There are courses from General Assembly and Mages Institute where they will assist you in looking for a job after course completion. I'm looking at Data science/analytics related courses. Any advise?

Go check out Le Wagon! Can't say about their Data Science course but I took their Web Development course and it was amazing. The school will assist you in your job search but there is no guarantee. You will have to work hard - send out resume to tons of companies, attend many interviews, etc. All the best in your tech journey!

I am also interested in General assembly. They seem more reputable but it is very costly. The preview sessions I attended were really good too. Learnt alot during the free previews.

Mages seems to have a poorer reputation and not as widely recognized so I did not really take them into consideration. Many have not heard of it.
