I am a bachelors in computer engineering and want to start data science career. Is it must to do MS in data science or courses are enough for a job in this field?
Sometimes doing MS in Data Science cannot guarantee you a job, and sometimes courses can earn you a job or vice versa.
Frankly, getting a job depends on your knowledge, skillset and communication skills.
Transition into Data Science field might be easy as you already know coding being a computer science student.
I would suggest that you go through a few courses and if you find this field interesting, then go for a solidified knowledge in this domain.
