Examples Of Waterfall Methodology Interview Questions With Their Answers

Listed below are a few questions connected to waterfall methodology, along with their sample answers:

What do you understand by the term 'waterfall methodology'? How does this approach get its name?

Interviewers might want to check if you possess the basic knowledge of the subject and may just require a concise answer. Consider defining the term in short and explaining how this model works briefly.

Example answer: "The waterfall methodology is a sequential development cycle that cascades like a waterfall through all stages of a project, where each subsequent phase begins after the completion of the previous stage. The model derives its name from a waterfall because it flows progressively from one phase to the next in a downward motion. Just like the water falling cannot go back to the source or in an upward direction, we generally cannot go back and change the previously completed phase. We use the output of one phase as the input to the following phase in this model."

What are the distinctions between the waterfall model and the agile model?

Your potential employers might wish to judge whether you possess the technical expertise to distinguish between different methodologies. Consider explaining both terms to differentiate between the two approaches and showing how they work.

Example answer: "Waterfall model is a classic method for project development that incorporates a linear process that begins with ideation and progresses through each stage in sequence until we finish and deliver the project. The agile model is a project development process that entails working faster to advance a project and making adjustments to the work based on client input. A waterfall project follows a predetermined path. We plan and clients interact at the beginning and end. The agile model is an iterative process in which we update the project with new goals and requirements after sprints and client feedback."

When do you choose the waterfall method over agile?

Interviewers may ask this question because they want to gain more insight into your suitability as a project manager and how well you can use and adapt the various models. Consider showing your versatility and experience as a candidate.

Example answer: "Well, I think that it mostly depends on the project's nature. If the specifications are clear and consistent from the beginning, the waterfall model is better. If a team has successfully handled similar operations, there is a major reliance on other projects and stakeholders are not easily accessible, the waterfall approach can be more useful. Agile methodology is more suitable for smaller, standalone projects where developing a minimum viable product (MVP) is critical."

Tips To Prepare Yourself For The Interview

Here are some useful tips to help you better prepare for your interview and become a successful candidate:

Re-examine the job description: Examine the keywords and phrases used by the employer to outline their expectations carefully. You get a greater likelihood of impressing the interviewer into giving you a chance if you can match your expertise and credentials to the job description.
Consider your qualifications: Consider your experience and background. Assessing how the job contributes to your career path and the value you can provide to the firm can assist you in persuading the interviewer that you are the ideal candidate for the job.
Research the organisation: Use the company's website, social media channels, employee reviews and other resources to learn more about it. If you are knowledgeable about the company, you can also offer purposeful questions to the interviewer, demonstrating your interest in the position.
Practice answers for the interview: Request a mock interview session from a family member or a friend and analyse it carefully. This can help you speak with confidence at the actual interview.
Organise the relevant documents: Arrange all of your relevant documents in a folder, including your mark sheets, certificates, ID cards and photographs. If the interviewer asked you to bring any specific documents, such as salary records, a release letter from your previous company or a bank statement, make sure you carry them with you.
Get ready for the interview: Ask about the office dress code beforehand. Make sure your outfit is neat and ironed and is not flamboyant.
Reach the venue early: Arriving early reduces nervousness and allows for mental preparation for the interview. It also helps make you seem reliable and punctual to your prospective employers.
