I have 3.3 years of experience as a Java, Spring Boot developer. Currently I want to switch from TCS, but not getting any calls from other

Java is a dying tech its mostly in legacy systems

switch to other its better now Go lang has taken over new microservices way lot better cause it integrates better with cloud tech cause mostly go lang is used to develop those technologies

I think it's because of current scenario in the sector which is going at tough phase.. would suggest to never lose,be patient by trying until you finally land with a good offer...
