Yes, Industrial training is useful for those who knows why they are doing it. Firstly, it provides exposure to industry resulting into personality improvement n getting a brownie point in ur resume. If ur articleship is not from top 10 u can go for it. Moreover if u can get an Ind Training in a company u intend to work in future, thn theres nothing better than tht.
However if u wish to move into practice, consultancy or buisness etc, thn i wud prefer to say tht u'll waste ur time.
All requirements are posted on ICAI website, get them from there.
Hope it helps u! IF u need to know anything specific thn PM me.
