I had an interview for 30 mins with 2 people, but only 1 person attended and did the interview. It was like a screening call so it was about introduction, my current project, I did it pretty good because the interviewer gave positive feedback that there will be another round with their seniors and even mentioned their names but after that the recruiter didnt respond for the next and after 3 weeks I got a rejection mail didnt know why may be I didnt do well

The interviewer didn't open the camera and asked mostly about resume, stat, and brain teaser question. It's not that difficult but I didn't respond to the last brain teaser question
