DehazeLabs interview questions

I got an email for conducting round 1 which is on Google meet. Online coding round by sharing screen. It is worst experience ever. The interviewer first asked about my introduction and then he said after checking your resume i feel you are too young for this role i said I'm 7th sem. But he didn't want to listen me he said you can contact with HR. If i am too young for this role then why do you shortlisted me????
