Ericsson Interview Questions, Process, and Tips for Experienced

The process of technology involves the development, implementation, and maintenance of tools, systems, and solutions to solve problems and improve efficiency.

• Research and development to create new technologies

• Testing and refining the technology to ensure functionality and reliability

• Implementation of the technology in real-world settings

• Maintenance and updates to keep the technology running smoothly

• Continuous improveme

Currently working as a software developer at XYZ Company.

• Developing web applications using Java and Angular

• Collaborating with team members to design and implement new features

• Participating in code reviews and testing processes

4G architecture includes radio access network (RAN), core network, and user equipment (UE) with interfaces like S1, X2, and LTE-Uu.

• 4G architecture consists of Radio Access Network (RAN), Core Network, and User Equipment (UE)

• Interfaces used in 4G architecture include S1, X2, and LTE-Uu

• RAN connects UE to the core network, while X2 is used for communication between base stations

• LTE-Uu is the air interface between UE and b

PRB can be calculated by dividing the total available bandwidth by the bandwidth per PRB.

• Calculate total available bandwidth

• Determine the bandwidth per PRB

• Divide total available bandwidth by bandwidth per PRB to get the number of PRBs

Load balancing can be done by distributing network traffic across multiple servers to ensure optimal resource utilization and prevent overload.

• Implementing a load balancer device or software

• Configuring load balancing algorithms such as round-robin, least connections, or IP hash

• Monitoring server health and adjusting traffic distribution accordingly

• Scaling resources up or down based on traffic demands

SD Congestion can be found by monitoring network traffic, analyzing performance metrics, and identifying bottlenecks.

• Monitor network traffic using tools like Wireshark or NetFlow

• Analyze performance metrics such as latency, packet loss, and throughput

• Identify bottlenecks in the network infrastructure, such as overloaded switches or routers

External interference can be removed by implementing shielding, using filters, adjusting frequencies, and improving signal strength.

• Implement shielding to block external signals from interfering with the network

• Use filters to eliminate unwanted frequencies that may cause interference

• Adjust frequencies to avoid overlapping with other nearby networks

• Improve signal strength to overcome interference from distant sources

LTE Accessibility formula calculates the probability of successful connection to the LTE network.

• LTE Accessibility = (RSRP - PL) - (UE Noise + Interference)

• RSRP: Reference Signal Received Power

• PL: Path Loss

• UE: User Equipment

My current CTC is $80,000 per year.

• My current CTC is $80,000 per year

• I am open to discussing salary expectations during the interview process

• I have experience negotiating salary based on skills and experience

Design patterns are reusable solutions to common problems in software design.

• Design patterns help in creating maintainable and scalable code.

• They provide a common language for developers to communicate about solutions.

• Examples include Singleton, Factory, Observer, and Strategy patterns.
