Snaptrude interview questions

I had 5 rounds of interview - Introductory call - Assignment - Tech round 1 - Tech round 2 - Leadership round It was smooth and the rounds were scheduled quickly

Totally bad experience. It was an Oncampus opportunity, cleared the OA,then gave the 1st round of interview.In 1st round, I got a DSA question and linear algebra questions, solved successfully, after that I got an assignment. Build the assignment successfully and implement all the necessary and bonus feature. But after that interviewer ghost me and after some days, I got rejection mail. The Hr told me that, I lack technical skills in interview while I got the positive feedback on Round 1 and was hoping for the 2nd round. I literally don't understand, what are they guys looking for a fresher they just give a random Babylon.js project, the techstack I had never worked before... But I tried my best to learn the techstack in 1-2 days and submitted the assignment on time. Really worse experience...
