DON’T APPLY THERE AND SAVE YOUR TIME! I have given the interview for a Ruby on Rails developer position, the first two rounds were technical and the third one was a hiring manager round. I cleared the first two rounds which were about Ruby on Rails concepts and nothing else, no DSA. In the third round, there were again technical questions from the hiring manager. Design a user messaging system with file and directory sharing like a cloud drive, design tables and necessary associations. I have discussed the problem statement, gathered the requirements and answered everything correctly all within interview timings. The interview was completed before the time so the interviewer said that Let's do some more questions and he asked some SQL queries which I also answered correctly. Then at the end, we discussed the roles and responsibilities that I would have and other things regarding culture. Everything went so good that I was expecting to receive an HR call for the offer but they rejected me via email. This is so unfair for me, I have given my time and efforts in these rounds and they rejected me with no reason. I was looking for opportunities to join and they were just time passing the whole time, why do you interview engineers if you are not willing to hire them?
