Classic Technologies & Business Solutions interview questions

Utterly worst experience. First round is machine test. I cleared that, followed by 2 rounds of technical interviews. I also cleared that. Final round was taken by technical manager which was not an interview, it was kind of discussion. He asked me some kind of puzzles only. I was expecting the call from HR for the final HR round.But the HR sent me a feedback email that I didn't clear the interview process. I was totally shocked to hear this.Still I wondered why they allow me to attend final 4 rounds of interview including machine test, if they feels I'm not fit?

Phone Screen: The questions in this round will be related to your resume and skills, focused on understanding you as an applicant more than your technical proficiency. 2. Technical Interview: You can expect questions related to coding, algorithms, and machine learning. You will be assigned 1 or 2 problems to solve within a stipulated time. 3. On-site Interview: The final and most challenging round of the Amazon SQL Interview process is the on-site interview, also known as “The Loop.” There can be 3-5 rounds, where each round goes on for about 45 minutes and is extremely exhausting. The loop can be further broken down into 3 types of rounds: Coding round , Behavioral round, the Bar Raiser round.
