GE Interview Questions and Answers for Freshers

Maximize sum by selecting elements from array and removing adjacent elements.

• Select element 'i' and remove 'i-1' and 'i+1' from array during each operation.

• Continue until array is empty to maximize sum of selected elements.

• Focus on maximizing sum rather than printing results.

Implement a queue using only stack data structure with predefined functions for FIFO operations.

• Use two stacks to simulate a queue - one for enqueue and one for dequeue operations.

• For enQueue operation, push elements onto the enqueue stack.

• For deQueue operation, if the dequeue stack is empty, transfer elements from enqueue stack to dequeue stack.

• For peek operation, return the top element of the dequeue stack.

• For isEmpty operation, check if both stacks are empty.

• Example: enQue...read more

The T code for Vendor Invoice processing is FB60 in SAP.

• T code FB60 is used in SAP for Vendor Invoice processing.

• FB60 allows users to create, change, display, and post vendor invoices.

• Users can also perform other functions related to vendor invoices using T code FB60.

• Example: To process a vendor invoice, enter T code FB60 in the SAP command field.

Aerodynamics is the study of how air flows around objects. Airplanes use jet engines, propeller engines, and military fighter jets use afterburning turbofan engines.

• Aerodynamics is the study of the motion of air and the interaction between air and solid bodies moving through it.

• Airplanes typically use jet engines, which are powered by the combustion of fuel and air to produce thrust.

• Propeller engines are also used in some airplanes, where the propeller is turned by a piston o...read more

The aviation industry is moving towards increased sustainability, technological advancements, and digitalization.

• Increased focus on sustainability with the development of electric and hybrid aircraft

• Advancements in technology leading to more efficient and autonomous flights

• Digitalization of processes such as ticketing, check-in, and in-flight services

Over-expanded and under-expanded nozzle flows have applications in aerospace propulsion, industrial processes, and research.

• Over-expanded nozzles are used in rocket engines to maximize thrust by allowing the exhaust gases to expand further than ambient pressure.

• Under-expanded nozzles are used in industrial processes such as gas turbines and steam turbines to increase efficiency by accelerating the flow of gases or steam.

• Both types of nozzle flows are studied in research to un...read more

The engine works on two main types of cycles - Otto cycle and Diesel cycle.

• Otto cycle: used in gasoline engines, consists of four processes - isentropic compression, constant volume heat addition, isentropic expansion, and constant volume heat rejection.

• Diesel cycle: used in diesel engines, consists of four processes - isentropic compression, constant pressure heat addition, isentropic expansion, and constant volume heat rejection.

Shock diamonds are a pattern of stationary and moving shock waves in the exhaust plume of an aerospace propulsion system.

• Shock diamonds are also known as Mach disks or Mach rings.

• They are formed due to the interaction of supersonic exhaust flow with the surrounding air.

• The number of shock diamonds can vary depending on the engine design and operating conditions.

• Shock diamonds are often seen in the exhaust plumes of rocket engines, jet engines, and afterburners.
