Inquiry about CS Training

 I talked with few PCS where one firm is engage in Insolvency related assignments & their Co- firm is engaged in secretarial compliances but not LODR.

Another firm which is engaged in core secretarial compliances unlisted & Private companies. FEMA.

Third one is engaged in Secretarial Audit, FEMA, And few aspects of LODR.

Which firm should i select ?

As i understood in one firm all things i will not get such as M & A's , LORD, FEMA, & Core secretarial .

I am confused what to do , as it is there in my mind that if anything i will not do in training so how will i do it in future if such assignment comes to me is it so?

Or such skills can be acquired such as LODR Compliances

. Kindly guide me.

Thanks in Advance
