from recruiter after a week scheduling for two tech interviews: the second will hold only if you pass the first interview. I thought my two interviews went smoothly but got an rejection email from them the next week. I was a little disappointed because I felt I deserved at least personalized email after two interviews, but got a template rejection email without feedback on the interviews. No response when I tried to get some feedback.
