I applied through LinkedIn, and then a TCS HR representative called me, took some basic details, and scheduled my interview.
Preparation
Duration: 1 month
Topics: Java Theory, Design Patterns, Microservice Patterns
Tip 1: For service-based companies, you should focus on the theoretical aspects rather than DSA.
Tip 2: Prepare well with the Stream API, and it's beneficial to have knowledge of Microservices.
