Toshniwal Instruments interview questions

First it was a basic 20 MCQ and fill the blanks, After that there was interview based on these questions and my resume. Finally Hr discussed salary and duties. They proposed 2 yrs of contract, that i cannot break i have to pay 3 months of salary in advance. They were not clear with the role they are providing, they said you’ll do little bit of everything. I asked them give me a written set of scope for me, they failed to give me that.
