what is your exact experience. For 1.8 years, you should have good grip of any one module atleast like finance TL.

Even if you clear interview, do you think you will survive… as their will be expectation from you and hand-on on ax should be good.

total 1.8 in axapta technical…

what are the concepts i need to know in functional,t&l,administratn

It depends what you want to specialise in and where your background experience is - it is not usual to learn it all in AX.
