Frequently Asked Questions in Service-Based Companies


Most multinational companies are service-based. A few service-based company examples are Accenture, Wipro, Infosys, TCS, and Cognizant. These companies provide services to their clients or customers or offer solutions to the problems of bigger companies.

If you are wondering how to switch from Infosys to other product-based companies, then this article is probably not for you. But to those wondering how to get placed in a service-based company then please keep reading.

What are Service-based Companies?

Service-based companies provide a wide range of services like research and development, system integration, outsourcing information systems, and information technology. Clients or customers approach these companies. Employees here create, deploy, maintain or perform all the three functions according to the requirements of the client.

The service-based company may work on products as well but those products belong to other companies or clients. Thus, we must keep this in mind when preparing for any upcoming interviews. Service-based companies heavily focus on IT as a service as well, thus generally requiring applicants to always sit for coding rounds after the initial aptitude test.

Commonly Asked Questions in the Aptitude Section

You need to solve aptitude questions during the written test. We have handpicked a few aptitude questions to look at to have an understanding of what you can encounter during the real test.

Assume that the speed of the river is ‘x’ km/hr.

Speed of the swimmer in still water = 8 km/hr

Speed of the swimmer against the flow of the river = 4 km/hr

Applying the equation:

4 = 8 – x

x = 4 km/hr

Q. Sam’s father is twice as old as his son. If 25 years ago, the age of Sam’s father was 10 times the age of the son, what is the present age of the father?

  1. 53 years old
  2. 54 years old

      (C) 55 years old

      (D) 56 years old

Ans: (D)


Assume Sam’s age to be ‘x’ years

Age of Sam’s father would be = ‘2x’

As per question 25 years ago;

10 (x – 25) = 2x – 25

10x – 250 = 2x – 25

8x = 225

x = 225/8 = 28.125 

Age of Sam’s father = 28.125 * 2 = 56 years (approximately)

Q. An open faucet can fill a reservoir in 4 hours. The drain at the bottom of the reservoir empties it in 8 hours. If both the faucet and the drain are left open, how long will it take to completely fill the reservoir?

  1. 6 hours
  2. 8 hours
  3. 10 hours
  4. 12 hours

Ans : (B)


The open faucet will fill the reservoir in 4 hours.
In one hour the open faucet will fill 1/4th of the reservoir.

The drain at the bottom of the reservoir will empty the reservoir in 8 hours.
In one hour the drain will empty 1/8th of the reservoir.

Therefore in one hour 1/4th – 1/8th =  1/8th of the reservoir will be filled.

Hence, if both the faucet and the drain are left open then it will take 8 hours to completely fill the reservoir.
