Vem Technologies Interview Questions and Answers
21 Interview questions
Storage classes in C define the scope, lifetime, and visibility of variables, influencing memory management and access.
auto: Default storage class for local variables, with automatic duration. Example: 'int x;' inside a function.
register: Suggests storing the variable in CPU registers for faster access. Example: 'register int count;'
static: Preserves variable value between function calls and limits visibility to t...
SPI, I2C, and UART are communication protocols used for data exchange between devices, each with unique characteristics.
SPI (Serial Peripheral Interface): A synchronous protocol that uses multiple lines for communication, allowing for high-speed data transfer. Example: Connecting a microcontroller to an SD card.
I2C (Inter-Integrated Circuit): A synchronous, multi-master, multi-slave protocol that uses only two wir...
Volatile and constant keywords control variable behavior in programming, ensuring proper memory access and immutability.
The 'volatile' keyword indicates that a variable's value may change unexpectedly, preventing compiler optimizations.
Example: 'volatile int flag;' ensures the flag is always read from memory, not cached.
The 'const' keyword defines a variable whose value cannot be changed after initialization.
Examp...

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).
Converts AC to DC by allowing current to flow in one direction only
Commonly used in power supplies and electronic devices
Types include half-wave, full-wave, and bridge rectifiers
Diodes are often used in rectifier circuits
My favorite language is Python because of its simplicity, readability, and versatility.
Python is known for its clean and readable syntax, making it easy to learn and use.
Python has a wide range of applications, from web development to data analysis and machine learning.
Python has a large and active community, providing support and resources for developers.
Examples: Django for web development, pandas for data analy...
A boost converter is a type of DC-DC converter that steps up the input voltage to a higher output voltage.
Use a switch (usually a MOSFET) to control the energy flow from input to output
Include an inductor to store and release energy
Add a diode to allow current flow in one direction
Use a capacitor to smooth out the output voltage
Implement a control circuit to regulate the output voltage
Armature voltage control involves changing the voltage applied to the armature of a DC motor to control its speed, while field control involves changing the field current to control the motor's speed.
Armature voltage control adjusts the voltage applied to the armature winding of a DC motor to control its speed
Field control adjusts the field current in the motor to control its speed
Armature voltage control is more ...
Choose a MOSFET based on voltage, current, power dissipation, switching speed, and package type.
Consider voltage and current requirements
Look at power dissipation and thermal considerations
Evaluate switching speed needed for the application
Choose the appropriate package type for mounting and heat dissipation
Check for additional features like built-in protection circuits
Example: For high power applications, choose ...
A Zenor diode is a type of diode that is designed to operate in the reverse breakdown region.
It is also known as a voltage reference or voltage regulator diode.
It is used to regulate voltage in electronic circuits.
It allows current to flow in the reverse direction when the voltage exceeds a certain threshold.
It maintains a constant voltage across its terminals.
It is commonly used in voltage clamping applications a...

Interview Preparation Tips
I appeared for an interview in Oct 2023.
(5 Questions)
- Q1. Moderate and Basic of electronic domain questions. Interview might take 30-40 mins.
- Q2. Construction of types of transistor
- Ans.
Transistors are electronic devices made of semiconductor material that can amplify or switch electronic signals.
Transistors are typically constructed using materials like silicon or germanium.
There are three main types of transistors: bipolar junction transistors (BJTs), field-effect transistors (FETs), and insulated-gate bipolar transistors (IGBTs).
Transistors consist of three layers: the emitter, base, and collector ...
- Q3. About microcontroller and microprocessor
- Q4. Types of memories
- Ans.
Types of memories include sensory memory, short-term memory, and long-term memory.
Sensory memory holds information from the senses for a very short duration.
Short-term memory stores information temporarily for immediate use.
Long-term memory is for storing information for a longer period of time.
Examples: Seeing a flash of light (sensory memory), remembering a phone number temporarily (short-term memory), recalling chil...

- Q2. Units of op amp CMRR
- Ans.
CMRR is measured in decibels (dB).
CMRR stands for Common Mode Rejection Ratio.
It is a measure of an op amp's ability to reject common mode signals.
CMRR is expressed in decibels (dB).
A higher CMRR value indicates better rejection of common mode signals.
For example, an op amp with a CMRR of 80 dB can reject common mode signals 100 times better than an op amp with a CMRR of 60 dB.
