National Payments Corporation Of India (NPCI)

Overall level of the interview was easy and focused on fundamental concepts. There were 2 technical rounds and a very brief HR round. The interviewers were very nice and friendly and even added a little humor while asking questions.

Worst experience, I've been co ordinating interviews as a recruiter from past 9 years now and this have been the worst candidate experience. Firstly the co ordinator Soniya took weeks to schedule the interview. Then I got a call to be available on the next day. I told her that I have my office but I will start office late ( as I didn't want to delay the interview again) even then the panel didn't join and delayed the interview by 30 mins. Then came the panel, I guess she's heading recruitment but she had no video on during the interview. She was in a no network zone , throughout the interview hardly 15 mins I was able to hear her . The co ordinator asked me if I was facing internet issues, I shared the network speed test report with them . If you are conducting an interview ensure you have the bandwidth and be respectful to each others time. Lastly the things they are expecting and the things they have in the JD hardly matches. Lastly she asked me a basic question about data engineering keyword and I was not even able to answer that well though I have established the data engineering team for a client . I was so bothered by the constant network issue that this experience was totally a nightmare. Even basic things about who all are in your family - had to repeat twice and I'm 100%sure she didn't hear coz the network was really bad. Lastly I was not shortlisted and was not informed, I pinged the co ordinator multiple times and the response - "not shortlisted " no feedback, no reason nothing!! Feedback for you - Please have a professional setup during interview process, Also AI won't help your org if you don't have human approach or EI .. Respect and value others time too.

First of all Teams interview with reporting manager, then technical assessment, Psychometric assessment and lastly final in person interview round with the Head Of Dept. Then offer negotiations and documents to submit.

The interviewer asked me to introduce myself and elaborate on my academic journey. I shared insights into my educational background, interests, and experiences, focusing on how they shaped my skills and aspirations. The technical round began with a discussion about the Machine Learning project I had mentioned in my resume. The interviewer asked detailed questions about the project's implementation, the algorithms I used. They also asked conceptual questions on ML, which I was able to answer confidently. After this, the discussion shifted to my full-stack project, where I explained its functionality, how it worked, and some specific implementation details. The interviewer then tested my knowledge of core subjects like DBMS and Data Structures. They asked me to explain the different types of joins in DBMS, the purpose of the HAVING clause, and to write a query using the HAVING and GROUP BY clauses. In Data Structures, they asked about real-life applications of stacks and queues, followed by questions about a project in my resume that involved a Trie data structure. This included explaining how a Trie works and its use cases. The technical round concluded with a coding problem where I was asked to reverse a string. I explained three different approaches to solve the problem, highlighting their time and space complexities. The interviewer asked me to write the code for one of the approaches, which I did successfully.
