Ideally nothing. There is one project which is built and only needs implementation engineer to go and deploy in university and demo. You need to have only .net knowledge.
Cons
Worst place for even a fresher as well as experienced.
It's located in a house kind somewhere in a non company area.
No food
No cab
No facilities like WiFi
No EPF
Salary is like low low low level 5k -7k that also not paid in full amount in cash.
Only one project
Worst people first all of that.
