Seeking advice on current job
Current Job Situation:
I’ve been working at TCS for over 2.5 years, with a total experience of 4.5 years. My salary is 9.6 LPA, and I work with technologies like Casper framework, HTML, CSS, JavaScript, JSP, Java, PL/SQL, and JBoss. While I have good job security and flexibility, I feel like I’m working with outdated technologies and have a lot of leisure time, which is affecting my motivation.
Concerns:
1. Outdated Tech: I’m worried that working with older tech will limit future opportunities. Should I stay or move to a role with newer technologies?
2. Salary: Is my current package competitive for my experience? What salary should I aim for if I switch?
Seeking Advice:
What modern technologies should I learn to stay relevant?
