Mechanical Engineering Interview Questions and Answers Analysis

This document provides detailed answers to a series of common interview questions, likely aimed at mechanical engineering positions. The responses cover a wide range of topics, including core management principles (planning, organizing, directing, and controlling), employee motivation and team building, and technical aspects such as Programmable Logic Controllers (PLC) and reverse engineering methodologies. The answers also address risk management strategies, the importance of mathematical accuracy in product quality, and the distinctions between latching and holding currents in SCRs. Furthermore, the document touches on the use of AutoCAD for simulation, the role of control systems, and the importance of electrical codes like NEC and NFPA standards. It also includes insights on Total Quality Management (TQM), product design considerations, and the role of innovation in enhancing customer satisfaction. The provided answers demonstrate a comprehensive understanding of mechanical engineering principles and practical applications.

Interview question

1
Key points of management are Planning, organizing, directing and controlling. Three of
them are :
 Planning: This is concern with defining goals for a company's future and also determine
mission and resources in order to attain these defined targets.
 Organizing: It means to organize a team and select resources that will assist to met the
define plan. Thus, under this element, assigning work and granting authority are consider
two element of organizing.
 Directing: It refers to the manage the concern and provide direction to the staff members
of a company so that they will assist to meet the define aim.
2.
To keep motivate employees and by effective team building skills lead a team towards
right direction so that they meet the define aim. Also, I make sure that I involve all the team
members while making decision so that it will assist to determine their views and they also feel
they are important part of a team.
3
PLC is Programmable Logic Controller which is an electronic device that execute logic
programmed in memory and also generate the outputs. I do manage this because I have good
experience with regards to PLC and also understand the language of PLC
4
For searching, I choose specific key terms that help to determine the words and then for
documenting information, I always prefer PIE method which means problem, intervention and
evaluation for documenting information.
5
The best approach to solve any engineering problem is reverse engineering in which an
engineer again start rethinking with scratch in order to determine the problem and then find a
solution and then putting back together again.
6
To tackle risk, I use mitigate the risk as an approach of risk that assist me to determine
the strategy that will help to minimize the chance of risk. Risk taking means accepting the risk

which is also a positive approach because it will deal with the situation easily as compared to
others.
7
Yes, mathematical accuracy is related to quality of product because it will help to
determine how much quantity is used to make the product worth for the customers by a
company.
8
Latching current is the forward biased SCR that passes minimum current which anode
current in order to remain forward conduction mode. While holding current has a minimum
value of anode current and it must fall to stop conducting in forward direction. Also, holding
current is less than latching current, while latching current is more than that of a holding current.
9
Yes, I am familiar with Simulation of electronics products with AutoCAD.
10
control system manages, commands, directs, or regulates the behavior of other devices or
systems using control loops. Taking feedback in control system help the organization in
improving the level of control in the organization.
11
NEC is National Electrical Code which is actually made for the practical safeguarding of
persona and property from the hazard which are arise due to use of electricity. SO, NEC is
generally consider as as electrical installation document that protect employee under normal
circumstances.
12
NFPA 70 B is the preventive maintenance of different electrical, electronic and
communication system and equipment of the organization. This are used to prevent equipment
failure. At the same time NFPA 70 C is classified as a Hazardous location classification, which
look at providing safety against hazardous location.
13
TQM help the company in reducing the amount of the error in different sort of
manufacturing activity of an organization. This generally used to help the company in improving
the level of quality of the product. As product of company is having less error.

14
The main key to design product for the organization is to understand the end consumer
for which the product will be targeted by the company. Also need to understand the need and
preference of end customer.
15
Innovation helps the company in improving the product line of the company, this
eventually help the company in improving the customer satisfaction in the organization.
Customer satisfaction is positively linked with the success of the business in long run.
