HashedIn by Deloitte interview questions

My interview was scheduled at 9 AM but no one was there when I reached. The HR finally appeared around 10:15 AM and my 1st round began with a technical interviewer. The round was based on ReactJS and the basics of JS. I had to wait for 30 minutes before the 2nd round began. It was focused on DS and Algorithms. I cracked all the questions and went ahead to the 3rd round. Again they made me wait for like half an hour. 3rd round was fitment round. It went well and then the HR came and told me that your feedback was good and we can discuss the salary on call. I was okay with that and left for the day. HR never replied after that. Even after mailing her, she didn't reply. Quite unprofessional! I wasted my entire day for this interview and these guys don't bother to reply.

There was a coding round first, which was on pen and paper. It was a written test with 3 coding questions . You have to do atleast 1-2 to get selected. Then there are three technical interviews and then HR. They select very few and best ones. So focus on problem solving and data structures with optimization.
