Summary
I recently interviewed with JioHotstar for a Backend Engineer role. The process involved multiple rounds covering DSA, LLD, HM, and a bar raiser system design, but I did not receive an offer.
Full Experience
I recently interviewed with JioHotstar for a Backend Engineer role with ~1.8 years of experience. The process started after a call from the hiring manager, followed by an HR screening.
-
The first round focused on a tough DSA problem: Max sum of two non-overlapping subarrays using prefix sum + sliding window. The second round included a valid parentheses question and a custom XML-like parser more about clean code and implementation.
-
The LLD round was on designing a stock exchange order matcher, where I used priority queues and explained scalability. The HM round mixed behavioral and technical questions around past projects, decision-making, and impact metrics.
-
Finally, the bar raiser was a high-level system design — I built a Swiggy-like system, discussed microservices, queues, and real-time challenges.
Although I didn’t get the offer, the process was fast and insightful. Great learning in terms of depth, articulation, and real-world design prep!
