    It was quite good. Questions asked were mostly related to DSA. The interviewer asked me what topics i am comfortable with. The interviewer then started questioning about my projects .

    Very bad experience. The guy who took the interview didn't have much knowledge. It was shocking to know that someone working at Paytm payments bank didn't knew about PCI compliance and credit card tokenization. He asked few questions on algorithm and DS. In some questions the guy was not convinced even after giving correct answer. It seems the guy only knew 1 answer and was expecting me to say that answer only even though my solution was quite optimized in terms of time complexity. Answered most other questions correctly including the system design. Finally when HR told that I didn't clear it, I was shocked. I think overall it went well.

    @HR Please only allow those people to take interview who have good amount of technical knowledge. The guy himself didn't knew a lot of things one should know in IT field.

     But I would like to appreciate the HR mam for being polite and she gave clear feedback immediately even though it was negative. No hard feelings.

    First round was a F2F discussion at the Noida office. DS questions along with Java concepts were asked. The second round was mix of design questions and DS round. The second interviewer seemed he had never taken an interview before. He was not clear what he wanted to ask in design question round. He came without pen and paper and asked me to code/design on table instead!! He was taking calls in between the interview and also was expressing himself in words like 'It's not fun".He seemed very crude. Companies should train such people in interview taking etiquettes. He kept on saying he has less time and if i can speed up. Worst Interview Experience ever !!!!!

    J'ai postulé via un recruteur. Le processus a pris 1 jour. J'ai passé un entretien à Paytm (Noida (Inde)) en février 2019.

    Entretien

    1st round was coding test on Mettl with 1 hour time limit. It had 2 questions. I cleared the first round and waited for 2 hours for the second round during which they served the candidates snacks and coffee which was a great gesture. Round 2 was F2F in which I was asked about my project and a few DS/Algo questions. I couldn't answer all of them. The HR let me know that my feedback wasn't positive and I was done.
