Its a trap. they charge less money from student for courses because their trainers are among their recently trained students.
I am surprised, how those people DARE to become a trainer. I enrolled for online Linux and Aws. believe me, they aligned a trainer to me who have total 2 yr of industry experience, he was 2017 college pass-out.
Later they changed to an another Chennai lady, and she just knows aws what "Cloud Guru" tutorial says in Udemy. She will run Cloud Guru video on her laptop and will keep reading the content(Even Labs are line to line same as "Cloud Guru"). She has no knowledge on AWS other than that. If you ask anything which is out of the track they won’t be able to answer and you will easily got to know that they are just freshers like other. They are just taught well how to drive the online course following the built in content and videos, Specially beware of Mr. Udaya. He will speak lots of good words and get you enrolled and will never pick your call afterwards.
