Sharing my interview experience with Jio Hostar

Round 1 : LLD Round
Problem statement : Design a service which talks to LLM, something like backend service for ChatGPT chat interface. It should take prompt, talk to LLM and give back the response. Sessions should be managed. Also gives the options to index files.
Expectation was to write pseudo code and answer some high level system design questions as well.

Round 2: HLD Round
Problem Statement : Design feature for showing current viewing numbers on a streaming video. Both writing the data into backend and reading the data from backend was covered.

Round 3: Hiring Manager
Mostly typical questions - Most difficult project. What kind of metrics do you use in your systems, how to handle failure, debugging, oncall process. role in the team. What happens in your 1:1 calls. How does PR reviews etc work?
Design Cart management system, functional and non functional requirements, what all metrics you want to see. Which database.

Overall Verdict: Rejected
Last round didn't go as well, wasn't fully prepared.
