Recruiter called. Scheduled 1 round after basic discussion.

Tech Interview 1: DSA based, conducted by a staff engineer. After passing the first round, 2 more rounds were scheduled within the following week.

Tech Interview 2: Focused on HLD and API design skills. Tech Interview 3: Combined technical and behavioral aspects.

The hiring manager round was scheduled after the above two rounds. I haven't heard from the recruiter since then. It has been one month since the last interview (hiring manager). There has been no feedback, no rejection, nothing.

Why rush through interviews when you don't even care about a candidate's time and effort?

Focus on basic Data Structures and Algorithms (DSA).

Prepare for High-Level Design (HLD) questions, including designing specific systems.

All interview rounds will be conducted by Principal and Staff-level engineers, so ensure your answers are technically sound and avoid unsubstantiated claims.
