Software Engineer Interview
I applied through a recruiter. The process took 2 months. I interviewed at Aruba Networks in Jan 2022
Interview
Complete Waste of time and Effort. I recently interviewed for the full stack software engineering position at Aruba, Santa Clara.All the interviewers were great, they gradually increased the level of difficulty and were open to whatever approach you choose.There were a total of 7 rounds including Hiring manager, Coding and resume based and were insightful in terms to know the team you’d be working with.The recruiter was exceptional in terms of getting back to me and arranging the rounds.I did everything right, cleared all the rounds yet I received a rejection for no reason.It looked like they were just browsing the candidates and wasting time. Even after asking me if I was willing to accept their offer they rejected me. Doesn’t make sense at all, not to me. I have been actively interviewing and have never faced this.I don’t know if they even want to hire.
- The interviewers were considerate of your approach and found the leetcode to be easy to medium.

A wired network is the common type of wired configuration. Ethernet cables are the most widely used type of wired network connection for data transfer between connected computers. A single router can help connect all the computers in a small wired network. Numerous connected routers or switches are frequently used in larger networks.
A network configuration requires multiple configuration processes on server hardware and software, as well as networking equipment, making it a complex task to configure a network to support communication between an organization and its network owners. Setting a network’s physical, logical, and operational characteristics in a way that supports the owner’s overarching business plans is known as network configuration.
The Logical Link Control and Management (LLC/MAC) sublayer is the second OSI layer. The LLC is in charge of handling frame traffic and managing communications links, whereas the MAC controls protocol access to the actual network medium.
Layer 2, the data link layer of your network, is in charge of transferring data over the physical links in your system—switch communication. Install Layer 2 connectivity on your infrastructure to benefit from its fast speeds.
You can secure your network by implementing port security. It safeguards the network by preventing any unidentified devices from forwarding data packets. Additionally, it makes sure that in the unfortunate event of a link failure, all dynamically locked addresses are released. You can specify how many MAC addresses can be learned on a port using dynamic locking, while static locking ensures that only certain static MAC addresses are connected to a port.
A custom network created by one or more local area networks is a virtual local area network. Devices from various networks are combined into a single logical network to create a virtual LAN. The logical networks known as virtual local area networks (VLANs) are created from one or more physical networks. VLANs consolidate devices from different LANs into one logical network.
VLANs come in three different flavors: MAC-based, protocol-based, and port-based. Virtual area networks are grouped using ports in port-based VLANs, virtual area networks are grouped using protocols in protocol-based VLANs, and virtual area networks can be assigned to untagged packets using MAC-based VLANs.
In order to direct data to the appropriate location, the network switch, which is frequently connected to network learning, creates a table listing the locations of every device connected to it. The network switch won’t have to waste time looking for each device if it has a table of their locations. Unicast flooding, however, may result in intervals of subpar network performance or even complete network failure.
There are ideally four chief functions of a switch:
All network devices, whether wireless or hardwired, must have a media access control address (MAC address), which is a special identification number. It is automatically written into each network card and cannot be removed or changed. As a result, it is in charge of identifying each and every device on a particular network.
In a Local Area Network, a hub essentially serves as a connection point for a number of devices and has multiple ports. The data is instead received and relayed within a network by a switch using packet switching. Therefore, it is more efficient and intelligent than the hub.
How they deliver the data packets is where they diverge most from one another. In this scenario, a switch can save the addresses of linked devices and later learn each one, accelerating networks.
The address resolution protocol (ARP) is now widely used. When two devices are linked to a local area network, it serves as a bridge between the Internet Protocol, or IP, address and the Media Access Control, or MAC, addresses. It is advantageous that these addresses are the same length because the MAC address is specific to each device.
Spanning Tree Protocol, or STP for short, attempts to provide multiple layers of redundancy while removing loops typically caused during transmission. By establishing just one path between switches, this link management protocol lowers the likelihood of data loss and other network issues. In order to enable priority handling and recovery mechanisms, this protocol makes it easier for information to be exchanged via bridge protocol data units.
When a port is manually assigned to a VLAN, an administrator creates static VLANs, also referred to as port-based VLANs. As opposed to this, dynamic VLANs are made when a host connected to a switch via its hardware address is given a VLAN assignment.
The latter approach makes use of a central server called the VLAN Membership Policy Server, or VMPS, which has a database with all of the network’s devices’ MAC addresses. Such a server creates a VLAN to MAC address mapping.
It is a technique for identifying data packets moving through trunk lines, also known as frame tagging. By creating a VPN tag and transmitting it across the link, a unique tag is added to the frame. The frame is detagged and sent to the proper access link after reaching the end of the trunk line.
The router immediately transmits a data frame after receiving it. Once the frame has read the intended destination address, this is done to forward the frame to a different network segment. One of the most intriguing types of switching, this one is used in networks that are complex or extremely congested.
The sender, recipient, data contained, and an identification number are the four parts of a data packet. A data packet’s or datagram’s identification number, also known as an ID number, specifies the data packet or datagram as well as its position in the transactional sequence.
Data is transformed into packets whenever it is transmitted over a network. The packets contain all the information required to reconstruct the message correctly.
A computer network device known as the LAN, or local area network, links computers inside a specific building or location. It is a fast data network that connects workstations, servers, printers, and other IT hardware in a single building or campus. A good example of a local area network is Ethernet.
Contrary to LAN, which is constructed within a single building, MAN, or a metropolitan area network, is typically based on multiple buildings within a single city area. A good example is the IUB network.
WANs are extensive networks that connect numerous businesses or organizations, but they are not limited to just one. It forges a connection between several LANs. A good example is the internet.
A unicast is a direct information transfer from one source to another. The packets sent are relayed directly to the receiver. Among a group of network nodes, a broadcast is a one-to-all information exchange in which each node receives a copy of the packet containing the message.
As opposed to this, multicast involves the exchange of messages between a sender and numerous recipients. The network configuration, as opposed to broadcast, determines which devices receive the data. Last but not least, anycast is a technique for messaging between hosts that uses both the TCP and UDP protocols, sending a copy of each data packet to the correct recipient.
An IP address is translated to a physical device by the Address Resolution Protocol (ARP), which is orthogonal to the Internet Protocol (IP). The Media Access Control, or MAC, address is mapped to the IP address by the Reverse Address Resolution Protocol (RARP), in contrast.
Any device using the TCP/IP protocol suite is given a 32-bit to 128-bit identifier known as the Internet protocol address. The connected device is typically identified by a special number or symbol that makes it easy to tell what it is and makes it clear how it can communicate with other connected devices. There are two IP variants: IPv4 (the 32-bit variant) and IPv6 (the 128-bit variant).
When there is network congestion, it is possible for a node to carry more data than the system can support. In these conditions, packets and information are lost, which prevents the receiver from receiving the necessary information.
Switches have changed little in the past two decades. They obtain signals informing them which ports to send frames to, and they send those frames in accordance with the specifics of each port’s customized signals. Since the switch supports packet control whenever data is sent to the Data Link or the network layer of the OSI model, data packets are typically forwarded between multiple LAN segments.
Signals can be accessed when the switch examines the destination address because they are enabled during packet transmission, which is crucial to understand.
The OSI model consists of seven layers, each of which focuses on a different model component. The physical layer is the first layer, followed by the data link layer, the network layer, and the transport layer, followed by the session layer, the presentation layer, and the application layer. Furthermore, all of these layers have unique functionalities.
Between the presentation and transport layers of the OSI reference model is an application layer, also known as Layer 7. Developers of applets occasionally use this network layer to offer network services to communication components outside of those defined by the OSI model.
