Ques:- Your company installed an ERP system 3 years ago, spending a cumulative $100M to do so. The CEO asks you, was this a financially sound investment?
Right Answer:
To determine if the ERP system was a financially sound investment, we need to analyze the return on investment (ROI). We should compare the cumulative benefits gained from the ERP system over the past 3 years against the $100M spent. If the benefits exceed $100M, it was a sound investment; if not, it was not financially sound.
Ques:- An elevator company wants to know why their sales have fallen and with it their profits. Quantify the loss they have made. Tell me how we need to get around it.
Right Answer:
To quantify the loss, analyze sales data over the past year, comparing it to previous years to identify the percentage decrease in sales and profits. For example, if sales dropped from $1 million to $700,000, that’s a 30% decrease, leading to a proportional profit loss.

To address the issue, conduct market research to understand customer needs, improve product features, enhance marketing strategies, and explore new markets or partnerships. Additionally, gather feedback from customers and sales teams to identify specific pain points and adjust offerings accordingly.
Ques:- If I gave you a billion dollars, what would you do with it?
Right Answer:
I would invest a significant portion in diverse assets for long-term growth, allocate funds for philanthropic initiatives to address social issues, and set aside some for personal and family needs.
Ques:- How do you approach adapting to new company cultures or working with diverse teams
Right Answer:
I approach adapting to new company cultures by observing and understanding the values and norms of the organization. I actively listen to my colleagues, ask questions, and seek feedback to align my work style with the team. When working with diverse teams, I embrace different perspectives, promote open communication, and foster an inclusive environment to ensure everyone feels valued and heard.
Ques:- Can you describe a time when you had to adjust your communication style to work effectively with a colleague or client
Right Answer:
In my previous job, I worked with a colleague who preferred detailed written communication over verbal discussions. To adapt, I started sending more comprehensive emails and reports, ensuring I included all necessary information. This change helped us collaborate more effectively and improved our project outcomes.
Ques:- Can you describe a time when you had to quickly adapt to a significant change at work
Right Answer:
In my previous job, our team had to switch to a new project management tool with little notice. I quickly learned the new software by attending training sessions and exploring its features. I also helped my teammates by sharing tips and creating a guide, which helped us transition smoothly and maintain our productivity.
Ques:- How do you maintain productivity when faced with new or unfamiliar tasks
Right Answer:
I maintain productivity with new or unfamiliar tasks by breaking them down into smaller steps, prioritizing tasks, seeking clarification when needed, using available resources, and staying organized. I also set specific goals and deadlines to keep myself focused and motivated.
Ques:- Tell us about a situation where you had to learn a new skill or technology quickly to succeed in your role
Right Answer:
In my previous job, I was assigned to a project that required knowledge of a new programming language, Python. I had only a basic understanding of it, so I dedicated a week to online courses and tutorials. I practiced by building small projects and sought help from colleagues who were experienced in Python. By the end of the week, I was able to contribute effectively to the project, and we successfully met our deadlines.
Ques:- In 50 mw generator if field is open in full load running condition what happen and for protection which relay used?
Right Answer:
If the field is open in a 50 MW generator while running at full load, the generator will lose its excitation, leading to a rapid drop in voltage and potentially causing the generator to become unstable or trip. For protection, an Under-Voltage Relay (UVR) is typically used.
Ques:- Generally transmitter power supply having some range(12v to 35v) but the out put(4-20 mA) must same for given input.If we vary the power supply voltage then output mA also to be change according to V=IR. Is there any voltage regulator in the transmitter ?
Ques:- A 6-pole, 50 Hz, 3-phase synchronous motor and on 8-pole, 50 Hz, 3-phase slip-ring induction motor are mechanically coupled and operate on the same 3-phase, 50 Hz supply. If they are left open-circuited, then the frequency of the voltage produced across any two slip rings would be
Right Answer:
The frequency of the voltage produced across any two slip rings would be 50 Hz.
Ques:- What is the differance of acb and mcb and mccb
Right Answer:
ACB (Air Circuit Breaker), MCB (Miniature Circuit Breaker), and MCCB (Molded Case Circuit Breaker) are all types of circuit breakers used for protection in electrical systems.

- **ACB**: Used for high voltage applications, can handle large currents, and is typically used in industrial settings.
- **MCB**: Protects against overload and short circuits for low voltage applications, automatically switches off when current exceeds a set limit.
- **MCCB**: Similar to MCB but can handle higher currents and provides adjustable settings for overload protection, suitable for medium voltage applications.
Ques:- Which is the best, A/C DRIVES or D/C DRIVES for cranes,………and why……?
Right Answer:
A/C drives are generally considered better for cranes because they offer higher efficiency, better control over speed and torque, reduced maintenance, and the ability to handle varying loads more effectively compared to D/C drives.

Prioritizing tasks, staying organized, and remaining calm are crucial. Finally, I would implement the chosen solution, monitor progress, and adjust as needed while keeping stakeholders informed.
Ques:- WHAT IS MEANT BY 'ZERO VALUE'IN QUANTITY SURVEYING.
Right Answer:
In quantity surveying, 'zero value' refers to items or work that are included in a project but do not have a cost associated with them, often because they are not expected to incur any expenses or are accounted for in other ways.
