Java Interview Discussion for Juniors | Spring Boot, Core Java, Microservices, Threads, Redis

Many junior developers grasp Spring Boot but often struggle with fundamental Java concepts during interviews and projects. This video discusses common issues arising from a limited understanding of internal workings, especially concerning "java hashmap" and "threading." We explore how a deeper knowledge of "hashmap internal working" and the "java collections framework" can prevent common software development problems.
