The manager have psychological disorders. Definitely needs to visit psychiatric.
He does not understand your logic and does not want to understand/listen you that it takes time to prepare a candidate equal to candidate with 4-5 years of experience. They will hire you as a solver of technical interviews and if you can not make their candidates clear interviews will fire you.
They are providing fake candidates from java, android, .net, iOS etc technologies. Be respectful while talking to females at-least. I wonder how he will be dealing with guys out there.
!!!do not join them at all!!!
Still want to join? ok join part time and see and then decide to join full time, you will never join them.
Only recruitment/staffing is a good place where they have not fired people, may be human managers working in those teams.
