And for example, if you have a four to five good papers that you want to publish for a PhD, that would be a reasonable amount. You can also show that you are open to other approaches. So if you're not sure about your answer, you know, you can always ask your um interviewer, the professor about his or her own preferences because they may have their own preference. You can learn about it, but try to stay open and try to um show that you're you're ready to learn. you're um you're not very rigid in your approaches at least at this stage of the interview. That would be my strong suggestion. The next question is what will be difficult for you during PhD and what challenges will you face? So this question is not about you predicting what will happen during PhD. Okay? It's just about you showing your awareness that PhD can or even should be challenging you. It's also about you identifying those challenges in advance and seeing how you can cope with them. For many committees, you know, the worst case scenario is when a student who has wrong expectations about PhD faces those challenges and eventually quits. This happens on the one hand, you know, you uh you want to show that you understand it that it will not be easy. On the other hand, you're ready to be challenged and you will certainly win. Now, how to answer this question? One way is to look at the topic. If the project was described in the announcement or if you know which topic you want to pursue, you can just think about the challenges in this regard. For example, if your research will be in recycling of batteries, then you can just say that you're strongly motivated because better batteries can help us solve so many problems with energy storage, but the environmental impact of used batteries is too high. So, you really want to spend your PhD and perhaps postphd time on solving this issue. However, you are trained in materials engineering. You know, you're not an environmental scientist. You don't know environmental chemistry. So um you can see it as an initial challenge because you will have first to learn electrochemistry for your experiments and then um get some understanding of how batteries can impact the environment. So you will have to delve into the environmental chemistry field. So obviously learning new disciplines is a challenge that most PhDs have and that's totally fine to say that you're going in there being ready and having a certain background that will help you excel. Other examples can be poor skills in public speaking or you know difficulty with writing technical text um proposals maybe um insufficient training on complex instruments but at the same time I suggest that you avoid discussing challenges that are related to your most essential skills. you know, the skills that you're judged on. Uh those can include um learning abilities, uh problem solving, teamwork, core knowledge. For example, if you if you got a low grade in organic chemistry during your bachelor, mentioning this will probably not be good, right? It will not improve your chances during interview. The same goes if you say something like, I don't feel comfortable solving complex problems alone. So some committees may be fine with it because they encourage teamwork, but many many many adviserss will see it as a possible red flag because they want you to do your PhD. Often you have to do it on your own. That's the reality. There is another very important point. Uh each time you describe a challenge, make a breach to how you hope to solve it. Don't just mention your challenges. Give a clear picture as to how you will try to solve them. And of course um you know often one to two challenges is perfectly enough. Don't go over more than say three to um two to three challenges. That would be uh too much. Now before we get to the next set of questions uh I think that it's important to discuss a common one that uh is about the conflict resol uh resolution. If you get into a disagreement with a group member or a supervisor, how would you resolve it? So if you're in conflict with one of your group members over some sort of lab related issues you know which happen and it cannot be reasonably resolved by you then you should try to see if your PhD supervisor can help you which means you should say you would approach the professor and discuss the possible ways to resolve the issue always peacefully. Now while this is the right solution uh I I should also mention that there are you know different types of supervisors. There are professors who want to know about the conflict. Great I am myself like this and there are professors who don't feel comfortable resolving those conflicts inside the lab who want to be staying out of the conflict like you have a conflict try to solve it yourself don't get me involved. There are advisors like this. They may want to see that you will be doing your absolute best to solve it yourself first. And that's essential. So in some cases, you want to you want to say that you would look for an advisor from um your for an advice from your professor, but uh that you will also try not to get him or her involved at the beginning. So you will try to solve it first yourself. you will do your best.
