Wrost Juspay Interview Experience Oncampus sde backend intern 2025 #juspay #hackathon juspay 📌 Opportunity: On-Campus (Open to All Branches) Position: SDE Intern – Backend College tier-3 Compensation- 27Lpa I cleared 5 rounds and finally reached the last round of the interview. This was supposed to be a system design round. The HR had informed me that the interview would consist of questions from OS, DBMS, Computer Science fundamentals, and OOPs—essentially core subjects. Firstly, the interviewer joined 1.5 hours late. When he finally joined, he said, “Please allow me 2 minutes, I need to use the washroom.” I politely said, “Go ahead, sir.” When he returned, the first thing he asked was, “Do you know how a toilet flush works?” Honestly, I didn’t know the technical workings, but I had seen some Harpic advertisements on TV. So, I tried to answer by saying, “Sir, I think there's some rubber mechanism that holds water, and when we press the flush button, it releases the water.” To that, he bluntly replied, “Nahi aata to chup raho” (If you don’t know, keep your mouth shut). I understand that if I didn’t know the answer, I should have stayed quiet—but I thought giving a logical guess or intuition might show I'm trying. Then he asked me my favorite subject. I replied with a core subject that I enjoy. But he interrupted and said, “Not from your core or engineering subjects.” So I told him, “Sir, space fascinates me.” His counter-question was, “If you're stuck on a planet like Earth, how would you build a spaceship using only Earth’s resources?” I admitted honestly, “Sir, I don’t know, I’m from the CSE branch,” especially since at the beginning of the interview he himself said, “If you don’t know the answer, don’t try to answer.” Next, he shared 8 components. He asked me to build a steam engine using them. Again, I said, “Sorry sir, I don’t know.” He said, “No worries, let’s move to your technical skills.” Then he asked me how a HashMap works in O(1) time complexity. Since I use Java, I explained how HashMaps work both before and after Java 8. After that, he simply said, your interview is over.”
