Agile Interview Questions

Overview of Agile

Earlier software projects used to be delivered late or under high pressure. Many customers did not use the features earlier thought necessary. This resulted in a waste of money and time. Many software developers thought about this problem and looked at delivering higher customer satisfaction as a primary requirement. This is why agile is born. Rather than lengthy documents agile focuses on face to face customer interactions and “usable” software approach.

The Agile Interview questions and answers we are mentioning below will help you to gain enough of the knowledge about Agile.

Advantages

  • Usable software delivered early.
  • Higher focus on customer satisfaction.
  • Flexible delivery module
  • Agile involves customers earlier

Development History

Agile is a set of guidelines which evolved with time. In 2001, the agile manifesto was developed by 17 software developers. Agile came into existence as a lightweight development methodology. Now agile is adopted in all companies.

All your questions related to Agile will be answered in the Agile interview questions mentioned below.

  • Agile methodology gives a faster return on investment in waterfall model the software is delivered at the end of the project total completion date. In agile software is usable in parts from the first iteration.
  • Agile involves customers earlier in the development stage, so errors in final delivery are less.
  • Agile also gives higher quality as testing is done a lot earlier and more frequently.
  • Agiles gives flexibility in developing software.

Key Performance Indicators provide guidance for the evaluation, strategic planning and for the improving operational processes. One of the essential indicators in agile is “Burn-down” chart. This KPI provides information related to the speed of delivery and is used to estimate if the project is on schedule. Velocity is determined by a number of story points delivered in a time box (or cycle or sprint etc.).

  • Spring Backlog is the most crucial part of an Agile Project. It is created during the preparation stage of the sprint.
  • Sprint Backlog is basically for the Team members so that they are able to align themselves during the Sprint. The team performs better with the assigned tasks that have to be done in a specific time.
  • The sprint backlog is tracked on an information radiator which provides a visual signal of the team progress, and it also points the scope of the ongoing sprint. As a result, the team is free from creating the burndown and burn up charts, and they know the current status of their work every time

velocity is the calculation of the amount of work the team has done in a specific time. Velocity in agile is calculated by adding up the total estimates, i.e. story points, days, ideal days or ideal hours of the user stories, requirements or the backlog items which were delivered within a previous iteration or previous Sprint.

Story points represent the level of difficulty in developing and deploying a used story. This gives a range of estimates based on how clear the user story is defined. Sometimes more massive points simply indicate lack of clarity in information and sometimes they suggest that user story is huge and needs to be broken in smaller units for delivery.

The burn-down chart is an indicator of a team’s progress towards entire project delivery. Each scrum backlog is plotted against the days in the sprint. The idea is to start with 100% work pending and end on 0% work pending. This gives the team a sense of direction.

1. Testing is done along with the development activity Testing is done after the development activity
2. It prefers that customer is available throughout the project It favors the customer only at the milestones

Between the sprints, spikes are created to resolve the design issues or the technical issues on priority in the ongoing coding projects.

There are two types of spikes:-

The functions spikes and the Technical spikes. Functional spikes are changes related to business use cases. Technical spikes are related to changes in executable code. Spikes needs attention as it is a disruption in standard delivery.

Sprint Zero in agile can be defined as the step before the first sprint. Sprint Zero includes the activities like setting up the development environment, preparing the backlogs that need to be complete before starting of the sprint.

This is the favorite interviewer question in Agile interview questions.

Refactoring of the code is a process in which the structure of the existing code is improved without changing the functional behavior of the code.

Purpose of refactoring the code:-

Refactoring of the code is essential while extending the code from iteration to iteration. If the code refactoring is not done, then the performance of the code deteriorate. This condition is called Software rot or code rot. As a result, the time and cost both are wasted.
