I applied via Naukri.com and was interviewed in Sep 2023. There were 3 interview rounds.
(3 Questions)
- Q1. About my previous projects. How it is designed, developed, Moto of the project. And entire project life cycle.
- Q2. What are types of voltage regulators. Explain them.
- Ans.
Types of voltage regulators include linear regulators, switching regulators, and shunt regulators.
Linear regulators: provide a stable output voltage by dissipating excess power as heat (e.g. LM317)
Switching regulators: more efficient than linear regulators by switching the input voltage on and off (e.g. LM2596)
Shunt regulators: regulate voltage by shunting excess current to ground (e.g. TL431)
- Q3. Working principle of Project that is developed earlier.
- Ans.
The working principle of the project developed earlier involved utilizing machine learning algorithms to analyze data and make predictions.
Used supervised learning techniques to train the model
Implemented feature engineering to improve model performance
Utilized cross-validation to assess model accuracy
Applied the trained model to new data for prediction

- Q1. Introduce yourself
- Q2. Tell us about your project briefly
- Q3. I am from ECE and my project is based on embedded systems. so they started asking about ARDUINO and relay module I have used like output current from Arduino, supply used, about relay and optocouplers
- Q4. Draw a rough circuit diagram of your project and explain briefly about the programming done to it
- Q5. Draw and explain a full wave bridge rectifier. explain the losses in transformer and working principle of it. why the filters are used etc. and about Zener diode characteristics and its usage as regulator
- Ans.
Explanation of full wave bridge rectifier, transformer losses, filter usage, and Zener diode as regulator.
Full wave bridge rectifier converts AC to DC using four diodes arranged in a bridge configuration
Transformer losses occur due to core saturation and resistance in the windings
Filters are used to smooth out the DC output and reduce ripple
Zener diode operates in reverse breakdown region and maintains a constant volta...

- Ans.
Comparison of 8086 with present processors and why PC processors can't be used in mobiles
8086 had a 16-bit data bus and 20-bit address bus, while modern processors have 64-bit data bus and 48-bit address bus
8086 had a clock speed of 5-10 MHz, while modern processors have clock speeds in GHz
Mobile processors are designed to be power-efficient and have lower clock speeds compared to PC processors
Mobile devices use differ...
