ALTEN Interview Questions and Answers

Q1. What is MHR & Cycle Time
Ans. 
MHR stands for Maximum Heart Rate, the highest heart rate a person can achieve during exercise. Cycle Time is the time taken to complete one cycle of a process.
• MHR is often used to determine target heart rate zones for exercise.

• Cycle Time is important in manufacturing processes to optimize efficiency.

• For example, if someone's MHR is 180 bpm, they may aim to exercise at 70-85% of that rate.

• In a manufacturing setting, re...read more

Q2. What is differance between VMC, HMC
Ans. 
VMC stands for Vertical Machining Center and HMC stands for Horizontal Machining Center. The main difference lies in the orientation of the spindle.
• VMC has a vertical spindle orientation, while HMC has a horizontal spindle orientation.

• VMC is ideal for producing parts with complex geometries that require a lot of tool changes, while HMC is better suited for parts that can be machined in a single setup.

• HMC typically has ...read more

Q2. Difference between structures and union
Ans. 
Structures are used to store different data types under a single name, while unions allow storing only one value at a time.
• Structures can store multiple values of different data types under a single name, while unions can store only one value at a time.

• In structures, each member has its own memory location, while in unions, all members share the same memory location.

• Structures are used when different types of data need...read more

Q2. Newtons three equations
Ans. 
Newton's three equations describe the relationship between forces and motion.
• First law: An object at rest stays at rest, an object in motion stays in motion unless acted upon by an external force.

• Second law: F = ma, where force is equal to mass times acceleration.

• Third law: For every action, there is an equal and opposite reaction.
