An anonymous user shared their experience for an SDE role after being contacted by a recruiter on LinkedIn. The interview process involved two technical rounds and one hiring manager round.

Round 1: Technical Round
This round included two coding questions of medium-hard LeetCode level. One question was based on arrays, and the other on linked lists. The candidate successfully solved both problems, and their code passed all provided test cases.

Round 2: Technical Round
This round, held on the same day as Round 1, featured a stack-based coding question. Following this, numerous questions were asked about MySQL, requiring the candidate to write queries for specific problems. OOPs concepts, including the singleton pattern, were also covered. This round was comprehensive, testing a wide range of technical knowledge.

Round 3: Hiring Manager Round
The Vice President initially spoke about the company. Then, a simple array-based question was posed, with an emphasis on providing a highly optimized space-wise solution. The candidate provided the required solution. The round concluded with discussions about the candidate's current project and cultural fitment questions.

Two days later, the candidate received an offer letter for the role.
