OMFYS interview questions

L1, Managerial, HR L1 is 30 min to 1 hour, Managerial is 30 min and then HR will call you if you got selected. And then offer letter will be issued

I was notified by my training center that there is a Interview scheduling for Omfys. Later i got mail from company side for Online Technical interview. I was unaware that other side, CEO of the company will take interview. No problem. He asks me self introduction, the skillset I pursue and asked "Have you completed any fullstack project by your own?". I said i worked on it with team team members. But trying to work on it by self. Suddenly he replies "Ok, then we cannot proceed with you, This is not a training center..." And he leave the meet. I was requesting him. But he didn't accept it. What to say now... At times, a company's reputation may suffer because of one person's error, despite its overall good performance.
