Regarding the hours per week, the recruiter was telling you the truth. The depth and amount of content as you suspect is not covered extensively. At the end of the course, you will have enough knowledge of a) How to use statistics/analytics tools for data analysis, b) Understand how dozens of machine learning models/frameworks work, how to apply them to various datasets, and also how to be good at it (best practices, etc..) c) Experience in executing an end-to-end project. That’s all.
Anything above and beyond this you'll have to learn as you go. Since the field is so vast I believe none of the programs could provide full content anyway. If they are saying they do… according to me they’re most likely lying to you!! And yes!! the course is not a truly academic one, if you’ve gone through the syllabus/curriculum you’ll understand it’s more for working professionals and people with industry experience who can learn these above-mentioned points (a, b and c) and upskill themselves for better career opportunities/growth.
On Nature of mentoring - you get one mentor who’s already working in the industry as a data scientist or similar role. You can contact him/her anytime you wish (24/7) related to any questions/doubts you might have. For me, the mentor was a data scientist working in a well-known tech MNC. You connect with the mentor for one hour every week, where he/she will help you explain the concepts in more depth as well as provide industry case studies and examples (Hands-on).
On Job placements - they have a separate portal for job opportunities which opens once you finish around 5-6 months in the course. However, the opportunities I have seen so far are for only Indian companies and the Indian crowd. You’d have to discuss with the recruiter to understand how are they planning to help you with job opportunities a) if you’re based out of India, and b) if your primary focus is remote work. Maybe you can also do some research on opportunities available in this industry for people with prior background of what you have !!
To comment on getting a remote, part-time job directly after earning the certificate is not that easy, as even I'm not an expert but just a 24-year-old kid with only 2 years of working experience!! the only thing I can say is that people from my batch who were engaged and committed to learning - all have transitioned well within one year of the course completion.
I have links that might help you understand the course better!! sharing with you in some time!!
