Hi Prerna. Congratulations on a new job and such a good hike in your salary. Can you share with us your past experience with Tech Mahindra?

“Thank you. Yes of course. I completed my 3 years of working in a Technical Support Role and later I realized that my learning has become zero. I am a person who cannot sit idle and desire to learn more and more. This thought in my mind made me change my way as I could not get much exposure from this job. So I decided to learn a new technology that can enhance my knowledge and can earn me a better job profile.”

Q. What was your next step when you quit your job?

“After working on PLSQL and Unix, I thought of changing my career path and learn something which is the need of the day. I searched for many technologies and finally made a mind to learn big data as it is the most demanding technology now. It is one such technology that may create wonders if properly put into action.”

New technology is not good or evil in or of itself. It is all about how people choose to use it.
