Yes, a BE degree obtained after 3 years of study under the new education policy  should be sufficient for applying to government jobs that list graduation as the minimum qualification.

• The new policy awards a Bachelor of Engineering (BE) degree after successful completion of a three-year program.
  
  
  

• Government jobs typically specify a graduation degree as the minimum qualification, and this refers to a bachelor's degree from a recognized university.

Therefore, the BE degree obtained under the new policy should fulfill the eligibility criteria for government jobs seeking graduates.

I hope it helps!
