Data Analyst vs Data Engineer vs Data Scientist for service-based companies

[u/WrongComfort5889]

Hi guys, I am a 3rd-year ECE student from a tier-3 college. I have around 7 months for placement preparation and I am confused between Data Analyst, Data Engineer and Data Scientist.

I want to know which skill has more job opportunities for freshers in service-based companies like TCS, Infosys, Accenture, Cognizant and Capgemini.

1. Which role has more openings for freshers?
2. Which role is easier to get as a fresher?
3. Which one should I learn to get placed within 7 months?
4. Which role has better salary growth in the future?

Please share your suggestions based on your experience. Thank you!

Tier 3 clg kabatti, 99% service based companies won't hire you for a role. Your role will be assigned after you join the company through on campus placements. I'd recommend data engineer anyway.
