Punon Technologies interview questions

First Round was with HR, where HR asked a few details like last date of working, salary expectation, and projects and told if sortlishted let me know. I selected for the next round--- The second round was a telephonic interview, where one of their seniors asked technical questions about Node.js backend technologies, database optimisation techniques and so on. I cleared the second round and was selected for the third round In the third round, mainly a machine coding round - where asked to create a backend application from scratch, including database connection, and create a REST apis where need to save employee details along with all field validations. I asked for the time; the interviewer told me I have to build within 20 mins. And I started accordingly, and it took nearly 1 hr 15 min to complete. To built and backend application from scratch within 1hr 15 min, I think it's fair and I was expecting I could clear this round. But there was no response from the organisation.
