Every now and then, I keep seeing a new company coming up with Hadoop classes/courses. Also, my friends keep asking me which of these courses is good to take. I gave them a few tips to choose the best course suitable for them. Here are the few tips to decide which course you should attend to:
1. Does the instructor have domain expertise?
Know your instructor. You must know about the instructor’s background. Has (s)he done any big data related work? I have seen a lot of instructors who just attend a course somewhere and become instructors.
If the instructor never worked in the domain, do not take such classes. Also, avoid training institutes that do not tell you details about the instructor.
2. Is the instructor hands on? When did she/he code last time?
In the domain of technology, there is a humongous difference between one instructor who is hands-on in coding and another who is delivering based on theoretical knowledge. Also, know when the instructor worked on codes the last time. If instructor never coded, do not attend the class.
3. Does the instructor encourage & answer your questions?
There are many recorded free videos available across the internet. The only reason you would go for live classes would be to get your questions answered and doubts cleared immediately.
If the instructor does not encourage questions and answers, such classes are fairly useless.
