Computers & IT (Non-Engg)

Hello Ketan,
You should not get too fascinated with ethical hacker as they show in movies. Most of the institutes provide just a basic fancy course under the name of ethical hacking, just to attract students and earn more.
I would rather recommend you to go for security specialist professionals. These jobs are highly payable and in high demand as most companies need them to protect their own data. These jobs work on the same logic that the best thief can protect the data in the best way.
For the same, you can go to some reputed computer training institutes like NIIT, etc. You can go for Java courses followed by networking courses and CCNA/CCNB (CISCO) courses. After this, you can also opt for CEH (Certified Ethical Hacker) certification courses, if you wish to.
Ensure you do these courses alongside a degree course (BCA, B.Tech, B.Sc, etc.) for better outcome.
I hope I have been able to answer your queries to your satisfaction. If so, kindly upvote this answer.

MCA post graduates are hired both by government agencies NTPC, GAIL, BHEL, etc. and private IT companies like Accenture, Infosys, Wipro, TCS, Cognizant, IBM, American Express, HCL, HP and so on. As a fresher, an MCA professional can expect anything around 2.4 to 3.4 lakhs, and with experience, sky is the limit. With some years of experience, a software engineer can become a lead, an analyst, a project manager, a general manager and so on. Initially MCA students are given a few weeks of training on the job, before they get started on live projects. They need to work in different roles and areas in the beginning and then gradually specialize in a specific field.
