I'm an experienced programmer. Now I'm venturing into Big Data domain where my knowledge is extremely limited.
I would like to take a course on a particular subject in this area. I have already found one and it seems OK to me, though there are others of course.
Would it be appropriate to ask the following questions on this site:
Has someone taken XYZ course from ABC company? If so, could you please share your experience?
What other classes that your personally took would you recommend to others and why?
I understand that at least some of the answers will be extremely subjective ("Like - Don't like" perspective). Is it a big NO here or can it be tolerated as long as I'm not asking general questions about the best training ever but keep it focused on much narrower topic?
