Senior Engineer 1 Interview Questions and Answers

The size of a class with virtual functions is larger than the size of a class without virtual functions due to the additional overhead of virtual function tables.

• Classes with virtual functions have an additional pointer to the virtual function table (vtable) which increases their size.

• The size of a class without virtual functions is determined by the size of its data members and any padding added for alignment.

• For example, a class with virtual functions may be 8 bytes larger ...read more

8D is a problem-solving methodology used to identify, correct, and prevent recurring problems.

• 8D stands for 8 Disciplines

• It involves identifying the problem, containing it, identifying the root cause, and implementing corrective actions

• It also involves implementing preventive measures to avoid recurrence of the problem

• The 8D process includes steps such as creating a team, defining the problem, implementing containment actions, identifying root cause, implementing corrective a...read more

Reversing a linked list involves changing the direction of pointers, while reversing a doubly linked list allows for traversal in both directions.

• To reverse a linked list, iterate through the list and change the direction of pointers to point to the previous node instead of the next node.

• In a doubly linked list, reversing allows for traversal in both directions, making operations like deletion and insertion more efficient.

• Example: Reversing a linked list: 1 -> 2 -> 3 -> 4 -> ...read more

Modal analysis is a technique used to study the dynamic behavior of structures under different loads.

• Modal analysis helps in identifying the natural frequencies and mode shapes of a structure.

• It is used to determine the response of a structure to different types of loads such as vibrations, earthquakes, and wind loads.

• Modal analysis is commonly used in the aerospace, automotive, and civil engineering industries.

• It can be performed using experimental methods such as impact tes...read more
