I applied via Campus Placement and was interviewed in May 2024. There were 2 interview rounds.
Simple queations with some technical questions
Digital signals are discrete and represent information in binary form, while continuous signals are analog and represent information in a continuous manner.
Digital signals have a finite set of possible values (0 or 1), while continuous signals can have an infinite number of values within a range.
Digital signals are more immune to noise and distortion compared to continuous signals.
Examples of digital signals include co...
Various types of antennas are used for different applications, including dipole, Yagi, patch, and parabolic antennas.
Dipole antennas are simple and commonly used for radio and television broadcasting.
Yagi antennas are directional and used for long-distance communication.
Patch antennas are compact and used in wireless communication systems.
Parabolic antennas are used for satellite communication and have high gain.
Easy basics of telecommunication

Qsns related to 4G communication,LAN etc
Sampling theorem states that a continuous signal can be perfectly reconstructed from its samples if the sampling rate is greater than twice the highest frequency component of the signal.
The Nyquist-Shannon sampling theorem states that in order to accurately reconstruct a signal, the sampling rate must be at least twice the highest frequency component of the signal.
If the sampling rate is too low, aliasing can occur, le...

As per JD, i was being offered for a security Intern role and for this job description we have following in aptitude test:
20 questions in Problem Solving assesment and included topics were : Profit and Loss, HCM and LCM, simple interest, compound interest, Number system, Time & Work, Time, speed & distance, Ratio Analysis, Set theory, Profit & Loss, Percentages and Algebra.
30 questions from Technical topics like programming, coding, security and DBMS and oops.
And 10 questions from English Proficiency and communication .
There were 2 questions from security and management and questions were related to brute force, CTF and sort of simple concepts in LINUX.
CIA stands for Confidentiality, Integrity, and Availability in cyber security.
Confidentiality refers to protecting sensitive information from unauthorized access.
Integrity ensures that data remains accurate, complete, and unaltered.
Availability ensures that systems and data are accessible and usable when needed.
These three principles form the foundation of a secure cyber environment.
Example: Encrypting data to maintain...
To determine if a system is compromised or vulnerable, conduct regular vulnerability scans and penetration testing.
Perform regular vulnerability scans using tools like Nessus or OpenVAS
Conduct penetration testing to simulate attacks and identify vulnerabilities
Monitor system logs for suspicious activity
Stay up-to-date with security patches and updates
Use intrusion detection and prevention systems
Perform code reviews an...
Penetration testing is a simulated cyber attack on a computer system to identify vulnerabilities and assess security measures.
It involves attempting to exploit weaknesses in a system's defenses
The goal is to identify potential security risks and provide recommendations for improvement
Penetration testing can be done manually or with automated tools
Examples of penetration testing include network penetration testing, web ...
Standard tools for assessing system security
Vulnerability scanners (e.g. Nessus, OpenVAS)
Penetration testing tools (e.g. Metasploit, Nmap)
Network analyzers (e.g. Wireshark, tcpdump)
Log analysis tools (e.g. Splunk, ELK Stack)
Firewall and intrusion detection systems (e.g. Snort, Suricata)

English communication test
Reasoning in Aptitude
Computer Networks are systems of interconnected computers that communicate with each other to share resources and information.
Computer networks allow for sharing of resources such as files, printers, and internet connections.
They enable communication between devices through protocols like TCP/IP.
Examples include LANs (Local Area Networks), WANs (Wide Area Networks), and the Internet.
VPN stands for Virtual Private Network, it allows users to securely access a private network over a public network.
VPN encrypts data to ensure secure transmission over the internet
It masks the user's IP address to maintain anonymity
VPN creates a secure tunnel between the user's device and the private network
Common uses include remote access to company networks and bypassing geo-restrictions
Examples of VPN services incl...
I applied via Campus Placement and was interviewed in Jul 2022. There were 2 interview rounds.
The 1st round is a written test. The written test consists of some Aptitude questions,technical and 2 coding questions.
A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle.
Applications include function call stack, undo-redo operations, infix to postfix conversion, and backtracking algorithms.
Push and pop operations are used to add and remove elements from the stack, respectively.
Fibonacci series can be implemented using a stack or recursion.
Stacks can be implemented using arrays or linked lists.

Modulation is the process of varying a carrier signal's properties to encode information.
Modulation is used in telecommunications to transmit information over long distances.
There are different types of modulation such as amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM).
In AM, the amplitude of the carrier signal is varied in proportion to the waveform being transmitted.
In FM, the frequenc...
