Full Experience
Got a HR call directly for the Phone screening round after updating my LinkedIn profile to be open for work. The first round was an OA with one medium DP question and one hard question on HackerRank, with a 90-minute time limit and camera/mic enabled. The second round was a phone screening where the interviewer gave a stack problem. The problem involved merging K cars together and repeating the merge process, returning the final arrangement. For example, given a list of cars, with K=2, the output was a specific arrangement. The interviewer then mentioned that I cleared the phone screening and was selected for the complete interview schedule.
The first DSA round had a question involving some minor math and a line sweep algorithm, but I wasn't able to solve it even after multiple hints, leading to a 'No Hire' decision. The LLD round required designing a voter management system with states, constituencies, districts, and EVMs, expecting working code for at least one feature. I struggled to code properly and was not hired. The HLD round involved designing a feed notification service similar to Instagram, which I handled well and was considered a 'Strong Hire'. The managerial round focused on behavioral questions about my projects and team. Despite the strong hire in the HLD round, the overall outcome was a rejection.
