I applied via Superset and was interviewed in Apr 2022. There were 3 interview rounds.
A network is a group of interconnected devices that communicate with each other. OSI layers are a model for understanding network communication.
OSI layers are a conceptual model for understanding how data is transmitted over a network.
There are seven layers in the OSI model, each with a specific function.
The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer communica...
TCP is a protocol used for reliable transmission of data over networks.
TCP stands for Transmission Control Protocol.
It is a connection-oriented protocol that ensures reliable delivery of data packets.
TCP uses a three-way handshake to establish a connection between two devices.
It provides flow control, congestion control, and error detection and correction mechanisms.
TCP is used for applications that require reliable da...
IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses.
IPv4 allows for approximately 4.3 billion unique addresses while IPv6 allows for approximately 340 undecillion unique addresses.
IPv6 includes built-in security features such as IPsec while IPv4 requires additional security protocols.
IPv6 also includes features such as stateless address autoconfiguration and multicast addressing.
IPv4 headers are 20 bytes long ...
There are several types of networks, including LAN, WAN, MAN, WLAN, and VPN.
LAN (Local Area Network) - a network that connects devices within a small area, such as a home or office.
WAN (Wide Area Network) - a network that connects devices across a large geographical area, such as the internet.
MAN (Metropolitan Area Network) - a network that connects devices within a city or metropolitan area.
WLAN (Wireless Local Area N...

I applied via Walk-in and was interviewed before May 2022. There were 3 interview rounds.
OSI (Open Systems Interconnection) layer is a conceptual model that describes the communication functions of a telecommunication or computing system.
OSI model has 7 layers, each with a specific function
Each layer communicates with the layer above and below it
Layers are numbered from 1 to 7, with 1 being the physical layer and 7 being the application layer
Examples of layers include physical layer, data link layer, netwo...

I applied via Job Portal and was interviewed in Dec 2024. There was 1 interview round.
Normal communication check
A loop is a sequence of instructions that is continually repeated until a certain condition is met. An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network.
A loop is used in programming to execute a block of code repeatedly until a specific condition is met.
There are different types of loops such as for loop, while loop, and do-while loop.
An IP address is us...
BGP, OSPF, and VPN are all protocols used in networking to facilitate communication and secure data transmission.
BGP (Border Gateway Protocol) is used to exchange routing information between different autonomous systems on the internet.
OSPF (Open Shortest Path First) is an interior gateway protocol used to find the best path for routing within a single autonomous system.
VPN (Virtual Private Network) is a technology tha...
I interned at a telecommunications company where I gained hands-on experience in configuring network devices and troubleshooting network issues.
Configured routers and switches to optimize network performance
Assisted in setting up VLANs and implementing security protocols
Troubleshooted network connectivity issues for end users
Participated in network infrastructure upgrades and maintenance
I applied via Referral and was interviewed in Jun 2024. There was 1 interview round.
Routing is the process of selecting the best path for network traffic to reach its destination.
Routing involves determining the optimal path for data packets to travel from the source to the destination.
Routers use routing tables to make decisions on how to forward packets based on destination IP addresses.
There are different types of routing protocols such as RIP, OSPF, EIGRP, and BGP.
Static routing involves manually ...
Switching is a networking technique used to forward data packets between devices on a computer network.
Switching involves the process of receiving, analyzing, and forwarding data packets within a network.
Switches operate at Layer 2 (Data Link Layer) of the OSI model.
Switches use MAC addresses to determine the destination of data packets.
Switches create separate collision domains and broadcast domains, improving network...
