10+ Ethiopian Airlines Interview Questions and Answers

Retesting is the process of re-executing test cases that failed in the previous test cycle, while regression testing is the process of re-executing test cases to ensure that changes or fixes have not introduced new defects.

• Retesting focuses on the failed test cases from the previous test cycle.

• Regression testing focuses on ensuring that changes or fixes have not introduced new defects.

• Retesting is performed to validate that the reported defects have been fixed.

• Regression test...read more

Smoke testing is a type of software testing that checks the basic functionality of an application without going into details.

• It is a preliminary test to ensure that the critical functionalities of the application are working fine.

• It is usually performed after a new build is received or after a major change is made to the application.

• It is a quick and shallow test that helps to identify major issues early in the testing cycle.

• It is also known as Build Verification Testing (BVT...read more

The question asks to print the number with the highest frequency in an array of strings.

• Iterate through the array and count the frequency of each number using a hashmap

• Find the number with the highest frequency

• Print the number with the highest frequency

Defect tracking tool is used to track and manage defects found during testing.

• Defect tracking tool helps in identifying, reporting, and tracking defects in software.

• It helps in prioritizing and assigning defects to the respective team members.

• It also helps in monitoring the status of defects and their resolution.

• Examples of defect tracking tools are JIRA, Bugzilla, and HP ALM.

Microgrid is a localized group of electricity sources and loads that normally operates connected to and synchronous with the traditional centralized grid.

• Microgrid is a small-scale power grid that can operate independently or in conjunction with the main power grid.

• It can include distributed energy resources like solar panels, wind turbines, and batteries.

• Microgrids are often used to increase energy reliability, reduce costs, and integrate renewable energy sources.

• As an elect...read more

Print alternate numbers in a given array of strings

• Iterate through the array and print elements at even indices

• Use a loop to skip every other element while printing

Relays are used for various functions such as protection, control, and monitoring in electrical systems.

• Types of relays include protective relays, control relays, and monitoring relays

• CT (Current Transformer) and PT (Potential Transformer) are used for measuring current and voltage in electrical systems

• Types of breakers include circuit breakers, fuse breakers, and earth leakage circuit breakers

Use a loop to iterate through the array and print even numbers.

• Iterate through the array using a loop

• Check if each element is an even number

• Print the even numbers

Relays are used to control circuits by opening or closing contacts based on electrical signals, while circuit breakers are designed to protect circuits from overloads and short circuits by interrupting the flow of current.

• Relays are used for switching purposes, while circuit breakers are used for protection purposes.

• Relays operate based on electrical signals, while circuit breakers respond to current flow.

• Relays have contacts that physically open and close, while circuit brea...read more

Identifying symbols from electrical schematics is crucial for an Electrical Design Engineer.

• Study the legend/key provided with the schematic to understand the symbols used

• Look for common symbols such as resistors, capacitors, diodes, transistors, and connectors

• Pay attention to the shape, size, and orientation of the symbols to differentiate between components

• Use reference materials or software tools to cross-check and confirm the identification

Cb in circuitsss is the base-collector capacitance in a transistor circuit.

• Cb is an important parameter in transistor circuit design.

• It represents the capacitance between the base and collector terminals of a transistor.

• It affects the high-frequency response and stability of the circuit.

• Cb can be minimized by using a smaller collector-base junction area.

• Examples of circuits where Cb is considered are amplifiers, oscillators, and RF circuits.
