IoT Interview Questions, Part Two: Healthcare, Agriculture, Transportation

The Internet of Things (IoT) job market in India in 2023 is expected to experience exponential growth. According to data from a report by DATAQUEST, “The Indian IoT market is expected to grow at a CAGR of 17.1%. It is expected to reach USD 1 Trillion in the next 5–7 years.”

What does this mean for the Indian job market? Here are the top three takeaways:

  • The IoT industry is expected to generate several thousand jobs in India in the near future.
  • The government and private sector will continue to invest in IoT (and other emerging technologies).
  • There will be a strong focus on hiring professionals who can help companies gain a competitive edge in the market.

As a hiring manager, you’ll be tasked with hiring software developers, data scientists, system engineers, security professionals, and many others—all of whom have the skills and experience to both develop and manage IoT-based solutions.

Before we get ahead of ourselves, let’s identify which industries will be most affected by IoT in India. From there, we can determine which interview questions to ask job candidates.

In part two of this series, let’s take a look at three industries: healthcare, agriculture, and transportation.


IoT has tremendously impacted the healthcare industry, from improving patient care to enabling remote monitoring and diagnosis of patients. IoT technology allows healthcare providers to monitor patients’ vital signs—such as blood pressure, heart rate, and oxygen levels—from a remote location. This can enable faster diagnosis of medical conditions and proactive treatment and care.

What You Should Ask

Describe a project in which you have used IoT to improve the healthcare system. What challenges did you encounter, and how did you overcome them?

How They Should Answer

Projects might include:

  1. Remote patient monitoring: Leveraging sensors and connected devices to monitor patient vitals remotely and alert healthcare providers of any changes.
  2. Automated medication delivery: Using IoT to automate the delivery of medication to patients, ensuring that they receive their medications on time and in the proper doses.
  3. Wearable devices: Utilizing wearable devices like smartwatches and fitness trackers to track and monitor patient health data.
  4. Smart hospital rooms: Equipping hospital rooms with connected devices ,like smart beds, to provide real-time feedback on patient conditions.
  5. Mobile health applications: Developing mobile health applications that allow patients to access their health records and communicate with healthcare providers.


IoT technology has the potential to revolutionize the agriculture industry by helping farmers make more informed decisions. IoT sensors can be used to monitor the soil and climate conditions in a field, providing the farmer with real-time data to inform decisions on when to irrigate, fertilize, and harvest crops. IoT-enabled devices can also be used to control irrigation systems and monitor the health of livestock.

What You Should Ask

How do you ensure that the data collected from agricultural IoT devices is accurate and secure?

How They Should Answer

  1. The best way to ensure that data collected from agricultural IoT devices is accurate and secure is to utilize an encrypted secure communication protocol such as TLS or IPsec.
  2. Additionally, it is important to ensure that the IoT devices are regularly updated with the latest security patches and firmware, as well as regularly audited for accuracy.
  3. Utilizing strong authentication and access control methods, such as multi-factor authentication, can also help ensure that the data remains secure and accurate.


IoT has had a huge impact on the transportation industry. IoT technology has enabled transportation companies to increase efficiency and reduce costs. IoT-enabled vehicles can monitor driver behavior, improve safety, and optimize routing and scheduling. IoT also enables real-time tracking of shipments, improved customer service, and automated maintenance and repair.

What You Should Ask

What are some ways you’ve implemented a IoT system to improve safety?

How They Should Answer

  1. An IoT professional could improve safety in the transportation industry by using sensors to monitor and track vehicles.
  2. Sensors could be used to detect problems with the engine, brakes, and tires, as well as monitor air pressure, fuel levels, and other vital metrics.
  3. Connected devices such as dash cams, collision avoidance systems, and GPS tracking could help monitor driver behavior and provide real-time alerts to help prevent accidents.
  4. Data collected from these devices could be used to identify trends and potential risks and develop strategies to mitigate them.
