PhD Interview Questions and Answers (13 Questions + Answers)
Most PhD applications include an interview. This allows your university (and perhaps even your prospective supervisor) to discuss the PhD with you in more detail.
This article lists some of the most common PhD interview questions along with their answers. The goal is to help you prepare for a PhD interview and pass with flying colors.
1) How did you develop this proposal?
When responding to this question, demonstrate your thought process, research skills, and the evolution of your ideas. Let's choose the subject of "Renewable Energy Integration in Urban Planning" as an example.
Sample answer:
"My proposal on 'Renewable Energy Integration in Urban Planning' originated from my undergraduate thesis on sustainable cities. Intrigued by the potential of renewable energy in urban environments, I conducted a literature review to identify gaps in current research. This review highlighted a lack of comprehensive strategies for integrating renewable technologies at a city-wide level. I then consulted with experts in urban planning and renewable energy, which provided practical insights into the challenges and opportunities in this field. I designed a methodology that combines spatial analysis with energy modeling to explore optimal renewable energy integration in urban landscapes. This proposal represents an amalgamation of academic research, expert consultation, and innovative methodology development."
This answer is effective because it mentions a literature review demonstrates the ability to conduct thorough research and identify gaps in existing knowledge.
2) Why do you wish to pursue a PhD?
For this question, it's important to articulate your passion for the subject, your long-term career goals, and how the PhD program aligns with these aspects.

7) What difficulties would you expect to encounter during this project?
It's important to demonstrate awareness of potential challenges and convey a proactive mindset toward problem-solving. Let's choose a project focused on the development of a novel AI-driven diagnostic tool for early detection of neurological diseases for this example.
"In developing an AI-driven diagnostic tool for early detection of neurological diseases, I anticipate several challenges. Firstly, the accuracy and reliability of the tool depend heavily on the quality and diversity of the data used for training the AI algorithms. Obtaining a comprehensive dataset that adequately represents the population can be difficult due to privacy concerns and data availability. Secondly, ensuring the AI model's interpretability to be clinically useful while maintaining high performance is another challenge, given the complexity of neurological diseases. To address these, I plan to collaborate with interdisciplinary teams, including data privacy experts and neurologists, to source and utilize data ethically and effectively. I also intend to continuously refine the AI model, focusing on both its predictive accuracy and clinical applicability. These challenges, while significant, present valuable opportunities for innovation and interdisciplinary collaboration."
This response is effective because it clearly outlines realistic challenges specific to the AI diagnostic tool project. It also presents a proactive approach to overcoming these challenges, showing problem-solving skills.
8) How will you fund this project?
When answering this question, show that you've thought about the financial aspects of your research and are aware of funding sources that are available and applicable to your project.
"I have identified multiple funding sources to support my renewable energy research project at Stanford University. Firstly, I plan to apply for the DOE Office of Science Graduate Student Research (SCGSR) Program, which offers substantial support for projects focusing on sustainable energy. My proposal for this grant is already in progress, highlighting how my project aligns with the DOE's priorities in advancing clean energy technologies. Additionally, I'm exploring departmental fellowships at Stanford, particularly those aimed at renewable energy research. I am also keen on establishing industry partnerships, given the project's relevance to current energy challenges and the potential for collaborative funding and technological exchange.

9) Tell us about a time you experienced a setback
Focus on a situation relevant to your academic or research experience. Let's use a real-world example where a research experiment failed due to unexpected variables.
"During my Master’s thesis on the effects of soil composition on plant growth, I faced a major setback. My initial experiments, which involved growing plants in different soil types, failed to produce consistent results due to unanticipated environmental variations in the greenhouse. This was disheartening, especially as the deadline approached. However, I responded by reassessing my experimental setup. I consulted with my supervisor and decided to control more variables, such as humidity and temperature. I also refined my data collection methods to include more frequent soil and plant measurements. These adjustments led to more reliable results, and I successfully completed my thesis. This experience taught me the importance of adaptability in research and reinforced the value of meticulous experimental design."
This is a great answer because it shows how you’ve encountered and overcame a specific problem, demonstrating resilience and adaptability.
10) What are your strengths and weaknesses?
When answering this question, it's important to present a balanced view of yourself, showing self-awareness and a commitment to personal development. Choose strengths that are relevant to a PhD program and weaknesses that you're actively working to improve.
"One of my key strengths is my analytical thinking, which I demonstrated during my Master's project where I developed a novel algorithm for data analysis. This required me to not only understand complex theories but also apply them creatively to solve real-world problems. As for weaknesses, I sometimes struggle with overcommitment, taking on too many projects at once. This occasionally led to stress during my undergraduate studies. However, I am actively working on this by improving my time management skills and learning to prioritize tasks more effectively. I've started using project management tools and setting clear boundaries, which has already shown improvements in my workflow and stress levels."
This answer maintains a good balance between strengths and weaknesses. It also shows self-awareness, demonstrating a proactive approach to personal development.

What to wear to a PhD interview
Wear formal attire for a PhD interview. Your best bet is to wear a suit. A navy blue suit is the best and most versatile option. No matter your gender, a suit is always very professional.
For men, wear a suit with a tie, dress shirt, and dress shoes. For women, wear a suit (pantsuit or skirt suit) with a blouse, or conservative dress, and closed-toe shoes.
When in doubt, it’s better to be slightly overdressed than underdressed. The goal is to make a professional impression and feel confident, without your attire distracting from the conversation.
What to expect from a PhD interview
At its core, a PhD interview will consist of questions that allow your potential supervisors to get to know you better and have an understanding of what you’d like to study, why you’ve chosen your field of study, and whether you’d be a good fit for the PhD program.
You should expect general questions to help the interviewer get a sense of your likes and dislikes, and your overall personality.
Next, expect questions about your personal motivations for studying a PhD. Your interviewer will also be interested in any relevant experience you have to qualify you to study this PhD.
In the next section, expect questions about your PhD project. You should be prepared to discuss your project idea in detail and demonstrate to the interviewer that you are the ideal candidate.
Last but not least, the interviewer will discuss your future ambitions and give you an opportunity to ask questions. Remember that this interview goes both ways.
It’s important to ask the interviewer relevant questions to show your engagement and the serious consideration you are giving their program.
You are preparing to spend several years of your life at this school. Think about what is important to you and what would make or break your decision to attend this university.
Prepare a list of questions ahead of the interview.
