I applied via Campus Placement and was interviewed in Sep 2020. There were 3 interview rounds.

Interview Questionnaire 

7 Questions

  • Q1. Types of pump, compressors?
  • Ans. 

    Pumps: centrifugal, positive displacement, axial flow. Compressors: reciprocating, rotary, centrifugal.

    • Centrifugal pumps use a rotating impeller to move fluid.

    • Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge.

    • Axial flow pumps use propellers to move fluid.

    • Reciprocating compressors use pistons to compress gas.

    • Rotary compressors use rotating screws or vanes to compress ...
