Ventajas
You can easily get job even if you have active back logs or year back in your engineering. No requirement of communication skills. TA/DA comes at daily basis. Very easy interview.
Desventajas
Firstly you have to deposit 25k as a bond which you are hardly going to complete😓. Actually you'll work as a rigger almost like labour. Forget word "engineer". You have to climb towers, carry antena on your shoulders, pull ropes etc. For 1st month salary is 0😆 then 5k for next 3 and then 8-12k Salary never comes on time. They deduct salary even for minute reasons. Sometimes you even won't know the reason. So hardly you get complete salary at least I had not seen any of my colleagues getting it. No holiday even you have to work on Sundays and remember if you take it your salary is deducted and if you take more than approved leave then per day deduction is equal to your 2 days salary.
